Item # SRM0544

Simple and efficient.

SRAM's objective for XX1 was simple -- improve a seemingly stagnant mountain bike component market. As a whole, XX1 works as an efficient machine -- each piece engineered for precision and seamless execution. However, the standout piece of the puzzle has been proven to be the XX1 GXP Crankset with 168mm Q-Factor. Essentially, it sets itself apart with a revolutionary design and a Zen-like simplicity.

Carbon fiber arms have been mated to a redesigned aluminum spider for a lightweight crank arm that doesn't require a finessing of parts in order to make an optimal single-ring setup. The X-SYNC chainring is designed for maximum chain control, with each tooth being CNC-machined in order to support the chain's inner- and outer-links. This machining process provides a variable thickness from tooth-to-tooth, so the chain and chainring essentially lock together as you pedal. However, the locking of the two doesn't inhibit pedal efficiency, and it eliminates the commonplace ailments associated with running a single-ring up front. Additionally, this system provides you with a liberation from chain guides. SRAM even went 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 76 bolt circle diameter 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 either maintenance or ratio changes. Gone are the days of finagling the chainring off of the spider -- just unscrew the bolts, move the chainring off, and you'll have the replacement on in minutes. Even better, SRAM has created six different chainring sizes that are compatible with the XX1 spider. Now, you're able to dial-in your range to match the trail, either beforehand or on-the-fly.

And though the XX1 crankset is designed to work optimally in tandem with the XX1 group, you're able to use the crank and a 10-speed chain in order to enjoy the benefits of running a single-speed or one-by-10 setup.

The SRAM XX1 GXP Crankset with 168mm Q-Factor is available in the color Black and with either a 170 and 175mm crankarm length. Additionally, each length is available with your choice of 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.

  • With the removal of spider, cranks are compatible with SRAM Direct-Mount chainrings

Unanswered Question

Will this crank work with X01 shifter and rear derailleur? Also, what is advantage of this version versus the direct mount XX1?

Can the spider be removed to accept direct mount chain rings from SRAM?

Hi Derrick,

You can remove the spider to accept XX1 direct mount rings.



How can I make this SRAM XX1 fit on my bike that currently has a setup consisting of a BB91 bottom bracket w/ Praxis Works sealed cartridge. Its a 2014 Fuji Tahoe 1.5 27.5.

You will need a bottom bracket that is designed for a GXP crankset. If you have Sram cranks you are taking off, chances are that it will work. If its a Shimano crankset, you will need to replace the BB as well.

Does this crankset include a chainring and bottom bracket?

Hey Nick,

It does come with a chain ring but you need to get the BB separately
