No jumping chains.
The e*Thirteen Guidering is perfect for any single chainring application -- singlespeed or 1 x configurations, with or without a chainguide. It's CNC machined from long wearing 7075-T6 aluminum. It's made to fit any four arm crank with a 104mm bolt circle. It's also compatible with 8-, 9-, and 10-speed chains. Guiderings are available in even and odd tooth counts from 32t to 40t, they come in anodized Black.
- Ultra-tough aluminum construction lasts for seasons of abuse
- A 104-millimeter bolt circle diameter offers compatibility with nearly all mountain cranks and chainguides
- Variety of anodized colors lend some bling to your rig

Flashy, functional, overall very good

- Familiarity: I've put it through the wringer
I've ridden two of these now on my 1x9 setup. The first wore out after about a year (~2000 miles; I ride and race a lot of dirt). It was still functional, it just had one tooth worn really far down. So durability is very good, but not fantastically unbelievable (unlike, say, the Blackspire Mono Veloce ring I've had on another bike for forever that the ano still hasn't even worn off).
Performance-wise it's a chainring, I mean what can I say? It's got a tall tooth profile for single ring use. I use it for 1x9 as I said and it works great for that. It still needs a chain retention device (I use a MRP 1.x), but it doesn't try to buck the chain under load at all, the chain retention device is mainly to keep the chain down while I'm bombing down really rough stuff as it's a hardtail and gets some bucking.
The reason I buy this and not just another Blackspire (which is functionally identical and has better durability) is the colors and tooth selection. Well, maybe not tooth selection personally (I use a 34T, but the Blackspire only comes in 32, 34, and 36 so you're out of luck for 33 or 35T), but the color aspect cannot be understated. I have a lot of red ano highlights on my race bike and the red ano chainring just looks so damn good, it's worth it to me to replace it once a year. Ok, so it's shallow, but if you look fabulous you ride faster. It's a fact.
Will these work on my Shimano XT Deore...
Will these work on my Shimano XT Deore crankset? its the 3x10 system - thanks in advance
Only if you are converting to a single up front and removing the large and small rings. This ring may work for a 3 ring set-up but it wouldn't be ideal.
Just got it and installed it. It looks good, it feels pretty solid, the weight is great, did I mention it looks good? I'll update many miles later to see if durability matches up.
