SRAM SX Eagle 12 Speed Rear DerailleuR

£69.99 £55.99


A high-quality rear mech which delivers excellent durability for tackling all the challenges that come with a long day in the mountains.


This stunning 12 speed rear mech is specifically designed for MTB use as it brings you the shifting performance you need to thrive on the trails. Its proven SRAM 1x-specific X-HORIZON design easily facilitates 11-50T and 10-50T cassette capacities for quieter and more consistent gearing. To top it off, it provides you with some of the finest industry-changing technologies at an affordable price.


Cage Lock: With Cage Lock technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just push the cage forward to create slack and lock it into place

X-Actuation: Developed specifically for SRAM 1x drivetrains, X-Actuation keeps shifting sharp and consistent across the entire cassette. This makes gears easy to index and provides exceptional performance.

X-Sync: X-Sync Eagle is the next evolution of SRAM X-Sync technology. The aggressive tooth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-Sync Eagle design reduces friction and the accumulation of mud, grit and grime.

X-Horizon: The X-Horizon ‘straight parallelogram' design limits all movement on the horizontal axis, which makes ghost shifting impossible while also reducing shift force. The large upper pulley offset design maintains a constant chain gap across all gears and guarantees faster and more exact shifting.
