Hi i've bought a 1988 Marin Bear Valley, what size pedals does it require?
is it metric or imperial?

Re:

wrong section.......but ...will be 9/16. Might have a pair off a 1988 pine mountain if interested. Probably got a nice replacement for that exage rear mech too

thanks, my first post and screwed it up.
i fancy the shimano saint flat pedals, if i can find them cheaper than retail.
