Yes and yes. The smallest ring was 44T. The track rings had an extra reinforcing rim around the inside of the ring. They were very substantial. Also the track rings were available in one inch pitch. Sugino made a lot of track rings in 151 BCD and they do not have the reinforcement.

> 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?
