What was the smallest (least number of teeth) chainring designed as the outside ring for a Campagnolo 151 pattern crank? And was there a specific chainring designed for track cranks that differs from their road chainrings?

Thank you.

Cheers.

Hi Tom: 44 - there are no differences between "inner" and "outer" 151 (or early 144) Record road chainrings. The overshift pin came later (maybe 1974ish... I'm not sure of that date), and was included on size 50 and up IIRC . Yes on the Pista question - the early (and maybe all?) 151 Pista 'rings are very beefy, with an "extra" thickness of material just inboard of the teeth on the inside face. Multo cool, IMO, and Mega-stiff. I happen to know someone that has a few of those available NOS in the 50-tooth size.... Greg Parker Ann Arbor, Michigan
