Carbon jockey wheels
Gemini Ögle Aero Carbon Pulley Wheels for Shimano
Oversized forged-carbon jockey wheels with ceramic hybrid bearings that fit your stock Shimano rear mech cage. Versions cover Dura-Ace, Ultegra and 105 Di2, GRX, and XT/XTR mountain groups.
Highlights
Why we rate it
Forged carbon bodies
Continuous carbon fibre is moulded right around the teeth, keeping the pulleys light while staying stiff for crisp shifts.
Oversized, no new cage
Each set uses the largest teeth your stock derailleur cage can take, so you get lower chain articulation without an aftermarket cage.
Ceramic hybrid bearings
Ceramic balls roll more freely than standard steel bearings, trimming drivetrain friction.
Sealed, spokeless design
Solid faces keep grit out and are cleaner aerodynamically than open-spoke pulleys.
Handmade in Barcelona
Produced in Gemini's own workshop alongside its carbon chainrings.
