I would like to convert my bike into a 1x11. So I was wondering if the Race Face Narrow Wide Chain ring will interchange with the Race Face Next SL Carbon 2X10 speed cranks and go from a 2x10 to a 1x11 set up?

I looked at the info for my sram cranks to do the same and it works with it so my bet is that it would.


  • Familiarity: I've put it through the wringer

I bought this after Shae( She is great) from the bike dept at backcountry recommend it as part of the parts ( Shimano CN-HG600 11-Speed Chain,Shimano XT CS-M8000 Cassette,Shimano XT RD-M8000 Rear Derailleur, Shimano XT SL-M8000 RapidFire Trigger) to convert my baby (2016 Santa Cruz Heckler) to a 1 x 11. After a 100 miles I have not dropped my chain, some of those mile have been at bike park (mountain Creek NJ) which as some very rocky terrain. It looks good and performs like a champ, could not be happier; all done at a very reasonable price. My only regret is that i did not changed sooner to a 1 x11

I am glad to hear Shae took care of you and got you switched over to 1x11. It is the only way to ride!

1x FTW

  • Familiarity: I've put it through the wringer

Love these rings. I ran a 30T with 36 out back and now I run 32T with a 42 in back. I think it's just great. I never have lost a chain on this setup and it converts from 2x very smoothly. If you have a standard 12-36 cassette I would recommend going with a 30T unless you are very strong. That semi-granny can be nice for those long doubletrack slogs.

Great Chainring

  • Familiarity: I've put it through the wringer

Race Face makes great products and this is no exception. The narrow wide works great for a single ring in the front and fits on my cranks effortlessly.
Plus you can pick them up in awesome colors.

Works Great

  • Familiarity: I've put it through the wringer

This chainring will keep your chain on 99.9% of the time. Works great with 10 or 11 speed setups. If you are still looking for added insurance a simple top guide works great.

Simple and efficient!

  • Familiarity: I've used it once or twice and have initial impressions

I replaced the three rings on my Giant with a Race Face 32T because I only use the second ring anyway. It bolted right up and works fine with the stock rear derailleur. No other changes needed other than changing to single ring mounting hardware.

Simple and efficient!

$ Money $

  • Familiarity: I've put it through the wringer

I love the RaceFace Chainrings, they represent the best value in narrow wide rings, by a long shot. They function wonderfully and I do not hesitate to continue running them.
Other products used:
SRAM, WolfTooth, Chromag (SRAM Licensed), MRP Wave Ring.

I just wished they lasted a little longer, but that is the price you pay for a light weight narrow wide ring.


  • Familiarity: I've used it once or twice and have initial impressions

The middle 'ring on my 3x10 setup was toast, so I decided to make the leap to 1x11. This chainring works great and was able work with my (formerly) 3x crankset.

Solid componentry

  • Familiarity: I've put it through the wringer

When I converted to a 1X system a month ago, this cog was one of the crucial pieces to my setup. It has already undergone several hundred miles, and has held up admirably on the steepest and most technical of climbs, as well as a couple of races. Quality product.

Solid Commuter Option

  • Familiarity: I've put it through the wringer

I got doored on my commuter bike a few months ago which resulted in a few scrapes and bruises along with a bent chainring. I wasn't a huge fan of the stock gearing, so I decided to swap everything out. I'm using a 38t with a 9spd 11-28 cassette. I would have preferred a larger ring, but those don't seem to be available in a 104bcd and I didn't feel like spending a ton of money on a new bottom bracket or crank. I'm a big fan of the 1x commuter, and will likely go with a real 11spd system if I ever trade in my Sirrus Sport.

This is a pretty good site for seeing how your gearing will change:

Good chain retention

  • Familiarity: I've used it several times

Easy to install and does a good job with chain retention. If you ride on the rowdier side of things you still might want a guide though.

NW 30T chainring Race face

    I had the chain falling on rocky/bumpy DH.
    New bike, I changed the chain ring, from 32T to 30T on this occasions and with the NW teeth no more chain drop. No need of chain guide.

    Great, chain doesn't pop off

    • Familiarity: I've put it through the wringer

    Chain doesn't pop off at all have the narrow-wide on 2 bikes now, no chain guide, haven't had a pop off yet. The only down side is that I would recommend a bash guard or taco to protect the ring and chain from casing and rocks.


    • Familiarity: I've put it through the wringer

    I decided to drop my front derailleur all together went with this as the replacement. I bought a 36t and a 32t to use interchangeably. Super easy to clean or swap sizes. I have dropped a chain but I'm not currently running a chain guide.

    these teeth bite

    • Familiarity: I've put it through the wringer

    easy to install and have had no issues with loosing my chain running a 1x10 set up. I will never be able to go back to a chain ring that isn't narrow wide.

    these teeth bite

    good bye front derailleur!

    • Familiarity: I've put it through the wringer

    i had had enough with my triple chain ring up front so i took it all off and purchased this guy, no quide needed as long as you have a type 2 rear derailleur. once in a blue moon i will loose a chain. 32t is a decent range for the highs and lows, it does make climbing large hills somewhat painful though.

    Great for an easy conversion.

      Did the poor mans XX by converting shimano XT groupset to a wide range 1x10 with this 42 tooth rear and this narrow wide on the crank. Works great. Have yet to drop a chain despite hundreds of miles of singletrack and bikepacking around Utah this season.

      Simple, Quiet, Functional

      • Familiarity: I've put it through the wringer

      I replaced the 2x on my Santa Cruz Bronson with a 32T narrow-wide, and I'm not looking back. Paired with a clutch-type derailleur, the days of chain-drop are long gone, and I've ditched my bash guard too. The simplicity of the 1x setup is something I still can't get over. My friends are tired of hearing about it.

      This ring installed easily with my stock chain and on the inner ring of my 2x chainring. Even at more extreme chain-lines, the ring is pretty quiet and breaks in to be even quieter.

      There has been slight wear of the anodization where the teeth engage the chain, but it is startlingly minimal after 250 mi of riding.

      Everyone has an opinion about this, but I have yet to encounter something that I could ride up with my 2x that I can't surmount with 1x 32T (11-36 in back). It calls for more power than spinning in a granny gear, but it has only made me faster because I can't go slower a certain RPM and keep the pedals moving. If you live somewhere with really sustained climbs >3 mi at a time, you might like a 30T, or you can convert your cassette to wide-range 11-42 with a wolf tooth or OneUp product.
