SRAM’s revolutionary X-Sync technology has trickled down to a more affordable group. GX is their newest MTB group and it spans everything from a 1×11 with X-Sync ($564 USD trigger, $573 grip) to a 2×10 ($511 USD trigger) or 2×11 ($661 USD trigger, $677 grip). It’s an all-encompassing platform, for everyone, everywhere.

The 1×11 system will hit retail shops in July, with the 2×10 in June and 2×11 in August. Check out specs for the GX 1×11 with X-Sync below and see more details for the other offerings at SRAM.


The SRAM GX crankset delivers consistent performance every time out. Featuring SRAM’s 
X-SYNC™ tooth profile, the GX crankset is engineered for complete chain control. Each 
tooth’s thickness is CNC machined to work seamlessly with the chain’s inner and outer 
links. And with five available chainrings (30-32-34-36-38), you can personalize your 
gear range to match the way you ride.

FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that’s extremely light, durable and equipped with SRAM’s super wide 10-42 gear range that’s a perfect fit for any ride. The open design similar to our X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.

The SRAM GX X-HORIZON™ rear derailleur is engineered for smooth, reliable shifting action—from the larger upper pulley offset to the 12-tooth X-SYNC™ pulley wheels. By eliminating unwanted chain movement, X-HORIZON™ shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with CAGE LOCK™ technology, wheel removal and installation are easier than ever.

    Might be enough to put me back on SRAM, since I MTB about 10 times a year I just want a system that works well together and isn’t the piecemeal junk I have now that never seems to work well together.

  • Dobry

    Love trickle down technology. Thanks SRAM!
    And thanks for putting the pricing in the first paragraph.

  • Love the trickle down names too! First SRAM follow our lead with CX1, then Specialized with AUDAX and now SRAM again with GX. Good to know we are on the leading edge of product naming! ;)

  • Will the Force22 double tap road shifter/brake lever work with the GX 1×11 set up? Exact Actuation™ and X-Actuation™ sound like the same thing (1:1 cable pull) but it seems like they never really are up front about total compatibility between road and MTB.

    • Eric Karacsonyi

      SRAM’s road and Mtb gear usually works together. Both are 1:1. No promises on 1×11 though.

    • Josh Direen

      Exact Actuation and X Actuation are not the same. Exact Actuation is what they use for everything except for 11SPD mountain, X Actuation is specific to XX1/XO1/X1/GX. However, cassette spacing on all 11SPD stuff is the same. So, you could run a road shifter with a CX1 derailleur and an XX1/XO1/X1/GX 10-42T cassette. You could also use a Type 2 or Type 2.1 XO, X9 or X7 derailleur, as they are both Exact Actuation, but due to the traditional pulley placementon X7/X9/XO, shifting on the 10-42T cassette wouldn’t be that great.

      • Ok, that makes sense. Thanks for breaking it down for me.

  • Eric Spinney

    Proper Drivetrains at cobbled together pricing. I can get into this!

  • Frank

    Am I missing something – why are MTB cranks usually not offered in 172.5mm?
