SRAM EX1 8 Speed Rear Mech Rear Derailleurs
  • £155.00
  • RRP £164.00
  • Saving you £5

The EX1 also benefits from many of the same technologies that are seen on SRAM’s top-end XX1 X01 mechs. This means it gives you lightning quick, accurate shifting and highly efficient chain retention. Technologies: 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. Roller Bearing Clutch™: SRAM's Roller Bearing Clutch™ rear derailleurs deliver maximum drivetrain stability, even through the most punishing terrain. With Roller Bearing Clutch™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision. X-Actuation™: Developed specifically for SRAM 1x™, X-Actuation™ keeps shifting sharp and consistent across the entire cassette. X-Horizon™: The X-Horizon™ rear derailleur's ‘straight parallelogram' design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears. X-Sync™: SRAM's X-sync™ pulleys and chainrings tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, helps manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1x™ drivetrain.

AXS technology means personalisation is in your hands. X-Range Optimised and Yaw Technology Due to today's drop bar bikes being faster and more capable than ever before, riders want a shifting set-up with wide-range gearing to match their wide range of cycling pursuits. But, as the range is only half of the equation, they also want a drivetrain that offers the right gear for any situation. This front derailleur is optimised for use with X-Range chainrings, so riders can enjoy fewer, faster front shifts, which makes it easier for you to find the right gear and offers a distinct performance advantage in comparison to traditional drivetrains. SRAM has also equipped this model with Yaw technology, where the front derailleur cage rotates to maintain a consistent angular relationship with your chain while eliminating the need for shifter trim. As a result, shifts feel more direct and precise, delivering an unmatched performance advantage in front shifting.
