Description
Shifting fast and smoothly, the SRAM X9 9 Speed Rear Derailleur (Medium Cage) is lightweight and designed to sit discretely on your mountain bike. For use with 9-speed drivetrains, the derailleur has aluminium alloy links and uses a forged B-knuckle design.
Sealed cartridge bearings are found in the upper pulley. These keep dirt and water out, meaning the X9 9 Speed Rear Derailleur will perform impeccably whatever the conditions.
The medium cage weighs just 204 grams. This scant weight is due to the outer cage's die-cast aluminium polished design.
Ideal for racing, training or just Sunday rides in the woods, the SRAM X9 9 Speed Rear Derailleur (Medium Cage) uses a 1:1 ratio and can offer immense shifting rain or shine.
