SHIMANO DURA ACE RD-9000/9070 TENSION & GUIDE PULLEY WHEELS
The Shimano Dura-Ace RD-9000/9070 Tension & Guide Pulley Set is the definitive factory-spec replacement designed to restore the ultra-precise, lightning-fast shifting performance of Shimano's premier 11-speed mechanical and electronic Di2 road groupsets. Over thousands of kilometres, standard jockey wheels naturally experience tooth profiling wear, resulting in micro-movements of the chain, increased mechanical friction, and a less responsive feel at the gear levers. Swapping out your worn components for this genuine, premium jockey wheel set eliminates drivetrain slop and ensures absolute chain-tracking accuracy.
Engineered to meet the exact tolerances required by professional road racers, this complete set includes both the upper guide pulley and the lower tension pulley.Unlike mid-tier options that rely on basic bushings, both of these 11-tooth wheels are packed with high-grade, sealed precision cartridge bearings. This dual-bearing configuration drastically slashes rotational drag, ensuring every watt of your pedalling input travels directly to the rear wheel. The structural composition is tuned to dampen high-frequency chain vibration, resulting in an exceptionally quiet drivetrain even when sprinting under high loads or grinding up steep tarmac climbs. Equipped with advanced low-friction seals, this kit protects the internal factory grease from rain, road grit, and degreasers, delivering long-lasting mechanical efficiency in all weather conditions.
Key Features
Dual Sealed Precision Bearings: Fully sealed cartridge bearings inside both wheels dramatically lower rolling resistance and maximise drivetrain mechanical efficiency.
11-Tooth Optimized Architecture: Specifically designed profiles ensure smooth chain pickup, reducing noise and power losses as the chain snakes through the rear derailleur cage.
Flawless 11-Speed Tracking: Guarantees factory-original lateral tracking accuracy, allowing instant, crisp gear transitions for both mechanical (9000) and Di2 (9070) systems.
Vibration-Dampening Composition: Engineered composite material limits friction and isolates chain noise, delivering a incredibly quiet ride across the cassette.
All-Weather Resilience: Advanced internal rubber lip seals block out road spray, winter salt, and abrasive dust to prevent premature bearing pitting and drag.
