SRAM XX1 11 Speed Rear Derailleur

XX1 is SRAM’s newest drive train group, designed to simplify the traditional mountain bike drivetrain and make it more efficient. The XX1 X-Horizon rear derailleur features a horizontal parallelogram design that eliminates vertical movement, creating a derailleur that shifts faster, requires less force to shift, and eliminates ghost shifting. The XX1 X-Horizon rear derailleur also features a roller bearing clutch that helps minimize chain slap and bounce, and makes rear wheel changes a breeze.
  • Only compatible with XX1 components
  • Large upper pulley offset automatically adjusts chain gap
  • Straight parallelogram design with horizontal movement reduces shift force and improves drivetrain performance
  • 12T X-SYNC pulley wheels
  • TYPE 2 technologies: ROLLER BEARING CLUTCH™ and CAGE LOCK™
  • New silent pulley tooth design
  • Weight: 220 grams

SRAM revolutionized MTB with XX1
SRAM's best MTB component to date! XX1 is the absolute greatest thing to happen to MTB components. I will never go back to a 2x system ever again. There is more than enough gear range in a 1x system to tackle any trail.

The XX1 rear derailleur is smooth and reliable. the clutch system has NEVER allowed a thrown chain and coupled with the XX1 twist grip, the shifts are flawless. I don't find myself ever needing to adjust the cable tension to make shifting better. Again, XX1 is perfection!

Jenson USA's prices on XX1 are low and customer service is great. That's why I shop Jenson online!

Awesome
Installed the XX1 drivetrain on the wife's bike, and she was able to test it thoroughly for a week in moab and fruita. Butter-smooth shifts, seems to be durable (got a couple crash tests in), and cut a lot of weight off the bike. Running a 32t front ring seemed perfect for her liking, and she had zero complications through 80 miles of varied terrain and endless shifts...and a few crashes. So far so good!
