A ring for every occasion.

SRAM's XX1 is a fresh approach to drivetrain designs that builds on proven, and preferred, principles of established riders and racers alike. One-by setups are nothing new, but none have offered the ratio spread, chain retention, and performance driven technology that this 11-speed group does. The single front chainring, in fact, packs as much design time as some multiple-cog cassettes.

Take a look at the tooth profile, and its shape is decidedly unique. This isn't your run of the mill single-speed ring. The contours are designed to optimize the chain-to-ring interface for holding the chain on, and each tooth's thickness alternates to match the inside width of inner and outer links. No other chainring on the market does this.

Another unique feature is that the ring is threaded. You won't find traditional two-piece bolts here, the bolts thread directly into the ring. This eliminates the 'nut' for reduced weight and a stiffer interface with XX1 crank arms. Even the tabs are machined to interlock with the spider for reduced load on the bolts themselves.

The rings are only compatible with XX1 cranks and 11-speed chains. SRAM's CNC-machined alloy XX1 Chainrings come in six sizes: 28T, 30T, 32T, 34T, 36T, 38T.

Great ring!

  • Familiarity: I've put it through the wringer

Bike came with a 32, which was a bit much for Tahoe area climbs.
Put on the 30 and all is good!

Addicted to one

  • Familiarity: I've put it through the wringer

I admit it. I'm a 1-by addict. I recently switched from my 34t to a smaller 30t ring. I have no issues climbing with a 34 (and I live in PC) but I think my knees would prefer I spin more....

Excellent chainring! The tooth design eliminates chain drop, and paired with the XX1 rear derailleur, I've never so much as missed a shift.

If you're going 1-by....go SRAM.

Unanswered Question

The last paragraph says that this ring is...

The last paragraph says that this ring is only compatible with XX1 cranks. Will it bolt up to a X01 crank? I can't find anything on SRAM that says it won't but nothing says it will for sure.

Great Chain Ring

  • Familiarity: I've put it through the wringer

This chain ring is the bee's knees. Every other cog is a different shape so it forms a "lock and key," mechanism that keeps your chain from getting tossed off of your chain ring. I ride with the 32 tooth which is pretty good for all mountain riding but if you got stronger legs or focus a little more on the downhill aspect of riding you might want to go with a 34 tooth chain ring. If you have any questions about the XX1 drivetrain feel free to give me a call.

Here is my contact information: My direct line 801.736.6396 ex. 4389. Feel free call to me anytime, I?m always happy to talk about bikes or gear or the weather. Whatever works! I?m here Mon, Tues and Friday 1:30-10pm MST and Saturday 9-5:30 as well as Sunday 10-7. I look forward to speaking with you.

XX1 is top notch

  • Familiarity: I've put it through the wringer

The XX1 system is top notch and a great addition to any mtn bike. These chain rings are durable and light weight and very easy to install. Highly recommended.

Great so far

Not much to say here: it's been durable half way through the season and the alternating wide small tooth pattern holds the chain very well. I've taken some pretty rough decents and haven't dropped the chain or felt it skip.
