A little while ago I was on a training course at work about writing economically and effectively and efficiently. Clearly there's a need to use plain english to aid the understanding of an audience whose familiarity with a topic could be close to zero, but indeed also serving, without overt oversimplification, an audience possessed of no little prior knowledge: an audience who quite rightly could feel offended at having to wade through ridiculous baby talk. They also encouraged us to construct short sentences. And, as part of the process that any half-decent writer ought to undertake before putting finger to keyboard, or as is my wont, pencil to recycled paper, how to write a plan—a brief, if you will. But I'm not at work, and I'm writing for the hell of it, so my plan involves only the words 'Brompton' and 'saddle', plus an answer to the question, Am I Sitting Comfortably?
The answer, for those of a more fragile disposition who might prefer as little suspense as possible, is a resounding No. More correctly perhaps, the answer is No, Well Yes, Well, Kind Of. And actually, sometimes I become just a little bummed out about the whole thing.
Many of you I expect might remember the halcyon days of bicycle accessory catalogues, when suddenly everyone had forgotten about Brooks and Carradice, but before the market became rad and funky and well crucial, when clothes turned from the nice, CTC-approved muted hues of blue and grey and greeny-beige that you could eat while enjoying cucumber sandwiches to the fluorescent assault of Bula and Chums and Oakleys with red lenses, alongside Cannondale's sideline in hot rod t-shirts with piranhas on the front. John Grafton probably hadn't yet graduated with his degree in numerical control part programming; your choice of consumer suspension forks was just one: an inventive upstart called Rock Shox; and Ground Controls were still the hot tip for riding up mountains. This was the day of the Selle Italia Turbo saddle.
It was one of those designs that seemed to fit everyone, and every kind of riding. Crusty old men with beards and saggy panniers who weren't using Brooks were probably using Turbos. Thirty-something men were using Turbos on steel Saracen Blizzards and Specialized Stumpjumpers for cross country mountain bike races, and twenty-something men were using them to ride to university. If you were a bit Brookish but liked the Turbo, you bought a San Marco Rolls instead. Women didn't have much choice but to use a Turbo or a Turbo-like Terry, because saddles with holes hadn't been invented.
I never even had a Terry. I had to make do with a horrible Matrix saddle at first, which became replaced along the way with an almost as horrible thing, a Selle Cattivo or Cuscino Basso Costo or San Luis Obispo, or something foreign-sounding like that. People with money later branched out, like the manufacturers who'd suddenly discovered elastomers and gel and computers, so you would see them perched on Turbomatics, Turbolites, Turbobios, Turbo Gels and Turbo ProTeams, or perhaps it would be something more deviant like a Vetta TriShock or Specialized's ProLong and Joe Blob saddles. By then, us girls could sit on Joe's partner, Betty. Really. Of course it all changed when someone invented titanium and the Selle Italia Flite was born. The original box had a picture of one in flight set against a cloudless sky, which I thought was brilliant. A saddle was now more than just something to sit on: it was a style icon of curves and expensive materials, and it was something that delighted the weight weenie brigade. For quite some time, the Flite was the coolest thing I'd ever seen. Later ones had Kevlar corners for gnarly stuff, or cheaper Vanadium rails which broke. They even made one out of carbon fibre but it was about a million Pounds and no-one bought it.
I did buy a titanium Flite though. I remember it cost as much as a nice pair of SPD shoes but I'd more or less destroyed the not very good stock saddle from my mid-90s Rockhopper and I needed a replacement. Well shoot but wasn't the Flite just the most comfortable saddle I'd ever tried? In fact, for at least ten years it was; it was absolutely perfect. The black leather top became polished to a brown sheen, the natty red stitched lettering gradually turned a pleasing shade of patina and it lived through summers and winters. Then one day it became the most unbearably uncomfortable thing and I just couldn't stands no more.
I did put on a little bit of weight, after all that sort of thing happens to people from time to time. But perhaps I simply wore out the poor thing; I certainly covered enough miles during that time, and what little padding it did have might have broken down under my super sharp sit bones. Perhaps in discovering the incredible and bizarre world of recumbent bikes I lost my hard-won toughness. Yes, that's it, I blame the recumbents.
I hadn't counted on the weather, though, to blunder in with its size twelves and ruin it all. With Speedy being my main machine and my rusty Rockhopper having died and been replaced with Annie the Blue Bike, complete with inherited Flite and living more and more in the garage complete with cobwebs and soft tyres, everything was metaphorically cool. The weather hadn't been so cool, because snow had become something that happened for a few days each year and was nothing much to bother about, but then it changed and I needed a go-anywhere bike that could plough through winter crud and snowdrifts. And I wanted a saddle with a hole in it. So one day I sat on some memory foam and found myself a Specialized Avatar with rinky-dink gel inserts, and it felt tolerably comfortable, at least when coupled with a bit of padding; it was ostensibly a bloke's saddle but frankly I was hard pressed to tell the difference because by then apparently blokes also wanted saddles with holes, and it was good enough to manage a few weeks' winter riding. But ride a recumbent bike for a few years and you really do begin to wonder why anyone in their right mind sits on an upright bike for hours and hours. Think again, and you realise that there is an awful lot going for crank forward designs, like the RANS Zenetik, Citi and Alterra. Somewhere in my (n+1) list is one of those.
So it's not terribly surprising that buying my Brompton, that most practical of little bikes, was to no little extent contingent upon the saddle and by extension the general riding ergonomics being anything more than just tolerably comfortable. Few would argue that the original Brompton saddle was a hideous piece of sticky black plastic covering a piece of foam whose non-Newtonian dynamics meant that the density changed from cotton wool to concrete upon application of any pressure greater than a fingertip, but the current iteration is really not too shabby. It does however have a major failing in the three-panel pretend leather top, whose twin rows of stitching are placed precisely to wear away at one's skin, largely independent of cycle shorts. This is probably why people buy the genuine Brompton-specific Brooks saddle. Obviously I am the exception that proves the rule because the Brooks is a massive and expensive hunk of gleaning brass and leather, and my Brompton is already well on the way to shoulder tearingly heavy. A Brooks would probably result in the formation of a blue hole and another rip in the bicycle-time continuum.
You may remember me luxuriating on such bicycles as the Lightning P-38 and the RANS Vsquared, with their highly engineered foam cushions and mesh seat backs. So why, in the name of all that is sensible, did I think unearthing a 16 year-old Flite for my Brompton was a good idea? The perception of absent things often improves in the fullness of time, and the feathery slip of leather and the mythical grey metal had long lain in a box to gather dust, and possibly spiders. I actually felt as though I missed the thing; somehow feeling sorry for casting it aside for some cheaper replacement. And of course, every bicycle improves when you add something made of titanium. An evening spent fiddling with seatpost clamp bolts and carefully eyeballed tilt angles and studied hip-knee-ankle ergonomics suggested I was good to go, so the next day I headed out on my commute.
'Oh good grief, it's hard as nails!' I complained, as I drew up to the main road after a couple of minutes' riding. Did I really ride this thing when I was younger? I must've been mad. It actually reminded me of those hard plastic saddles that were standard equipment on your Mag Burner, Falcon Pro, Supergoose, and pretty much any other BMX in 1980. Then I realised my riding style used to be all-out, where anything less than 20mph—uphill, into the wind, in the snow—was naturally hugely embarrassing. That kind of riding takes some of the weight off the saddle and carries it on the great force from your legs. By the end of the day I arrived home with a further 15 miles done and, amongst the swearing and the realisation that my riding position was suspiciously stretched out by about an inch because I hadn't cranked down enough on the clamp bolts the day before, I was ready to throw the infernal thing away. Good riddance to bad rubbish, I thought . . . but...those rails are titanium!
My masterplan of buying a cheap second seatpost in order to experiment with my collection of saddles without upsetting the finely tuned original Brompton setup took a bit of a crash after that. It might not be my preferred steed for reeling off 60 miles every day, or even 20 miles, and in fact it isn't, full stop, but 1500 miles on the clock and a bunch of relatively happy outings up and down the country does rather suggest that if the disarmingly friendly little bicycle ain't broke, don't fix it. So I won't, once I've given my Rolls a quick try-out, that is. And when that fails, because I'm sure it will, I'm going to get rid of them all.
I always knew there was a reason I liked recumbent bikes.

Don't go braking my heart
Victoria, my monstrous American recumbent, originally came with a pair of cable-powered Tektro disc brakes which in the hot dry conditions of the Erie Canal towpath were plenty powerful enough, and nicely progressive feeling. Even when racing downhill with a touring load there was about enough in reserve for shedding the miles-per-hour, but once in the Canadian thunderstorms the brakes squealed so badly that car drivers in front probably thought I was giving them both barrels on an air horn. Once back in the cold and damp of home, and in the close proximity of Edinburgh roads compared with the vast airy four-laners of Schectenady, the problem seemed even worse. It was downright embarassing actually. Dismantling the calipers, attending to tolerances and using copious amounts of copper grease behind the brake pads ended up, to my great bicycle mechanic chagrin, making no difference whatsoever.
In the end, I found a pair of second-hand Hope Mini hydraulics and promptly doubled their value by replacing all the pads, buying several metres of hose and the requisite unions, and rebuild kits for the brake levers. I'd had Hope Minis on my Speedmachine, and those ones worked superbly, so I had plenty of reason to assume these would be just as good. Mmm, no. I actually had to file down the diameter of the front disc because for some bizarre reason it was jammed in the caliper. But since then, the rear caliper has been dismantled, rebuilt and bled three times now because the pistons insist on extending more on one side than the other, resulting at best in a plaintive-sounding rubbing as I ride along, and at worst a stronger and stronger rubbing on the disc until it barely turns. If I'd had a modicum of sense, I would have rebuilt both brake levers and both calipers with new seals all round, but in my earlier enthusiasm I left things alone if they seemed good enough at the time. And when it rains, the Hope discs still squeal just as much as the Tektros. In fact, if I'd had any sense whatsoever, I would have bought Avid BB7 cable disc brakes right at the start.
I might've attended to the rear caliper pistons today, but I had more important things to do. I haven't been out on my Lightning P-38 since late last summer, after the frame clamp bolts distorted the aluminium boom. I'd had to install a new seat mesh because the original one started coming apart where the eyelets were pressed in, and the new wrap-around design actually shortened the distance to my pedals by about half an inch. Not much, you'd think, but half an inch is a big deal on an upright bike, and most recumbent seats have a fairly well defined sweet spot too. The raft of knee problems a year or so ago meant I was also trying out some shorter cranks, but that meant needing to lengthen the distance to the pedals as well. But the stubby little boom that Lightning supplied when I bought the frame simply wasn't long enough. So I mothballed my bike, and put the miles on Victoria and Henrietta instead.
But this week I finally received my replacement boom, in shiny black cro-moly steel rather than aluminium and a full two inches longer than the original (Lightning marked it as "XXL": this being installed on my already XL bike!). I had to bash a former into the frame tube first to expand the distorted clamp, although I'm not sure it made an appreciable difference. Then I left my brain in neutral while trying to install my FSA bottom bracket. Back to front. The worst thing was that I was nearly successful in screwing the left-hand threaded half of the BB into the right-hand threaded side of the BB shell. Pedals are easy: right-hand pedal, right-hand thread; left-hand pedal, left-hand thread. Bottom brackets: right-hand side, left-hand thread; left-hand side, right-hand thread.
It reminds me of that old sentence for remembering one's right from one's left. "I write with my right, and the one that is left is my left." But I, being left-handed, had to turn it around. Thus: "I write with my left, and the one that is left is my right." Well it's obvious, isn't it?
With the boom installed approximately, the bottom bracket, the cranks and the pedals quickly followed, then I cleaned up and installed the front dérailleur and the cable, and finished off with a few goes on the track pump for 85psi. A quick spin up and down the road told me I needed the pedals further out by a good half an inch, and this time there was boom length to spare. But look, the front brake pads are nearly worn out too! So on went a new pair of pads (peculiar orange and grey Ashima cartridge for V-brakes) too. Something wasn't right, though, and I realised that Ashima, like Clarke, has decided to make its pads twice as thick as Kool Stop does. My beautifully aligned pad holders then had to be realigned to take account of the wider spread of the V-brake arms, which then meant that my brake cable was just barely long enough to reach across. Perhaps I was being too much of a perfectionist but I think I revisited the pad holder positions about four times, trying to avoid the tyre sidewalls while setting precisely the right amount of toe-in and angling them just right so that they wouldn't drop off the bottom of the rim sidewall as they wore down. But with great serendipity I discovered in the bottom of my bag of spare parts my very last pair of Kool Stop pads! So the Ashimas went back on the shelf, and with the Kools in place I re-aligned the pad holders for a fifth time. After inspecting the brake cable I decided it probably ought to be replaced too, so I handily stole the original teflon-coated brake cable left over from my Brompton handlebar project. And heck, if I'm pulling out the cable I might as well replace the cable housing too and fix that missing inch on the length that's annoyed me for the last four years... After far too much fiddling—I even regreased the little bolt that holds the inner and outer dérailleur cage halves together—I think my P-38, the machine that was designed to be my flagship bicycle, is ready to hit the road again.
Meanwhile, little Henrietta Brompton, who lives in the corner, recently notched up her first 1000 miles. She's already sporting four new brake pads, a new rear rim and a miscellanous new spoke in the rear wheel as well. After work a few days ago I took a trip down through the Meadows, down the Innocent Railway path, past Portobello golf course and down to Portobello beach to pedal along the promenade and look at the big houses.

I finished up at the Dalriada Bar, having a mug of hot chocolate and a huge piece of lemon sponge cake, and sitting next to the open fire while reading my book for an hour or so. Of course, fold-fold-fold and Becky and bike went inside together. As I had expected and had prepared for by packing a jacket in my pannier, it was pouring with rain when I left to cycle home again. The Bar wasn't serving meals and I hadn't fancied eating in the Porto Café, which was both empty of other customers, and about half an hour from closing time when I looked in earlier, so I pottered the ten or so miles home on what felt like the most inefficient bicycle ever invented, finally giving up halfway to peel off my portable sauna of a Goretex jacket and opting to get wet instead. I was down on energy and I wasn't enjoying the saddle very much, but while my Brompton often feels too heavy, too slow, too undergeared, and too bumpy, the rest of the time it's so unbelievably convenient and disarmingly friendly that I always seem to end up forgiving it.

I disregard the writing and I play just what I feel
With the odometer sitting today at 676 miles, I have to say that I'm getting on really quite well with Henrietta Brompton. I haven't really written much about the little one who lives in the corner, but to be fair, I haven't written terribly much about anything of late, except perhaps how to justify owning more bikes.
After the false start in 2009, when the bike-to-be turned out to be no more than a potential collection of components, my Brompton arrived at the end of June 2010 with the help of Biketrax, here in Edinburgh. I'd previously test ridden several bikes in order to try to decide what options I would like: a two-speed with the low, flat handlebars was pleasantly light and stiff, but while Londoners get by very well with the minimal gearing, we have hills; a six-speed with the classic handlebars felt pleasantly tall, which was good news for my neck, and rather too flexible, which was bad news for my muscles; and in any case I found myself hopeless lost with the unusual gear changing between two sprockets and three in the hub. Over at Kinetics in Glasgow I'd tried a titanium version and marvelled at the weight reduction compared with steel, and I took myself around the block on a bike with the multi-position handlebars. I'd bought my Dahon with the intention of occasional folding and frequent riding, probably at some speed, and having decided that speed and distance was a recumbent bike's domain, my Brompton would stay in the court of more gentle and genteel trips.
I wanted to like the 'P-type' touring handlebars, with their controls on the top level and a narrow, low-level position for riding into the wind, but it felt like steering the top of a door. I quite liked the classic 'M-type' handlebar arrangement, but its two-inch height advantage over the flat 'S-type' bar also meant it used a shorter and more vertical stem. If I ever decided that I wanted lower handlebars, I might struggle to find medium-high rise conventional handlebar. On the other hand, with the S-type bar the riding position was low but not stretched out, and potentially good for cranking along and hill climbing within the range of acceptable power output for the bike. And if I ever decided that I wanted the handlebars a wee bit higher, or further forward, an aftermarket adjustable two-inch riser could be fitted, perhaps in tandem with mountain bike riser handlebars. I opted for the flat handlebars.
Gearing was really a no-brainer. Single-speed? No way. Two-speed? Aye, on a 1 in 7 hill? Three speed? Getting there but needs more range. Two-speed, and then fit a double chainring? Potentially a good idea, but it worked out about the same weight as the six speed. So, six speed? My final decision was for the six using the wide-ratio hub and a smaller chainring, which would get the bottom gear around 29 inches which is sufficient for most places in Edinburgh, and on the top end presumably I could simply freewheel if need be. Mudguards were required for weather, and I didn't need any lights because I had them already. I had planned to get Biketrax to order me an aluminium telescopic seatpost, as I had found that even the extended seatpost was laughably short for me. But when I discovered the price of it, and after I'd picked up my jaw from the floor, I decided to stick with steel and hang the extra weight.
And so remained the most important decision of all: the colour scheme. I spent literally hours playing with NYCeWheels' color picker page, and to tell the truth, I came up with several combinations I really liked: Race Green extremities (that is, fork, stem, swingarm) with Apple Green frame, Apple Green extremities with Race Green frame, Cobalt Blue extremities with Arctic Blue frame, White extremities with Arctic Blue frame ... and I tried other combinations to invoke national identities. How about the Cobalt Blue frame paired with White extremities to recall the halcyon days of Ecurie Ecosse motor racing; or the Race Green frame with Yellow extremities for Team Lotus. I even tried the vaguely camouflage colour scheme with the Race Green frame and Sand extremities. In the end, I chose the Arctic Blue frame with Sand extremities, since Sand was the closest colour to the lovely cream colour that Brompton formerly offered. Blue and Cream was, of course, the colour scheme of the English Electric DP1.
That was then. An early modification was to replace the foam handlebar grips with Ergon GP-1s for more contact area. Victoria already had them, and I liked them a lot. I also added some stubby bar ends, wrapped with bright blue tape to match the frame. A cheap Cateye Micro wireless computer from eBay seemed to do the job, and I installed one of my Smart 7-LED rear lights under the saddle. The hard plastic trolley wheels soon made way for a pair of Brompton's excellent Eazywheels, and I added my otherwise spare carbon fibre bottlecage to the stem. Before very long, I took the homemade aluminium rack that I'd built for my P-38, I prior to its Blackburn EX-1, and fashioned it into a frame to take a second pair of Eazywheels at the back of the bike. The Brompton rear rack would have done, at the expense of even more weight; my frame wasn't designed to be structural. Now the folded bike could be rolled along with aplomb.
For 500 miles and more that was my bike. But those S-type handlebars while fine for my hi-NRG commuting were just too low down for more than 15 or 20 miles at a stretch, and something had to be done. A sidenote in an edition of Velovision had shown the adjustable riser, ostensibly for tandem stoker bars, and JD Cycles the only apparent stockist. Having hummed and hawed for months, they were out of stock when I actually wanted one. At long length I found one on the ThorUSA site, and at even longer length found one on the eBay arm of Practical Cycles in Lancashire (where both Hope Technology and Carradice reside). And from the sale at Edinburgh Bicycle I came out with a carbon fibre riser handlebar. The big changeover wasn't quite that easy, because all of the cables on a Brompton are fairly specific in their length: too short, and the bike doesn't fold properly; too long and the pedal or the crank or your foot will catch on them; put them on in the wrong order and the bike doesn't fold properly... With the riser and the handlebar, two brand new gear cables and two brake cables, plus four lots of housing, it was a day of measure, test, check, measure, check, cut, and four times at least. But it all came good in the end, and with the handlebars cut down to the same width as those of the Dahon, and my original Onza bar ends installed at last, I was in business!
And then while riding to work one day, I had my first flat tyre on the bike. Naturally, it was the back tyre, and I hadn't rehearsed the procedure for removing the wheel. It wasn't terribly far, so in the interests of saving money by not catching a bus or a taxi with my bike, I trudged home and went out on Victoria instead. It turned out to be a tiny arrowhead-shaped piece of grit that had gone through the Schwalbe Kojak's tread (if you can describe a slick tyre as having 'tread').
The rear wheel process turned out to be very easy once I'd looked at the pictures in the owner's manual and ignored the text -- after all, it wasn't rocket science: second gear, bike upside down, remove the hub toggle chain, remove the window nut, fold the wheel, detension and unship the chain, remove the tensioner whole, loosen the axle bolts, wheel out. The only picky bit is setting the cable tension on the gear cable, which is simple with a torch: in second gear the end of the screwed rod lines up with the end of the axle, as you look through the little window nut.
But 676 miles later, today I was finally fed up with the notchy, self-centring steering, the gritty front wheel bearings, and the rattling fork hook. So I took everything apart, replaced yucky brown grease (where there was some) with shiny black Castrol Moly Grease, and put everything back together. The headset's locknut washer decided to rotate as I tightened things up, which didn't help matters, and the cones on the front axle were seemingly either gritty and tight, or rattley and loose, but I bent them to my will in the end.
Next stop: tweaking the cones on the rear axle, and eliminating the monumentally annoying rattle of the Brompton 3-speed shifter!

Gearing was really a no-brainer. Single-speed? No way. Two-speed? Aye, on a 1 in 7 hill? Three speed? Getting there but needs more range. Two-speed, and then fit a double chainring? Potentially a good idea, but it worked out about the same weight as the six speed. So, six speed? My final decision was for the six using the wide-ratio hub and a smaller chainring, which would get the bottom gear around 29 inches which is sufficient for most places in Edinburgh, and on the top end presumably I could simply freewheel if need be. Mudguards were required for weather, and I didn't need any lights because I had them already. I had planned to get Biketrax to order me an aluminium telescopic seatpost, as I had found that even the extended seatpost was laughably short for me. But when I discovered the price of it, and after I'd picked up my jaw from the floor, I decided to stick with steel and hang the extra weight.
And so remained the most important decision of all: the colour scheme. I spent literally hours playing with NYCeWheels' color picker page, and to tell the truth, I came up with several combinations I really liked: Race Green extremities (that is, fork, stem, swingarm) with Apple Green frame, Apple Green extremities with Race Green frame, Cobalt Blue extremities with Arctic Blue frame, White extremities with Arctic Blue frame ... and I tried other combinations to invoke national identities. How about the Cobalt Blue frame paired with White extremities to recall the halcyon days of Ecurie Ecosse motor racing; or the Race Green frame with Yellow extremities for Team Lotus. I even tried the vaguely camouflage colour scheme with the Race Green frame and Sand extremities. In the end, I chose the Arctic Blue frame with Sand extremities, since Sand was the closest colour to the lovely cream colour that Brompton formerly offered. Blue and Cream was, of course, the colour scheme of the English Electric DP1.
That was then. An early modification was to replace the foam handlebar grips with Ergon GP-1s for more contact area. Victoria already had them, and I liked them a lot. I also added some stubby bar ends, wrapped with bright blue tape to match the frame. A cheap Cateye Micro wireless computer from eBay seemed to do the job, and I installed one of my Smart 7-LED rear lights under the saddle. The hard plastic trolley wheels soon made way for a pair of Brompton's excellent Eazywheels, and I added my otherwise spare carbon fibre bottlecage to the stem. Before very long, I took the homemade aluminium rack that I'd built for my P-38, I prior to its Blackburn EX-1, and fashioned it into a frame to take a second pair of Eazywheels at the back of the bike. The Brompton rear rack would have done, at the expense of even more weight; my frame wasn't designed to be structural. Now the folded bike could be rolled along with aplomb.
For 500 miles and more that was my bike. But those S-type handlebars while fine for my hi-NRG commuting were just too low down for more than 15 or 20 miles at a stretch, and something had to be done. A sidenote in an edition of Velovision had shown the adjustable riser, ostensibly for tandem stoker bars, and JD Cycles the only apparent stockist. Having hummed and hawed for months, they were out of stock when I actually wanted one. At long length I found one on the ThorUSA site, and at even longer length found one on the eBay arm of Practical Cycles in Lancashire (where both Hope Technology and Carradice reside). And from the sale at Edinburgh Bicycle I came out with a carbon fibre riser handlebar. The big changeover wasn't quite that easy, because all of the cables on a Brompton are fairly specific in their length: too short, and the bike doesn't fold properly; too long and the pedal or the crank or your foot will catch on them; put them on in the wrong order and the bike doesn't fold properly... With the riser and the handlebar, two brand new gear cables and two brake cables, plus four lots of housing, it was a day of measure, test, check, measure, check, cut, and four times at least. But it all came good in the end, and with the handlebars cut down to the same width as those of the Dahon, and my original Onza bar ends installed at last, I was in business!
And then while riding to work one day, I had my first flat tyre on the bike. Naturally, it was the back tyre, and I hadn't rehearsed the procedure for removing the wheel. It wasn't terribly far, so in the interests of saving money by not catching a bus or a taxi with my bike, I trudged home and went out on Victoria instead. It turned out to be a tiny arrowhead-shaped piece of grit that had gone through the Schwalbe Kojak's tread (if you can describe a slick tyre as having 'tread').
The rear wheel process turned out to be very easy once I'd looked at the pictures in the owner's manual and ignored the text -- after all, it wasn't rocket science: second gear, bike upside down, remove the hub toggle chain, remove the window nut, fold the wheel, detension and unship the chain, remove the tensioner whole, loosen the axle bolts, wheel out. The only picky bit is setting the cable tension on the gear cable, which is simple with a torch: in second gear the end of the screwed rod lines up with the end of the axle, as you look through the little window nut.
But 676 miles later, today I was finally fed up with the notchy, self-centring steering, the gritty front wheel bearings, and the rattling fork hook. So I took everything apart, replaced yucky brown grease (where there was some) with shiny black Castrol Moly Grease, and put everything back together. The headset's locknut washer decided to rotate as I tightened things up, which didn't help matters, and the cones on the front axle were seemingly either gritty and tight, or rattley and loose, but I bent them to my will in the end.
Next stop: tweaking the cones on the rear axle, and eliminating the monumentally annoying rattle of the Brompton 3-speed shifter!
