Extralite UltraPulley Single Pulley
| Availability: | Out of stock |
The Extralite UltraPulley (Single) provides the same world-class performance as the UltraPulley Set but allows individual replacement or tuning of specific derailleur pulleys. Machined and assembled in Italy, each pulley combines a self-lubricating hi-tech polymer body with 7075-T6 aluminum inserts and Extralite’s renowned twin-bearing system—two precision micro-ceramic bearings per pulley.
The result is a pulley that’s ultra-light, exceptionally smooth, and impressively durable. Low-friction 2RS seals keep out contamination while maintaining near-frictionless rotation. Available in both phased (PH) and non-phased versions across several tooth counts (11T–16T), UltraPulleys are compatible with Shimano, SRAM, and Campagnolo mechanical and electronic drivetrains (10–12 speed).
How to check the clearance of your cage at each pulley. Measure the distance from the center of the pulley bolt to the inner edges of your derailleur cage. The table below shows the max diameter for each pulley model with chain installed. Divide by 2 the pulley diameter (with chain) and compare the result with your cage clearance
