Description

Less is more.

When SRAM first introduced serious mountain bike components, it caught a certain juggernaut sleeping on the job. This, thankfully, pushed the industry to the high standards that we enjoy today. Sram hasn't let up either -- proof being the SRAM XX1 drivetrain and this GXP Crankset with 156 Q-factor.

As a whole, XX1 works as an efficient machine -- each piece engineered for precision and seamless execution. Individually, these components play a vital role in making this group the trendsetter that it is. The XX1 Crankset sets itself apart with its game-changing design and the Zen-like simplicity that comes with running a single chainring. The functionality, Q-factor, and compatibility offered by XX1 make it a standout component.

Carbon arms are mated to an aluminum spider for a lightweight single-ring setup interface. The X-SYNC chainring is designed for maximum retention, with each tooth CNC-machined to support the inner and outer links. The machining process provides a variable thickness from tooth-to-tooth, so the chain and chainring lock together as you pedal.

However, the locking of the two doesn't inhibit pedal efficiency, while liberating the drivetrain from front derailleurs and chain guides to keep the chain in place. Sram even goes as far as to say that you have a better chance of dropping your chain with a front derailleur than you do with the XX1 crank and chain combo.

The new chainring's 76mm bolt circle diameter also sets it apart from others in the SRAM catalog. This diameter emanated from a functionality standpoint, not as an afterthought of the new, universal spider shape. Its design makes it simple to remove the chainring for maintenance or ratio changes. Gone are the days of finagling the chainring off the spider -- just unscrew the bolts, move the chainring off, and have the replacement on in minutes. Even better, SRAM has created six different chainring sizes that are compatible with the XX1 spider. Now, you can dial-in your range to match the trail, beforehand or on-the-fly.

The Sram XX1 GXP Crankset has a 156 Q-factor, and comes with Black crank arms, a Silver spider, and a Silver chainring. It's available in 170 and 175mm crank arm lengths and comes with either a 30, 32, 34, 36, or 38 tooth chainring. Many frames are limited to a 32t middle ring. If you’re unsure, please check the manufacturer’s recommended chainring spec to avoid compatibility issues.
