Description

Keep your drivetrain and legs in sync

When SRAM set out to create the ultimate one-by cyclocross group, it looked to its well-loved mountain bike components for inspiration. The derailleur is a hybrid of all the best parts of its road and mountain groups and to that end the chain rings needed to be equally as impressive. The Force 1 X-Sync 11-speed Chainring features SRAM's X-Sync design to ensure secure shifts with no slip.

The X-Sync technology was originally developed as in integral part to SRAM's XX1 mountain bike group. The teeth on the chain rings are cut with a tall, square edge which engages the chain earlier than traditional triangular teeth. They are effectively taller, but sharper and narrower which help to move the chain efficiently and minimize deflection. Additionally, mud-clearing recesses were designed into the chain ring so that inner links and rollers stay clean. And although initially designed for muddy trails, if you race 'cross anywhere but Southern California, you know that being able to shed mud efficiently is paramount to keeping your drivetrain working for the duration of your race. There is nothing worse than being reduced to 3 working gears with 4 laps to go.

SRAM's Force 1 X-Sync 11-speed Chainring is available in five sizes: 38, 40, 42, 44, and 46 tooth.

    It works

    Familiarity:
    I've put it through the wringer

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

    >Rating:

    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!

    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.

    >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!

    Works as expected

    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

    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.

    Holy chain retention batman

    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.

    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.

    >Rating:

    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.

    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.
