Sram X01 – One. And Only
August 1st, 2013
Between bigger wheels and Sram’s revolutionary 1 x 11 drivetrain, the kind of bikes many of us ride are changing forever and quicker than expected… The argument for sticking with what we already have, regardless of how well it works, is one that has never stuck in the MTB industry and whether you acknowledge it or not, is responsible for the awesome machines we have today. In a year or two we’ll all laugh about how silly those little wheels and front derailleurs were, but hey, lets not jump the gun too much, here’s Sram’s X01…
ONE. AND ONLY.
SRAM 1X is the only one you need: less weight, better chain control and the ability to sync up with any riding style. Our 1X drivetrain philosophy focuses on optimizing how components work together—crank to ring, tooth to chain, shifter to derailleur, derailleur to cassette, and cassette to wheel. No matter where you ride, no matter what you’re up against, SRAM 1X takes you further…
Building the next generation of single chain ring drivetrains takes more than a few well-made components—it takes components made perfectly for each other. The result: flawless chain management, lower weight and faster, more precise shifting. The same spider works with all 6 ring sizes for faster gear tuning. The teeth on each ring of the crankset use X-SYNC™ design to hold the chain better. The X-HORIZON™ Rear Derailleur stops chain slap and ghost shifting. And the 11-speed, 10- to 42-tooth X-DOME™ Cassette keeps each gear step exactly even.
This 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.
A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire chain ring, perfectly mirroring the chain’s inner and outer links for maximum control.
The XX1 Chain has 4 times the elongation (wear) resistance to our other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The XX1 Chain lasts longer and is just as strong.
XD DRIVER BODY:
XD™ is a new cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.
Developed specifically for SRAM 1X™, X-ACTUATION™ keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.
With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.
ROLLER BEARING CLUTCH:
ROLLER BEARING CLUTCH™ technology eliminates derailleur bounce and chain slap without sacrificing precision.
Full metal, 11-speed indexing keeps shifting crisp and precise with Grip Shift.
Three rows of ball bearings provide zero friction or play—reducing the force needed to shift and promoting long-term performance under all weather conditions with Grip Shift.
Once the Grip Shift shifter and grip interlock securely, forged aluminum clamps on either end reinforce the assembly by locking tightly to handlebar.
X-DOME™ technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.
Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
GXP’s Gutter Seal design cuts friction, durability and weight—improving both feel and performance
