Rear derailleur hanger Shimano Ultegra 6800/6870 11v - Y5YC98140

Shimano ’s Ultegra Y5YC98140 rear derailleur pulleys are genuine parts designed to restore the performance of your Shimano Ultegra 11-speed drivetrain. Compatible with the Ultegra RD-6800 and Ultegra Di2 RD-6870 derailleurs, they ensure precise chain guidance and contribute to smooth, fast and quiet gear changes.

Consisting of a guide pulley and a tension pulley, this replacement kit restores your drivetrain to its original performance after several thousand kilometres. Worn pulleys can cause noise, reduce the precision of gear changes and accelerate wear on the chain and cassette.

Manufactured to Shimano quality standards, these pulleys feature an optimised design to minimise friction and ensure smooth rotation. Replacing them regularly helps maintain the bike’s overall performance whilst improving pedalling comfort.

Ideal for maintaining a road bike fitted with an Ultegra 11-speed groupset, the Y5YC98140 Shimano pulleys offer a reliable and cost-effective solution for restoring a quiet and high-performance drivetrain.
