Gemini ÖGLE Carbon Pulley Wheels for SRAM RED / Force / Rival E1 – Ceramic Bearings
Refine your SRAM road drivetrain with Gemini ÖGLE carbon pulley wheels for RED, Force and Rival E1 12-speed rear derailleurs. Handcrafted in Barcelona, these lightweight jockey wheels combine forged carbon construction, hybrid ceramic bearings and a distinctive enclosed design.
The 12-tooth upper and 16-tooth lower pulleys fit the original derailleur cage, allowing you to upgrade without replacing the complete cage. Their larger diameter is designed to reduce chain articulation, while precision ceramic-ball bearings support smooth rotation with low rotational friction.
Key features
Forged carbon construction: carbon fibres moulded continuously around each tooth for a lightweight, rigid structure.
Hybrid ceramic bearings: precision bearings with ceramic balls for smooth running.
Original cage compatibility: fits the standard SRAM E1 road derailleur cage without an aftermarket cage conversion.
Enclosed, spokeless design: a clean aerodynamic profile that helps limit debris entering through the pulley body.
Anodised aluminium covers: complete the bearing assembly.
Handcrafted in Barcelona: designed and manufactured in-house by Gemini.
