RaceFace 104mm Single Chain Ring

Single chain...I sent it back

If youre looking at this chainring, you probably already know why youre looking for one. Buy it. I run this on both of my mountain bikes, 34t on a nukeproof mega 1x11 27.5 and 30t of my 1x10 sc highball 29. Throw on a bash/guide and youll have a bulletproof all-mountain drivetrain.

Looks great and fits perfectly

I had this ring on my bike in a fixed gear application for about 8 months or so before it exploded on me. In retrospect, using it in this capacity was probably not too bright; it is really lightweight and seems to be intended for a 1x setup in which there would be less torque applied. When it failed on me, I was applying back pressure on my pedals to slow my descent down a steep hill. The drivetrain creaked and squeaked, and then the chain ring literally blew into pieces. Im giving it three stars because it seemed really well engineered and performed well under intense pressure right up until it failed catastrophically. I imagine that most people would want this for a 1x drivetrain, and I think it would be perfect in that application. However, Race Face should make it more explicitly clear that it isnt suitable for fixed gear-level torque. I now use a heavier stainless steel chain ring and feel much more confident about it.

Race face makes good rings, but single rings systems dont last as long as the old 2x and 3x, one ring is doing all the work, all the time. After about a year the wide part wears out and you drop you chain nearly every ride, time to buy another $50 ring. Nice little system to sell mountain bikers a new ring every year. On the good side, its trendy, and allows you to get rid of the front derailleur/shifter. Steel teeth would be better.

Ive used a few of these over the years and I have no intention of switching to another brand. This narrow wide lasts a long time and really does the job of keeping the chain on the ring.

Works great with XT 1x11. Also works great on my buddies SRAM 1x10.

Converted MTB to 1x. Exactly what I needed. Works like a charm..

Excellent product!

Raceface obviously did their homework when designing this ring. Worked best for me with an 11spd chain.
