L-TWOO Ceramic Bearing Carbon Fiber Jockey Pulley Wheel Set for Rear Derailleur

L-TWOO Ceramic Bearing Carbon Fiber Jockey Pulley Wheel Set Features and Specifications

These jockey pulley wheels use full ceramic bearings, which produce less friction than steel bearings and maintain smooth rotation under load across thousands of kilometers without degradation. The carbon fiber cage sheds grams from your drivetrain where it counts most, reducing rotational inertia on every pedal stroke. Each wheel is precision-machined to match the tooth profile of Shimano 105, Ultegra, and DURA ACE rear derailleurs, ensuring clean chain engagement at every gear position. Ceramic bearing technology resists moisture and contamination better than steel, so performance stays consistent in wet or dusty conditions without heavy maintenance. You get a direct drop-in upgrade that reduces drivetrain energy loss and delivers a noticeably smoother, quieter chain path — shop now through the official store for the best available price.
