MTB Frame

jonaent (Jon) If you ride with 26" wheels, u will need a bigger gear ratio to ride fixed/singlespeed in order to have a decent urban top speed.... however the bigger the ratio the harder to skid and do stuff with your rear wheel.... which is the best thing about riding fixed.... without that control, or ability to skid you may as well be riding any old bike that you just can't stop pedaling on! Also, if it has vertical drop-outs just don't bother

Yeah a bigger ratio to get the same no of gear inches but the skidding on say 70" should be just as easy on a 26" or a 700cc wheeled bike.

tomiskinky I found this site which gives me the year and spec of the bike, only frame and forks are usable - http://www.vintage-trek.com/Trekpromoa.htm#pg7 It has a few scratched, but otherwise, very clean. Do want to put 700cc wheels on. Can anyone recommend a frame builder to put trackends put in? I'm based in East London and work in the West End. Thanks for all comments so far.

SO your bike is the 950 ? I expect it is ok. So does it have verticle of horzontal drop outs?
