There is into this interesting mix, to be put, the factor of the actual interface between block and rim. If the rim is smoothly polished and no metal shards are embedded in the block wear rates are very very much reduced. Such a polished rim surface can be promoted by always easing/ stopping brakin...

fitting for what end purpose though? a fitting to produce a bike for racing (TT even) would give a different result than if you asked for a bike you could ride loaded all day.

the software only picks up on text such as 'fatigue,' 'sturmey.' 'drum' etc etc

Bike Related Unlimited-Content (or Bru-C) is software originally written on the ZX81 but now upgraded to the latest platforms. Book?

wasn't there also an oversized tubset in 631?

the rear sprocket moves laterally to simulate changes in angle but it doesn't simulate the chain being pushed around by the mechs nor climbing the teeth and re-engaging a new sprocket.

$76 for a chain?

old thread alert. the first inkling of a broken seat post collar this week was a feeling of being underpowered on the bike. it wasn't fatigue, it was a slipping saddle height. a crack in the collar had allowed it to slip some 5mm (over time i suppose.) i didn't really feel that odd on the bike posit...

I'm surprised no-one has suggested stuffing the seat tube full of socks....

cheers

it crossed my mind yesterday.

bit 3 bears this. 28.6 too small. 31.8 too big. 29.8 juuuust right. i think you were correct there upthread.

Hi Too late now, but my steel frame has a 31.8mm. I have a collar around the seat post as well for a couple of reasons: Emergencies like this :) It marks my saddle height should it need to be removed for any reason It's somewhere to attach my Carradice Bagman and can be moved around more easily Reg...

I would have thought that one part spared was that.

it's annoyingly blank.

just to say that 8 miles whilst standing on the pedals on a fixed bike is a PITA.

there are plenty of TIG welded steel frames that use an externally flared seat tube so that they need a larger collar than you might expect, e.g. around 30mm. [Dunno about a Pompino, but otherwise if it is 27,2mm seat pin with a 28.6mm clip the tube has to be no more than 0.7mm wall, which is too t...

pompino frame.

mine broke on arrival at work this morning

never bought one before. what size for a steel frame with 27.2 seatpin?

got to ride the thing home standing up later.

it's fixed gear
