race face onto shimano cranks
 

Would I be ok with putting race face chain rings to put on an older shimano crank

Thanks

Match the Bolt circle diameter.

As long as they have the same number of bolts and the BCD, they will work fine, that's what they are designed for being aftermarket rings.

As others have pointed out, if the BDC and hole pattern matches, they'll fit.

I ran some Race Face rings on my MTB a couple of years ago, and they shifted terribly. Only time that I've experienced chainsuck on that bike. I installed a new chain and cassette when I installed the rings, so everything was fresh.
