SRAM's pursuit of seamless and simple component integration shows it continually innovating the component industry -- case in point being the XX1 group. As a whole, XX1 works as an efficient machine, but individually, each component plays a vital role in making this group the trendsetter that it is. The XX1 BB30 Crankset sets itself apart from others with its game-changing design and the Zen-like simplicity that comes from running a single chainring. The functionality, Q-factor, and compatibility offered by XX1 make it the standout component in the new SRAM arsenal.

Carbon arms have been mated to a redesigned aluminum spider for a lightweight crank arm that doesn't require a finessing of parts to make an optimal single-ring setup. The X-SYNC chainring is designed for maximum chain control, with each tooth being CNC-machined to support the chain's inner and outer links. The 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 upfront. What we love most is the liberation from chain guides in order to keep the chain in place on rugged, chain-slapping trails. 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 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 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.

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

This BB30 specific crank has a 168 Q-factor to accommodate those who prefer a wider tread. The SRAM XX1 BB30 Crankset 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 a 32 tooth chainring.

can you get this product with 175mm arms and a 168q-factor?

No more 175mm length in this and you don't...

No more 175mm length in this and you don't offer the X01 version. Are you getting either in stock any time soon?

In an interest to give you more gearing options, we have actually changed SKUs on these cranks to SRM0546 and have several different chainring sizes available.

Please let us know if you have any other questions.

Hi Kyle - why are the new SKUs significantly more expensive for the same item?

Can I use this with the X01 derailleur,...

Can I use this with the X01 derailleur, X01 cassette, and shifters?

You certainly could and these would work perfectly.

Enjoy the ride!
