SRAM’s new 1×11-speed drivetrain takes what the company learned from their 2×10 XX drivetrain a step further. Further simplifying the shifting operation, minimizing weight, and increasing drivetrain stability by integrating chain control technologies into the system. We are certainly looking forward to putting SRAM’s XX1 to the test on our local trails.

Here’s what SRAM has to say about their new XX1 group: 

SINGLE-MINDED PURSUIT 

Driven by a cutting-edge, single-ring carbon crank and seamless component integration, SRAM 1X drivetrain delivers flawless chain management and faster, more precise shifting. But the relationship between XX1 components goes far beyond fitment. From the X-HORIZON? rear derailleur with TYPE 2 technology to the super wide range 11-speed 10-42T cassette, each component is designed to function synergistically with the others, achieving what no other 1X drivetrain has before.

XX1 Cassette

Ranging from 10- to 42-teeth, the 11-speed X-DOME? delivers an incredibly wide gear range while maintaining even, optimized steps. The single-unit cassette combines with the XD? driver body for a superior connection to the wheel. Available October 2012.

  • 11-speeds (10-12-14-16-18-21-24-28-32-36-42)
  • Bearing design and ratchet mechanism steadied by XD driver body
  • Creates more stable hub connection 
  • Gear steps optimized across entire range 
  • Wheels equipped for XD driver body available from SRAM and DT Swiss 
  • XD driver body is 6-8g lighter
  • Weight: 260 grams 

XX1 Crank

Developed for maximum chain control, each tooth’s thickness is precisely CNC-machined to support the chain’s inner and outer links perfectly. Six available chain rings (28-30-32-34-36-38) allow you to tune your gear range to match your terrain, wheel size and riding style. Each X-SYNC? chain ring fits a single, universal spider?allowing you to change rings without removing the light-weight carbon crank arm. Available October 2012.

  • New tooth profile alternates thickness by inner and outer links, providing maximum chain control
  • Carbon arms with forged aluminum spider
  • CNC-machined rings (28-30-32-34-36-38)
  • New spider design allows for easier ring changes
  • Wide/narrow Q factor cranks for BB30 and GXP
  • Weight: 650 grams with BB (approx.)

X-HORIZON Rear Derailleur

With its “horizontal parallelogram” design and pulley offset, X-HORIZON? keeps the chain gap constant across all 11 gears, providing fast, precise shifts. By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting. ROLLER BEARING CLUTCH? technology reduces bounce and chain slap. CAGE LOCK? technology makes wheel removal and installation easier than ever before. Paired with the XX1 shifter, the X-HORIZON RD forms the backbone of X-ACTUATION? technology for unbelievably smooth shifting action. Available October 2012.

  • 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 (approx.)

XX1 Grip Shift

  • SRAM 1X11 X-ACTUATION? for precise and dependable 11-speed performance
  • SPEED METAL? shift indexing
  • ROLLING THUNDER? ball bearing technology
  • JAWS? lock-on grip technology
  • Carbon cover
  • Full Gore Ride-On cable system
  • Available October 2012.

XX1 Trigger Shifter

  • SRAM 1X11 X-ACTUATION? for precise and dependable 11-speed performance
  • Multi-adjustable trigger shifter
  • MatchMaker X compatible
  • Carbon cover and adjustable carbon pull lever
  • Full Gore Ride-On cable system
  • Available October 2012.

XX1 Chain

The XX1 chain represents the latest breakthrough in a long line of precise, light-weight chains from SRAM. It’s designed to deliver the greatest strength and reliability to a drivetrain that doesn’t have to make compromises for front shifts. Available October 2012.

  • New 1X11 XX1 specific chain
  • Designed for maximum strength and wear resistance
  • Proprietary link finish provides improved life span
  • 11-speed power lock
