The ultimate upgrade pulley. Guaranteed to last forever against corrosion
Precision machined Delrin¬Ã Derailleur pulleys featuring XD-15 Ceramic-Hybrid, radial bearings for enhanced shifting performance and longevity.

It is engineered to stick to the balls and continually be pulled back into the ball path where it is needed.
