New pedals for an old bike(7 posts)

New pedals for an old bikepjpinella
Apr 5, 2001 4:07 PM
I have a 25 year old Nishiki Competition road bike in mint condition (I bought it in college). I want to upgrade the pedals to a clipless variety; I use Time Atac on my mountain bike. But the spindles from way back then are different than today's pedals.

Does anyone know if anyone makes clipless pedals for an old bike like mine? Any help appreciated, thanks,

English threaded pedals have been 9/16x20 since I don't know when, so there is no reason that modern pedals won't fit. Are you saying your pedals are "department store" size (1/2")? If so, the bike is worth less than a new set of pedals, so skip the pedals and the bike, because you are saying you have a mint condition "Yugo". However, I'm guessing that a 25 year old Nishiki Competition has normal pedals. So please explain your statement that "the spindles . . . are different".

Kerry and all,
Thanks for your help. In terms of your question, I haven't actually measured the pedals, but the new Time Atacs definitely don't fit on the old cranks. I can't say if they are 1/2", they could be and I'll check. I like the following idea about having the cranks drilled and tapped, will look into it.

I'm thinking way back here, but seems to me the old standard was 1/2-inch, while modern bikes are 9/16. IF that's right, you could probably have the crankarms drilled and tapped to accept new pedals. A machine shop could give you an estimate, but be sure you leave enough metal around the new holes so you don't break the cranks. That would hurt...

it's got those Shimano AX or whatever cranks that required the dedicated AX pedals with the really huge spindle diameter... if that's the case, best bet is probably to sell the crank and BB or the entire bike and get all new stuff or just use what you've got
