Worked fine round town. I'm thinking 3 x 9 will be cheapish and robustish and not too clunky.

I have a 50T chainring on the back of my third hand orange recliner and 40T on front. 10-50 12 speed cassette - does actually work well but not cheap. In old money it delivers 20" to 100" gearing. Downhill it's one click short so spins out. Also got a 40 year old Raleigh Stowaway at shop with Sturmey 3 speed as my folding bike!

Tempted by the simplicity to replace my 3 x 8 but she was running out of gears at speed. Again, this only ever happens on a bike. No chance to admire another car's gearbox at the lights.

The rear mech was floppy, and replacing it allowed me to deduce that the rear shifter is worn out. It no longer indexes with the cassette. Can't complain. Nineteen years of a hundred gear changes a day adds up. In fact: chapeau, Shimano.

Sticker stuck back on the fork damper knob. Last three hose retaining clips replaced. I think the SUNLIT Uplander is now become whole. The Scaffolding Bike lives on in the changers, the last original parts from February 2000. I shall write to Shimano and congratulate them on the quality of their work.

At least you had a micrometer handy.

Quite fascinating. My error was a transposition of o-rings from the air-spring to the oil-damper sides. Tiny difference in size but the whole contraption was brought low by the resulting oil leak.

The neoprene o-rings in the service pack aren't labeled. I kind of tried to replace like with like and I'm pretty sure I've inverted the shaft seals on the spring and damping legs. So the oil is leaking past the piston on the damper side and collecting underneath. The travel is limited by the piston sitting on the oil. Let the air pressure out of the spring side and the damper piston can slowly sink back down through the oil underneath as the leak direction is reversed. Looking at a third session with the fork in bits to get the seals the right way round....

Nothing seemed to be out of place and the damper unit was passing oil as it should. Had a close read of the manual and realised I'd almost certainly simply over-filled the oil in the damper leg. Put it all back together and it seems to be riding fine so far. All fingers crossed. Re-set the brake calipers too. I'll batter it round Craigmillar Hill tomorrow evening for a proper shake-down.

I have performed operations for another model of the fork (the manual covers three) and managed to build it so that oil only goes past the rebound damping system downwards. So it's all gone into the fork legs and the piston is sitting on top of that incompressible fluid. Pretty stupid but I doubt there's any irreversible damage to anything except my fantasies of mechanical competence.

I have made a Mistake somewhere. New seal kit ordered, strip and re-rebuild.

Took the SUNLIT Uplander for a shake-down ride to the shops last night (finally got the stickers sorted out) and it was good. Any build of new and second-hand bits always takes a bit of fiddling to get silent running but that was pretty close. Rides sweet and, unlike madame IWRATS' bike, actually fits me. The one thing that was totally wrong was the fork which seems to have the travel half locked out. I suspect I've just put the knob back on out of line with the valve so that when it shows 'open' it's half shut but we shall see.

Interesting how stripping the lever has given me total confidence in that process. I've done it quite a few times but always with a nagging feeling the levers might operate by magic. Cranks on, rear mech on. Now to cancel my Vista print sticker order hahahaha. Ha.

Bicycling involves some mechanical complexity in return for speed and comfort. Cable-operated disc brakes should be fine, but in my experience they are designed to be upgraded - mechanically poor internals intended for a season or two at best and always a bit draggy. I like the plush feel of hydraulics and once you've got them set up they're very low fuss. I also get a testosterone rush from mastering the mechanics of them.

Checked all of the things. The problem lies with the lever which I got for £2 out of the Bike Station. Nothing I could do would persuade it to allow oil to flow into the reservoir past the master piston. It's supposed to be open as long as the lever isn't compressed. Baffled. Maybe that's why it was donated in the first place? wingpig on "The Scaffolding Bike" http://citycyclingedinburgh.info/bbpress/topic.php?id=19335&page=4#post-302539 Tue, 05 Mar 2019 10:10:41 +0000 wingpig 302539@http://citycyclingedinburgh.info/bbpress/ Keep typing or it'll stop moving.

Brake hose is in the post and yesterday I got the decals from Vistaprint. Applied the protective 3M tape to the drive-side chain-stay as a warm up, went to apply the branding and....they'd printed it on white rather than transparent backing. Doh.

Couldn't find the hose anywhere. Accused all and sundry of hiding or throwing it out. Checked Wiggle - I never actually ordered it. Remember now they only had the shorter front brake kit when I tried to buy. Phantom component syndrome. Bike Station and Co-op don't stock it, Pedals do but £13 dearer than Wiggle so another internet sale RIP high street.
