X01 Groupset – the official release

by Dave Anderson 19

The worst kept secret of the year X01, the trickle down of 1×11 gearing from SRAM’s XX1 groupset, is now official.

Small differences have had to be made to bring the price down to more affordable levels. X01 cranks feature a 94mm BCD instead of XX1’s 76mm which means no 28 tooth chainring, the shifter has an aluminium rather than carbon cover, the chain has solid outer plates and the cassette comes with a black ‘coating’ claimed to extend its life but at less cost than the XX1 equivalent.

With the number of 2014 bikes already appearing with X01 options it’s bound to be a popular choice next year, but with the previously seen X1 crankset now replaced within the groupset by an X01 carbon armed version, will we see the 1×11 option trickle down to X9 and beyond? Only time will tell.

Availability is officially from mid September 2013.

Here’s SRAM’s official words on the matter…


SRAM 1X™ is the only one you need: less weight, better chain control and the ability to sync up with any riding style. Our 1X drivetrain philosophy focuses on optimizing how components work together—crank to ring, tooth to chain, shifter to derailleur, derailleur to cassette, and cassette to wheel. No matter where you ride, no matter what you’re up against, SRAM 1X takes you further.


Building the next generation of single chain ring drivetrains takes more than a few well-made components—it takes components made perfectly for each other. The result: flawless chain management, lower weight and faster, more precise shifting. The same spider works with all 6 ring sizes for faster gear tuning. The teeth on each ring of the crankset use X-SYNC™ design to hold the chain better. The X-HORIZON™ Rear Derailleur stops chain slap and ghost shifting. And the 11-speed, 10- to 42-tooth X-DOME™ Cassette keeps each gear step exactly even.


The SRAM X01 drivetrain carries on the tradition of SRAM’s championship-winning 1X™ philosophy—all the way down the mountain. The setup is simpler. The drivetrain is lighter. And the shifting is fast and solid. Bottom line: X01 is the right one for any terrain, every time. RELENTLESS.

Those technologies in SRAM’s own words…


This rear derailleur’s “straight parallelogram” design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.


A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire chain ring, perfectly mirroring the chain’s inner and outer links for maximum control.


The XX1 Chain has 4 times the elongation (wear) resistance to our other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The XX1 Chain lasts longer and is just as strong.


XD™ is a new cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.


Developed specifically for SRAM 1X™, X-ACTUATION™ keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.


With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.


ROLLER BEARING CLUTCH™ technology eliminates derailleur bounce and chain slap without sacrificing precision.


Full metal, 11-speed indexing keeps shifting crisp and precise with Grip Shift.


Three rows of ball bearings provide zero friction or play—reducing the force needed to shift and promoting long-term performance under all weather conditions with Grip Shift.


Once the Grip Shift shifter and grip interlock securely, forged aluminum clamps on either end reinforce the assembly by locking tightly to handlebar.


X-DOME™ technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.


Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.


GXP’s Gutter Seal design cuts friction, durability and weight—improving both feel and performance.

  1. So much marketing waffle in that pick of the bunch ROLLING THUNDER!

  2. 1070 euros, or about £930. Not exactly the XT price they were aiming for…

  3. On bikediscount the XX1 crankset is quoted as:
    MSRP* 293,45 €

    The new one is above quoted as:
    Price: €287

    Disappointing, I hope the real world prices end up being more realistic.


  5. Looking good, will have to wait and see what the Oz$ price comes in at. Heard plenty of happy XX1 users. As for the XT it might have been what they were aiming at but X0 always came in somewhere between XT/XTR recently.

  6. Yeah, need to wait for real world prices… But if the cassette price doesn’t work out a lot less, I’m out.

  7. Exactly. That sort of outlay every 6 months or so for a new cassette makes it unsustainable.

  8. I’ll stick with my ghetto xx1 type setup. XT, clutch, Wolftooth….

  9. You and many others chunky i would say.
    Whilst the tech has trickled down, the prices need to do a bit more trickling imo.

  10. and what’s q-factor?

  11. Every 6 months Mal-ec??!

  12. Hmm, gripshift option has suddenly got my interest

  13. I hope it lasts longer than the new X9 kit. Gotta agree with Mal-ec on this one. 6 months is what I get from X9 and am now having to look at new chain, cassette, front rings and rear mech given how much play there is in it with the jockey wheels resembling Ninja stars! Shimano definitely lasts longer. I’d previously ridden older generation X9 with Gripshift and it lasted longer too despite doing approx double the mileage. As for the press fit BB’s, mine lasted 6 weeks before the squeaking and play started.

  14. Oh and by worn out I mean being at the chain slipping, sharkfin teeth stage that signals that you have only a couple of rides left before you will experience the inevitable knee or testicle / stem interface that comes with a worn drivetrain! I reckon if I was exclusively using my SRAM equipped bike I would have been lucky to get three months out of the drivetrain. Given that I’m not riding every day, that’s not great.

    359 Euros for a cassette? Cue hysterical laughter. That’s a lot of money for a consumable. I hesitate to say it but you could get a bike for that!

  15. Lovely kit, great marketing blurb etc, etc but have to echo the comments on the price. When did mountain biking get so damn expensive?! I could run a car for less than a high end mtb these days and buy one for a lot less as well.

  16. I cant believe how expensive it is going to be especially after all the hype of XO being XT standard. Its a real shame as I would love to use 1×11 but not at these prices.

  17. so can we use the new chainring with a normal chainset and 1×10 clutch set up?

  18. Yes you can use a XX1 and X01 chainring with a “normal” 10 speed chain, I´m using a XX1 crankset on with a 10 speed cassette with a General Lee adaptor, it runs perfect.
    The internal width of a 10 speed chain and the XX1,X01 11 speed chain is the same.
