You lost focus for just a second over that last set of jumps, and the subsequent bail has left your derailleur in pieces and a little less cash in the bank once you're done getting stitched up. Get back up and running with SRAM's GX DH 7-Speed Rear Derailleur. It's built tough to withstand gravity abuse and won't set you back a broken arm and leg to get your favorite gravity machine back to the lifts.
The GX1 DH 7-Speed Rear Derailleur packs in all of SRAM's top one-by engineering to ensure rear shifts are smooth, accurate, and predictable. Starting with the offset pulleys, the tall square-toothed X-Sync profiles work to positively engage and manage the chain better than traditional pulleys. These pulleys work in conjunction with the X-HORIZON's straight parallelogram design, which limits all movement to the horizontal axis, thus eliminating ghost shifting and reducing shifting force. SRAM's proven Roller Bearing Clutch is also present, which delivers maximum drivetrain stability by maintaining consistent tension on the chain—even while riding in the most demanding conditions. Finishing off the rear mechanism are sealed cartridge bearings and SRAM's handy Cage Lock design that keeps the derailleur locked out of the way for easy rear wheel installation/removal.
