Get direct.

SRAM's X-Sync Direct Mount Chainring features X-Sync's tall, square teeth to engage the chain sooner on each rotation for maximum control with a one-by drivetrain so the chain doesn't get bored and wander off onto your pedal spindle. The teeth also alternate between narrow and wide with mud-clearing recesses in between in order to keep a hold on the chain even during deflections on mucky trails.

The quick interchangeability of direct-mount rings mean you can stock multiple sizes to adjust your drivetrain for any given course or terrain. Regardless of which size you're running, the chainring is finished with a built-in forged aluminum spider that sticks to the lightweight theme while carefully preserving the direct-mount crank arms' gains in efficiency.

  • Quickly adapt your chainring to changing terrain
  • Tall, squared tooth profile sheds mud and holds tight to chain
  • Aluminum spider increases structural integrity

If I have a 1x11 GX-1000 crankset, PF30, 28t on a Specialized Comp 6fattie, which offset do I need to swap the 28t with a 32t? The chart above confuses me because I don't see the GX crankset in the options and I'm not replacing a spider and chainring, just replacing the stock DM chainring. Thanks!

Hey Steve, your Specialized Stumpjumper 6Fattie is going to have Boost hub spacing, so you'll need the 3mm offset for the Boost spacing! Let me know if you have any questions - my direct line is 801.204.4547 or you can email me at cojohnson@backcountry.com. Cheers, Connor

Love buying from backcountry

    Best pricing shipping and customer service out there I ordered this chain ring but I had ordered the wrong offset even though I installed it on the bike they gave me a full refund and sent me what I needed I am never disappointed when dealing with backcountry for my cycling needs and they also have really quick shipping included with your purchase

    Awesome.

      Direct mount is a huge improvement over spider style cranks. I have broken many cranks at the spider, but with this it makes that issue a thing of the past. This chain ring has great chain retention, and was very easy to install.

      Good but...

      • Familiarity: I've used it several times

      It is a chainring, it does what it is supposed to do well. I consider myself an ok home mechanic, I went to change the chainring, such a pain compared to the previous SRAM 4 bolt system where you remove 4 bolts, slip ring over crank, put on new ring (adjust chain if necessary) and tighten four bolts. With this you must remove the crank, can be daunting to a newbie, easy to loose washers or put them on incorrectly. Now the worst bit, trying to remove tightly treaded bolts when the spindle is very close to them. It came with my Canyon Spectral, would not buy it, back to 4 bolt design for me.

      Stiff and quiet

      • Familiarity: I've used it several times

      The direct mount is simple and easy to install. The ring is stiff and keeps things quiet while pedaling. So far I have not dropped a chain due to the narrow/wide design of this chain ring

      Narrow-wide

      • Familiarity: I've put it through the wringer

      The SRAM 1x11 system is outstanding. I love the simplicity of only shifting the rear derailleur along with reduced weight and accuracy. The narrow/wide profile of each tooth mates perfectly with the XX1 chain and helps to hold the chain tight. Lessening your need for a chainguide. The X-Sync Direct Mount ring works flawlessly and is highly recommended to complete your 1x11 group.

      My 2016 Specialized Stumpjumper Carbon comp has Sram S-1250 PF30 crank. I'm converting to 1X with the X01 cranks and this direct mount front chainring. Do I need the 0mm or 6mm offset?
      Thanks.
      -Ron

      For X01 cranks, if you have a GXP bottom bracket you will need 6mm offset. If you have a BB30 or a PF30 bottom bracket you will need zero offset.

      There's a big chart up there with all the sizing info. For PF30/BB30, X01, any chainring size, use 0mm offset.

      X-SYNC Direct Mount Chainring

      • Familiarity: I've used it several times

      Great chainring! Works great, really tough, and looks awesome.

      Light weight.

      • Familiarity: I've used it several times

      Its amazing how much lighter this thing is compared to the spider. Once all the chainrings on my other bikes wear out I will only purchase direct mounts. Very stiff and easy to install. Would recommend!



      Pic of ring installed. Looks so clean!

      Light weight.
      Unanswered Question

      I have an X1 1400 crankset on my 29+ with boost. I want to upgrade to the x-sync direct mount chainrings. My bb is a pressfit gxp bb92 so it makes sense to order the ring for boost with a 3mm offset however I have heard the sram reference chart may not be accurate. I want to preserve my 52mm chain line. The Thanks.

      LIGHTWEIGHT, NO FLEX

      • Familiarity: I've put it through the wringer

      I like that this chainring does not require a spider. It almost feels as though you are more connected to the wheel. Very solid and any flex is imperceptible.

      Watch your chainline. Zero offset was recommended for my setup, but the 6mm offset best preserved the original chainline. (My setup is X01 with BB30)

      No need for a spider

      • Familiarity: I've put it through the wringer

      Get rid of the spider on your Sram crank and install a direct mount. This set up is lighter and extremely stiff.

      How long does this chainring last before it gets the 'fingernails down the chalkboard' grinding of the standard xx1 chainring?

      Hey Howie,



      This chainring will last about the same time as the XX1 chainring. As for the "fingernail down the chalkboard" I'm not sure what that would be caused by other than a dry chain, or dirty drivetrain possibly.

      It is normal to hear the chain coming off the chainring. Frankly it is a bit of a grinding sound. The narrow-wide design holds the chain on pretty tight. (I have never dropped a chain.) My 1X chainrings do not show significant signs of wear, even at +1,000 miles.

      Replace and reduce

      • Familiarity: I've put it through the wringer

      When (or if) your XX1 or X01 ring wears down, drop some weight and boost the aesthetics of your ride with the X-Sync direct mount ring. It mounts directly to the arm on any X01 and XX1 crank, and some previous generation X0 cranks. If you have a BB30 crank, you'll need the 0mm offset variant, and if you have GXP cranks, the 6mm offset is the ring for you. If your bike has the newer Boost 148 rear axle spacing, you'll want the 3mm offset ring.

      Replace and reduce

      "... if you have GXP cranks, the 6mm offset is the ring for you."

      Are you sure? I have GXP and was told by my bike manufacturer (2016 Trek Stache 7) that the 3mm offset was the correct one.

      One of he best on 1X11 chainrings

      • Familiarity: I've put it through the wringer

      The ultimate solution for anyone that wants to run anything smaller then a 30 tooth chain ring on their Sram mtn crank. SRAM has specifically designed a wide-narrow tooth profile that keeps the chain really snug, allowing you to leave your chain keeper in the garage. I simply love this chain ring.
