My stock '72 P15-9 has a low gear of 30.6 gear-inches with 700-25 tires. Schwinn used a rebadged Shimano Crane long cage derailleur labeled "Schwinn-Approved Le Tour GT-300" on the P15 on an otherwise Campy Nuovo Record equipped bike because it was vastly superior to the Campy Gran Turismo.



In contrast, the low gear on my Waterford RS-22 with a Campy compact double and the same tires is 30.9 gear-inches (34t chainring and 29t cog).

I can climb most hills around here on either bike, and I'm not that good a climber.
