I thought bending was bad for frames, and was not advised. In fact in I wasn't suggesting bending the frame (a PITA when changing the wheel if nothing else) but getting a shop to reset the rear to a different width.

What else do I need to consider? I konw it needs to have horizontal drop-outs. What about axle spacing? consider spd pedals, you'll get cornering clearance, and loosing a pedal because you forger you were on fixed is much more difficult If you need conventional pedals fit the thinnest and narrowest you can find. Shorter cranks or a nice fat tyre will help a lot. Fat tyres, no thanks! But yes, of course I would have SPDs. You can bend an old steel frame to any hubwidth you want, but hubs are available from 110 to 135mm I thought bending was bad for frames, and was not advised. In fact in the days when six-speed hubs were new, I remember reading strong warnings not to try forcing them to fit by bending. You shouldn't bend aluminium frames, they don't like it and are prone to snap. Not so much of a problem with steel. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ---===*** This space to let! ***===--- Yes!

Following recent bike misadventures, I'm considering taking up a friend's offer of an old frame, to turn it into a fixed-wheel bike. He says it's an old touring frame with "relaxed geometry". I've just picked it up. It's a Gudereit frame, "Veloring Esklusiv". A sticker on the seat post says "25 CrMo 4". There's another sticker indicating it might date from 88-91 (or maybe that's when it was sold). It has braze-ons for just about everything you could imagine, from a kick-stand to mud-guards and dynamo. The drop-outs are horizontal; the distance between them is 126mm. Does that sound like a worthwhile candidate for turning into a fixed-wheel bike? Daniele |

Is it because fatter tyres will make the necessary difference to pedal clearance (and wouldn't shorter cranks solve that problem)? Daniele |

Daniele it's probably designed with a lowish bracket and for 37mm tyres. 15mm shorter cranks is quite a lot, and for what? Decent running 35mm's will hardly be slower, much more surefooted if the roadsurface is bad, more comfortable.... -- /Marten info(apestaartje)m-gineering(punt)nl |
