I need to get some new chain rings for my old roady. I have a feeling it's whatever standard Shimano is (130mm from what I've seen) but I don't know how to determine exactly. What is the that measuring?
And this stuff is so old that compact was not even in existence. It's an old Shimano 600 groupo that had Bio-Pace chainrings. It's my first bike that I bought with my very own $$$. I just want to get it running again for fun, but hate the bio-pace stuff.
Ah... BIOPACE, one of Shimano's many answers to questions that were never asked. If you ever follow someone with biopacerings you'd swear their rings where warped. ink:

Salsa makes both cheap rings w/o the shifting geegaws (cheap, lots of tooth counts), and the 'Pro' rings (more expensive, limited tooth counts) with the shifting rings. Remember you only need the ramps and stuff on the big ring...
