It's not how fast you can go

Three days since my last entry and I'm writing again? Not since the heady days of the lamented According to Bex has this happened, so something must have happened. Something good, for goodness sake; woah, somebody's coming!

Who's coming up behind you is in fact a black clad rider on her fully armed and operational Lightning P-38.

I jest, of course. On my way home from work today I tried chasing down two roadies with calf muscles the size of pint glasses, astride carbon fibre bikes and working a cadence seemingly so slow as to suggest complete nonchalance towards speed, but my body was having none of it as I enthusiastically created whole clouds of weather around me while battling something slightly gunky inside my throat. I'd breathed in and swallowed a fly earlier in my commute, but had at least the presence of mind to wash it down as quickly as possible with a generous helping from my water bottle. There were actually four people on upright bikes taking on the long hill, a slightly chopped up three-quarters of a mile with 140 feet of climbing, and I dispatched the first one easily after my patience ran out at 7.5mph. The second I could have caught but my exit arrived before that; the roadies by that time had cleared off and were a further few hundred metres up the road. But to be fair, neither of them was carrying any luggage beyond perhaps their house keys, and my bike wasn't made of plastic and soot. I had also not cycled yesterday, owing to a commute on the VFR which itself had been pressed into service to let me recover from Sunday's bicycular theatrics. My knee is almost behaving, too, but Tabitha and I have been apart for the best part of eight months. Victoria's done her best to keep things in check, but she is a touch more slight on the Q-angle and on the crank length. 170 or 175? Aluminium or carbon? 3500 miles on the latter says it works for me, but only time will tell.

Having spent longer than I expected on Saturday fixing up the P-38's boom and front brake, and with the bike sitting with its full lightweight race pack, consisting of a custom made front light mount constructed from a Dremel'd-into-submission Busch & Müller fahrrad-rückspiegel bar end mount attached to 90mm of the lightest handlebar I could find, replacing the undoubtedly massively overbuilt and overweight Topeak Spacebar of the previous four years, and the dispensing of the curly Vistalite extension wire, we were now ready to burn rubber.

In the morning I headed over to The Bicycleworks to meet Andy, David, and whoever else intended to turn up, but strangely although I was on time as usual, no-one else was around; even more unusually even TBW didn't seem to be open. Perhaps they've gone to Peter's Yard, I thought, so I pottered through the Meadows in covert monitoring mode. There were some bikes parked outside but not any I recognised, and nor did I spot anyone familiar inside, so I parked up against a tree and watched and waited. Just then David came flying down the path so I waved and caught up, and we headed back to TBW whereupon Andy appeared. On the citycyclingedinburgh forum we'd had a slightly ridiculous discussion about Edinburgh's steepest roads, everyone making suggestions and the list being reduced to the top 10 or 20, along with what Gugol's maps and spreadsheets thought were their respective gradients. Obviously the roads had to be tested for cyclability, and Andy suggested a route that took in twelve of them. Some I was familiar with from being driven up them, another one I'd cycled once or twice (actually, probably a hundred times), and others I'd never visited at all. I had my GPS to record the day's ride to get some Real Data, and to show the planned route. In the absence of proper GPX route planning skills, that seems to have become my standard workflow for cycling with my GPS. I'll knock up a basic track using something like BikeRouteToaster, roughly following the planned route rather than letting it auto-follow the roads because that creates more than 500 trackpoints which, once I've navigated the execrable RoadTrip™, makes my Garmin shrug its shoulders and proclaim that it's truncated my lovingly prepared track. I can have the city map onscreen as I ride, with my nice green line showing up, and all I need to do is follow it. I even added a dozen waypoints with cute little names like 'OldFishMkt' and 'Gloucester', although the chances are that I would recognise a bloody steep hill when I got to it.

We quickly arrived in Blackford and had a brief warm up as we ascended Maurice Place, before turning right for Blackford Hill Rise, and rise it certainly did. The switchback brought us out onto Observatory Road, so it was only fitting that we cycled to the top to take photographs and carry out a little breath-catching. So far, so good, though I suddenly realised that there were another eleven to go. Retracing our steps we headed west through Morningside, Craiglockhart and out along the Water of Leith path to the former Colinton village railway station. A short loop brought us to Spylaw Bank Road, which I think I'd only been up before on my motorbike. Andy approved of the wall of tarmac, hemmed in by tall greenery, and put the hammer down a touch to leave me opting to take my time in my lowest gears. 'Aye, it's a wee toughie, that one!' I exclaimed at the top.



With the obligatory photographs taken we looped back down to the village and turned towards Bonaly and a short hop to West Mill Road, part of my "longer than usual, just because" commuting route back in my university days. We entered at the top and rode down, so naturally we had to ride up it for it to count, and then rode back down again.



Taking the back way out past the luxury flats built on the site of Mossy Mill and crossing the Water of Leith on an early Arrol bridge, we climbed up to the Lanark Road and took the fast road north through Wester Hailes, Sighthill and Corstorphine village. Kaimes Road was next on the list. less than half a mile long but about 250 feet of climbing. And it felt like it went on forever. As expected, Andy was first to the top, and I chugged away in 1st gear, sometimes reaching the heady speed of 6mph. After taking in the view and watching the Inverness to Kings Cross HST making its way towards Murrayfield, we descended. But only halfway, because Corstorphine Hill Road, the next block over, was also on the list. That one was pleasantly short, but just as sharp.

A careful descent took us all the way back down to the main road, and heated up my front brake just enough for it to start squealing. Crossing back towards Corstorphine we joined the old Pinkhill and Corstorphine branch line to Balgreen and Murrayfield, then followed the Water of Leith path to Roseburn, and up and onto the Roseburn railway path that is still mercifully free of trams. A slight navigational failure took us through Ravelston Dykes which meant that Bells Brae, the long, subsided, bumpy, cobbled climb from the old ford crossing of the Water of Leith in Dean Village, was met at the top. So we rode down it, up Hawthornbank Lane which David suggested as a bonus hill, back across to the top of Bells Brae (it would, of course, have made more sense to turn around...), down Bells Brae, pause for photographs, then up Bells Brae for it to count, then back down Bells Brae for the third time whereupon my bike fell to pieces. It didn't really, although my mirrors were making rattling noises. We took to the Water of Leith path again and turned off at India Place, just near the newly made allotments that would provide each budding gardener with a poky plot that was possibly more double bed than flowerbed. Enough to harvest a family-sized crop of potatoes, though, if the sunshine can penetrate the clouds.

Gloucester Street was up next, another long, subsiding, bumpy, cobbled climb up to Gloucester Lane, which was even worse, and which climbed all the way up to Heriot Row, which itself is on the way to George Street at the very top of the valley, with the Water of Leith at the base and Ravelston Dykes on the far side. Andy and I took ourselves up the hill while David took photographs, and then we took photographs of David hightailing it up on his superlight recumbent bike. From there, the onslaught of cobbles continued as we made our way to Drummond Place and Scotland Street -- possibly the very worst example of Victorian road surfacing in the whole of Edinburgh -- and to the bottom of Dublin Street: a ruler straight ascent up the side of the remnants of the glacier that carved out Princes Street Gardens. Dublin Street, being a not uncommon commuting route for me, and in fact part of National Cycle Network Route 75, is actually shallow enough a hill to be climbable on a six-speed Brompton with standard gearing, albeit at 4mph, and on my P-38 it disappeared in fairly short order.



After recordeding our ongoing success we took to the main roads of York Place and the mighty Picardy Place roundabout. I say mighty, in the sense of cyclists who say, 'It's really dangerous!' and 'Ooh, I never go there!', but not mighty in the sense of impressive, and possibly gutsy road engineering as befitting, for example, the multiple mini "Magic Roundabout" in Swindon. But it was Sunday anyway, and the traffic was minimal, which was a fleeting disappointment to us three intrepid riders who eat roundabouts for breakfast.

And so to Calton Hill. Cobbled, bumpy, short, and very steep. Closed to traffic, too, for many months not so long ago but more for nearby demolition and building work than being too difficult for the poor little cars. I can't remember who took it on first, but it might actually have been me. First gear, feet on the pedals and go, go, go. A few cars decided to make the ascent even more technical by trying to come down the hill at the same time, but I was having none of it and steered around them without missing a beat. All too soon the road levelled out and I turned around, parked my bike and fished out my camera. Andy was there too, and David came up shortly after. After a quick break we carefully made our way back down again, picking routes that hopefully avoided the worst of the tyre-sized gaps between cobbles, we raced down Lower Calton Road, swung right to pass under the East Coast Main Line, and right again and across more chopped up tarmac that in most places was doing an entirely bad job of covering the old cobbles underneath. Cranston Street was another short little climb, this time up the side of the 'tail' on which the High Street was built, and to which the 'crag' is Edinburgh Castle. David and I went up together in record time, neither of us even bothering with our nine smallest gears. Andy took his time, having photographed the route from the bottom, and then really put the hammer down as I did my best to capture the moment. Two more to go.

Down to the Cowgate, via a quick pitstop for me to buy a banana and Jelly Babies, and along the dank corridor of arches, rock clubs, pubs, slightly dodgy looking hotels, and innumerable closes with dank staircases. Daylight reappeared as we reached the Grassmarket, and we casually took ourselves up West Bow and Victoria Street, going up past Long Tall Sally, assorted 20-something shops with black t-shirts and skater clobber hanging in the windows, the tattoo place, the coffee place and so on. Victoria Street was so common and easy a route for us that we'd turned left and cycled across to the Mound and not taken a single photograph. The final assault was Ramsay Lane, a cobbled, bumpy, short and extremely steep little road that seemingly runs right up the side of the Castle Rock. It used to be open to cars whose drivers wanted to avoid the traffic lights of the High Street and George IV Bridge, but they've sort of closed it these days. Tickling my bike into its lowest gear and with my back firmly against my seat I set off. After Calton Hill I wasn't quite so scared and in fact I zipped up, barely breaking a sweat. It's pure skill, I'm sure. City of Edinburgh Council had even been so good as to paint a lovely double yellow finishing lane across the end of the lane and we stopped right there with a quiet little whoop and a possibly more obvious punching of the air from the mysterious black clad rider with the long hair.

Twelve hills in one day! Twelve and a bit, actually. And according to my GPS, a total of 2000 feet of climbing and we hadn't even left Edinburgh. To celebrate our incredible achievements we parked up at The Hub, all of 30 metres away, and spent the remainder of the afternoon enjoying a late lunch of hot chocolate, coffee and chips. David parted ways and aimed himself at the pub, while Andy and I rode out of town a little way before I took off for some more hills and my old standard of a three-quarter mile drag with bumpy tarmac.

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.
