1966 Campagnolo Record derailleur set

Ever thought about the number of teeth used on the rollers of the rear derailleur? Well, it's more than 9. In the transition from toothless to the now standard 10-11 tooth rollers there were these 9-tooth rollers. The tight bend in the chain lead to increased radial loads on the plastic pulleys resulting in them fracturing.

Live. Learn. Evolve.
