UPDATED: Crank weights, Q-Factor and BB weights.

SRAM’s 2×10 drivetrain concept has officially taken over their groups, and the X0 is the do-all lineup that SRAM says is aimed at all types of riders, from XC to All Mountain to Freeride to Downhill.

To prove it, they’ve been testing the parts under riders like Jeremy HK and Heather Irmiger on the cross country side all the way to Sam Hill and Steve Peat on downhill rigs.  Now, we get the benefit of all that testing in a system that’s light and capable.  And we get it in colors: Blue, Gold, Red and Gray/Silver.

We’ve posted pics of all these parts on the bikes, and here are the official press photos compiled into nice little montages, just for you. Jump on in for all the glossy studio shots and full specs and weights for each component in the SRAM X0 2×10 group…

All of the 2×10 cranks will get SRAM / Truvativ’s X-Glide shifting that was introduced on XX, which is basically a set of specific 3:2 (or 1.5:1 depending on what you’re reading, same thing) gear ratios with specific ramps and pins that are lined up exactly in sync between the big and small rings.

The X0 cranks have 26/39 and 28/42 gearing for the 2×10, and as promised there will still be a triple option for the XO (and X9 and X7, too) with 22/33/44 gearing.  Rings are CNC-machined, 7mm-thick aluminum. The crankarms are carbon fiber and SRAM says they’re strong enough for “trail” riding.  There’s a new GXP Bottom Bracket System featuring Gutter Seal Technology, and the crank spindle will be available for PF30, BB30, GXP and GXP PF
configurations. (PF = Press Fit)  Weight is something we’re working on getting, the info they’ve sent has it misprinted at 198g, which is crazy. Official claimed weights are 736g for BB30 and 790g for GXP.  The X0 crankset, like the X9 and X7, will only be available in standard Q-Factor (no options like on XX).


If you’re using the standard GXP bottom bracket, it’ll come with the Team Edition.  According to Truvativ’s website, it weighs in at 121g, with a ceramic option at 110g.  SRAM’s press kit on the new XO didn’t list weights for the BB, and the only visible difference between this version and the existing Truvativ GXP Team is the color and the slight tapering on the outside edge of the cups, meaning this new version might be a couple grams lighter.

The GXP PF option is designed around 92mm BB shells and weighs in at 83g for ceramic bearings and 94g for standard. BB30 bearings are 56g ceramic / 64g standard, and the BB30 PF is 83g ceramic / 91g standard.


  • SRAM’s 2X10 and 3X10 1:1 Exact Actuation, will work with any Exact Actuation rear derailleur
  • The first patented adjustable trigger shifter with aluminum push trigger /composite release trigger
  • MatchMaker X and Matchmaker upgradable
  • 232g (2×10)

The Avid XO brakes replace the Elixir CR Mag and move to an aluminum body for better impact resistance, but they keep the same weight at 333g per set (front, 160mm rotor, post mount).  They have a detented contact adjustment, tooled reach adjust and there will be carbon fiber and alloy lever options.


The Calipers have a new 2-piece forged body that supposedly dissipates heat better with an open, two-piston system.  Banjo adjustment is tooled, and the design is said to improve ease of bleeding and service.  They’ll come with organic pads.


The rear derailleur comes in short, medium and long cage options and is set up to accommodate the 36T big cog on their 10-speed cassettes.  The carbon fiber cage houses sealed-bearing pulleys, and the whole thing weighs in at 190g.  It’s made up of a mix of stainless steel, forged aluminum and carbon fiber.


The front derailleur uses a steel cage, aluminum clamp and weighs in at 130g.  It’s made to work with a chainstay angle of 66º to 69º and comes in versions for High Clamp / Low Clamp (31.8, 34.9, 38.2),Low Direct Mount (S1, S3) and High Direct Mount.  Cable routing is for top or bottom pull.

sram-2011-2x10-x0_cassette-2The XO 10-speed cassette will initially only come in an 11-36 tooth size.  Weight is 235g, and it uses an aluminum body and lockring with a steel back plate and 36T cog.


The PowerChain PG1091 weighs 257g (114 links) and uses chrome-hardened hollow pins and a tool-free PowerLink connector.

Pricing for the group is TBD, and it should be available this Summer.
