Shimano Dura-Ace RD-9000 / RD-9070 Derailleur Pulley Set

Restore your premium road machine to factory perfection with the authentic Shimano Dura-Ace RD-9000/9070 Rear Derailleur Pulley Set. Positioned at the very top of Shimano's cycling hierarchy, Dura-Ace components demand exacting tolerances. Worn jockey wheels introduce unwanted side-play and grit friction, compromising the ultra-sharp shifting response your high-end bike was designed to deliver.

This master-tier replacement set features dual precision-sealed cartridge bearings. These ultra-low-friction bearings ensure maximum watt savings across every pedal stroke while robust seals protect the internal mechanisms from rain, grime, and road salt. Designed to handle both top-tier mechanical and electronic Di2 systems, these jockey wheels provide near-silent chain execution under extreme racing loads.

Key Features & Benefits:

• Flagship Sealed Cartridge Bearings ($\times2$): Both the guide and tension pulleys are armed with professional-grade cartridge bearings for the lowest possible rolling resistance.

• Pro-Tour Shifting Precision: Restores the lightning-fast, crisp, and predictable 11-speed gear tracking required at elite racing levels.

• Ultra-Lightweight & Rigid Resin: Crafted from an advanced self-lubricating composite that dampens drive noise while offering superb wear resistance.
