The Shimano Ultegra 6700 Pulley Set replaces the upper guide and lower tension pulleys on a range of Shimano rear derailleurs, including the RD-6700, RD-6600, and several XTR and Deore XT models. Built for 10-speed drivetrains, this set restores smooth chain tracking and consistent shifting once original pulleys show wear from road grime or extended mileage.
Each pulley carries 11 teeth to match Shimano's original gearing geometry. The upper guide pulley runs on a ceramic bushing for low-friction rotation, while the lower tension pulley spins on a sealed cartridge bearing that resists dirt and moisture. Together they keep the rear derailleur cage turning cleanly through every shift.
