Force 1 X-Sync 11-speed Chainring

SRAM’s Force 1 is its cyclocross-specific 1x11 group. As you might expect, SRAM took the best of its mountain groups and crossed them with the best of its road groups to create the ultimate tough, lightweight, element-proof drivetrain. At the heart of this system is the Force 1 X-Sync 11-speed chainring.

Borrowed from SRAM’s top-shelf 1x mountain group, XX1, X-Sync technology is what makes the single ring up front possible without any kind of front derailleur or chain keeper. The tall, square-edged teeth engage the chain sooner than standard teeth. They are taller, but sharper and narrower to move the chain efficiently and minimize deflection. SRAM also included mud-clearing recesses to keep the inner links and rollers clear of debris, so you’ll finish the race with the same number of gears that you started with.

  • 1x chainring for any pedaling on the 11-speed menu
  • X-Sync chainring technology for a confident hold on the chain
  • Mud-clearing recesses shed excess crud that could wreck your fun
  • Ideal for gravel and cyclocross, but serves road-riders equally well
  • Item #SRM000W

Super happy knees

Familiarity:
I've used it once or twice and have initial impressions
Fit:
True to size

Knees are happy, easy install, comes with bolts what more is there to say? I swapped out my 42 for this in 38 for more "gravel" rides over CX races. Did an epic ride with tons of bumps/baby heads and zero issues with chain drop. Also compatible with my Power2MAX NGEco power meter.

It’s a chainring, does exactly what you expect of it.

Perfect

I got this as a second option for my cyclocross bike when I am riding mostly on the road. These are easy to swap out and keep your 1x simple. Works as expected. Love Sram.

I have found that when I pair this with a 11-36t cassette it works well for most rolling to somewhat hilly road terrain. I am able to climb a local 17% incline with this gearing without significant trouble, although the incline is only stretched out over 0.2 miles. It's doesn't give the gear selection of a 2x but I really like the 1x setup for my use. If you are a strong climber this chainring should work for you. I also pair this chainring with a 11-42t cassette for gravel roads with a significant elevation gain and it works well it that condition too. I am using this setup for the only bike I own; a gravel bike. It's as close as I can come to 1 bike doing it all.

great ring. a little pricey but overall it does what it's intended to do.

Not threaded for hidden bolt

The 38 tooth chainring is not threaded for the hidden bolt on my Sram CX1 cranks. So this did not work for me. The stock chainring had one hole which was threaded, and you would push a one-sided bolt in. This one was not, and with the bolt hole behind the crank arm, there is no way to get both sides of a standard chainring bolt on there. Not sure if other sizes are threaded.

Did you work this out? I'm having the same problem and the nut which is supposed to seat in the chain ring hole just spins.

From the picture it looks like the grey one has threads on one of the bolts and the black one does not. Is this the case?

Just put the back side of the chainring bolt in the outside of the hole you plan to use for the hidden bolt position. Insert the bolt from the back (inner) side, install all other bolts as normal. Sorted. If that doesn’t work, take the spider off, install the ring, reinstall the spider. Sorted

gear options

Familiarity:

1x gravel gearing can be tricky. Living in mountainous areas requires going with a smaller ring up front, especially if you are adding packs to the bikes for longer trips. I went with a 38t X-Sync ring, along with an 11/42t PG-1130 cassette for plenty of climbing gears. The X-sync ring bolts are pretty tough to loosen up, due to loads of locktight used during assembly. Not the easiest ring to install.

Sram's narrow wide chain ring design is the best out there. Their design try makes a difference and will keep your chain on when others will jump off. If you have a sram crank, then stick with a sram chainring.

1X Sync ring

Works perfect with my Campagnolo 10 speed drive system on my cross bike in all conditions.

Holy chain retention batman

Familiarity:

In a nutshell, X-Sync lives up to all its hype. I'm running Force 1 on my cross bike, and have taken it out on trails that it really has no business being on. This chainring hasn't skipped a beat through all manner of rocks, roots, and generally jarring terrain. Not even a hint of an almost chain drop. Which is awesome.

A must have.

After several dropped chains on gravel roads and CX races, I made the leap to 1x. No more dropped chains for me! Sram's x sync tooth pattern with the matching chains are brilliant.

38T is my choice for SSCX in Utah

Familiarity:
I've put it through the wringer

I have a 38T and a 42T chainring for single speed racing in Utah. With the 38T my range of rear cogs goes from 16T-19T based on chain tension, the length of my drop out slot and the tolerance of my rear tire and frame. 80% of the time I race on 38T/16T, leaving my quick release at the end of my drop out. I use the 19T on two different hilly courses here in Utah and whenever its snowing. There was one race I was tempted to run 42T/17T because it was so flat and my chain would be too slack if I ran 38T/15T. This season I also switched out my rear 8.4 V-Brake for an Avid Shorty Ultimate because it's much quicker and easier to adjust each time I switch out my cogs. I still rock the V-Brake up front.

Good enough for. J POWs bike

Nice set up

Nice

did you use the supplied bolts?

Why does the tech section, under the heading of number of rings, say 2?

>Rating:

Does the FORCE 1 chainring fit on on Rival1 spider/crankset? BCD is the same but will the bolt holes work with the hidden bolt drilling on FORCE?

Hey Andrew! These rings will work just fine with your Rival crankset, provided you're running the same BCD. Feel free to reach out yo me directly at jdraper@backcountry.com if you have any more questions!

>Rating:

Does this come with chainring bolts or do I need to buy them separately?

This will not come with chainring bolts so you will need to have those separately. Please contact us if we can help with anything else!

>Rating:

Is this ring compatible for 5-bolt 110bcd shimano cranks? (6700)

>Rating:

Backwards compatible with SRAM Red 10 speed crankset? I've heard through the grapevine that it is.

Is there a guide to select a size? For example advantages of 38t vs 42t?

http://www.sheldonbrown.com/gears/ The gear calculator will let you calculate things like gear ratio's, meter development, max speed @ rpm. This is what I use to justify my gearing, which is individual to how you ride and your area terrain. Let us know if you have any more questions!

Lower gear ratio for the 38T=easier pedaling. Really depends on terrain and your riding ability as to what you would need. Check on SRAM's website they have good info on the 1x setup.
