Optimized for performance

SRAM is always pushing the boundaries of what components can do. Whether it be lightweight cassettes or burly chains, SRAM makes components that are made to be dragged through the mud and come out ready to do it again the next day. Continuing this spirit of innovation is SRAM's new XX1 group. With 11-speeds, the group works flawlessly for all disciplines of mountain biking, with the most indispensable feature being the XX1 X-DOME Cassette.

At first, the cassette body might have you puzzled. Where's the lockring? In order to make room for the 11th sprocket, SRAM eliminated the lockring in favor of its XD driver body. With the cassette threading at the base of the freehub body, it creates a stabler connection between the hub and the cassette. And by using the same installation tool that SRAM has relied on for years, this seemingly complicated cassette is actually easier to maintenance than any 10-speed. Though you may find yourself marveling at the XX1 design, its engagement and mud clearance outshines its looks. The single-unit X-DOME body provides the massive, 10-42t gear range an evenly spaced orientation for precise and consistent shifting efforts -- not to mention an ample range of gears to conquer any terrain.

It's important to note that the XX1 cassette requires the use of a distinct freehub body. However, on a bright note, SRAM estimates that its new XD driver body is around six to eight grams lighter than a standard freehub body. For now, the XD driver body is available from three sources -- SRAM, Mavic, and DT Swiss, so you still have top-tier options for a new, XX1-compatible wheelset.

The SRAM XX1 X-DOME Cassette is available in a 10-42 range and is only compatible with the SRAM XD driver body. Manufacturers currently offering freehubs compatible with the XD driver body include SRAM, DT Swiss, and Industry 9.

Very cool, Gear Range is Adequate

  • Familiarity: I've put it through the wringer

Perfectly adequate range for straight MTBing, but you''ll miss a bit on the top end of the range with a 32-tooth chainring. So don't expect to keep up with a fast group on the road. Also, beware you get the right tool with adequate inside clearance if you have a 12mm thru axle, and torque to spec, else you will get nasty creaking.


By SRAM MTB. Cool if you want to know the back story of XX1.

SRAM XX1 first ride and longterm test

By Mountain Bike Rider (MBR) magazine. This really is just a SRAM marketing video. It is a fun watch and there is some interesting information about the groupset.

Great Ratios

The gearing was well thought out. I rarely run out of gears. The 1x11 set up feel super efficient and I feel like I am always riding in the sweet spot. I love not needing to shift up front to keep moving forward.

Love it

  • Familiarity: I've put it through the wringer

This cassette is beautiful, all machined from the same piece of metal. It looks really good and is very light. The only thing I noticed the first few rides I took on it is that I felt like I was missing some gear ratios that I was used to. I ride with a 32 tooth chain ring up front and on long climbs I felt like I was in too hard or too easy of a gear. Now I am used to it and my legs have adapted so I know the ratios better and love it once again. Don't be discouraged if you aren't instantly faster. Once you adapt to it will come. If you have any questions about the XX1, I would be happy to talk to you about it.
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.

Sexy Machining, Maybe Gen 1 Issues

When you look at this cassette, it is amazing. I beleive the 10 smallest rings are made out of one chunk of alluminum, and the big ring is attached. Though maybe all 11 are the same piece. I have an enduro/all mountain/freeride style, and the gearing on this is schweet. i've never felt like i needed a bigger or smaller ring. if you were riding cross country, you'd want a bigger ring than the stock 32 up front.

After the derailleur is dialed in, shifting is NEARLY flawless, though normally it really is perfect.

I recently went on a dusty, 50 mile ride. during the second half, the chain and cassette would make a creaking sound when i was climbing in the big ring. it was an exceptionally dusty ride though. I just wonder if maybe the chain is cross-loaded too much. time will tell.

currently i'm psyched on the whole system, and it suits my style perfectly.

The BEST DRIVETRAIN on the market

It is crazy how large this cassete is, it dwarfs the front chain ring, but it is truly machined perfection.

I made the switch to XX1 this year (2013) and I am in love, I have been a long time X.0 user and have always thought the SRAM solution was unbeatable. But getting rid of the front derailleur and having such a wide range of gearing options in just 11 gears is absolute perfection. I can't imagine ever going back to the old system.
