Model 1: XD-15 PULLEYS
Model 2: ZERO CERAMIC PULLEYS
Independently tested and winning competitions for the least rolling resistance, the truly best part of these jockey wheels is the silent and crisp shifting they afford. Machined from solid Delrin not molded, they are much harder and precise than any competitor's that have copied this design. Where aluminum jockey wheels are loud and deteriorate almost immediately after installing, Enduro Bearings jockey wheels will shift perfectly and precisely a year or two from now just the same as the day you installed them.
Model 3: CERAMIC HYBRID (CH) ABEC-5 PULLEYS
Machined from solid Delrin, these are machined smooth for easy cleaning and highly recommended for cross competition or mountain bike usage. Of course, they work perfectly for any ROAD application as well.
Model 4: SRAM XX1 ZERO CERAMIC PULLEYS
Created specifically with the SRAM XX1 drivetrain in mind, these jockey wheels are made of super hard, so0lid Delrin and machined to perfection. The unique 12 tooth, narrow/wide design allows for extra precise chain retention. ZERO ceramic bearings ensure crisp, smooth shifting in all riding conditions. These pullys can be used with all aftermarket chains.
