Why do commuters on racers do that? They have a zillion gears to chose from and they use one, I think that they are all training to go fixed! :?:
if they are anything like my commuter then the front and rear mechs are rusted solid and they've no choice but to stick in one gear :?:
sybarite, could well be traning but not to ride a fixed. The other thing is they may be relieving the pain in the buttocks!!!!!!!!!!!!!!!!!!!!!
