Found: Wolf Tooth Components Machined Chainrings Fit XX1 to Any Crankset

need this in the uk so bad, I hate running a chain guide

Yet again, these rings are way too big for 1×10 for people who ride up actual mountains. Yes, if you have the XX1 hub/cassette setup with the eleventh 42T platter in the rear, it works. But if your biggest rear cog is 34T or 36T as found on 1x10s and you are not a flatlander, then you need to discard the 104BCD and get a smaller direct-mount ring up front. Please, please, someone make a 25T and 26T for those of us who need to climb!

Tes, these guys do a 28-tooth option which is getting closer:

Hey Tes,
Check out our website photos. Also, the photo above with the Middleburn crank — that’s a 24T! These were specials for a couple of test riders doing some extreme rides but we absolutely do plan to make these smaller sizes. Cannot give you an exact timeframe but we can and will make them.

Tes-You obviously don’t know much about the 1×11 drivetrain and why it even exists…..but then again, you’d need to ride a bit more. I don’t say that as a bash, but that’s the point of XX1 (or 1×10 or 9 even). It’s a purpose built for those who ride….alot….and looking for maximum performance.

XX1 was not designed for people who’d need a sub 30t cog to compliment it. If you can’t ride a 30t-36t front ring, XX1 was not only not designed with you in mind (or any 1x system) but it physically wasn’t designed to go any smaller. While I haven’t tried, I doubt you’d be happy with the results of a 26t-28t front cog as it was not optimized for such.

And btw….I do live in Colorado and I run a 36t front with a standard XX 11-36t cogset. Works just fine for me. And I like my pizza, beer, and Malboro red cigs when I can get them. Seriously….just stick to one of the many 2×10 setups that were designed to work for the masses. Or ride more. It surprising what just a few more hours on the bike a week can do for your ability to push bigger gears.

AWESOME. Any plans for a 120 BCD version like the renthal SR4? I want to be able to switch between 1 and 2x without having to buy a chainguide.

Tes- North Shore Billet makes a 27t direct mount.

This is exactly what SRAM should have done already for those of us who can’t afford or don’t need XX1. It might not work for people like Tes, but for all the people out there running 1×9 or 1×10 drivetrains it is the bee’s knees. (And yes, Tes, these people do ride in the mountains. In fact, a lot of us ride single speeds in the mountains). The main drawback has always been needing a guide on the front but this solves the problem. If I could afford to, I would be buying a clutch rear derailleur and ordering one of these chainrings right now.

“some people do 6 hour days and you just can’t push a 36 the whole time.”

Actually bin judgin, what you mean is “I can’t push a 36 the whole time”. Plenty of people can, you’re just not one of them. Don’t assume everyone’s the same.

Nick, Sevo…you guys are soooo bad-ass!

After the first 3 comments, everything here went to hell.
Yes, HBC really screwed up.
I was wondering the same thing re: SRAM patenting the design…clearly they’ve learned nothing from Specialized.

I’m just going to assume these things will work great with a 9 speed drivetrain…. I don’t see why not at least.

Boover…. did you miss th part about needing a clutched rear der?

Everybody: take a deep breath. (Ahhh…better now.)

As stated at least once, XX1 DOES in fact make even-numbered rings from 28 to 38T. Clearly it is designed to work with all of them, or they wouldn’t exist.

That said, when I built up my Jones (steel diamond) frame with a 4.7 inch fat front / 2.35 inch rear and 1×9 gearing, I used a 27T from (you guessed it) North Shore Billet. (Great service: got it from B.C. in only 7 days. Terrific looking and not a single dropped chain in >200 miles so far. Thanks, guys.) The rear has a Shimano 12-36T 9 speed cassette.

In other words, my climbing gear is a 27/36, which is identical to the climbing gear on my full squish 29er 2×10 (24/38T double + 12-36T 10 speed cassette).

What did I lose? Well, three ratios at the top end only: 38/12, 38/14, and 38/16 (and the 38/16 is a BARELY bigger gear than is my 27/12). I only miss those three ratios on the road or on long, smooth downhill sections.

Honestly, if you want to try the whole XX1 concept on the cheap, take your X9 or X0 spider off and call NSB (North Shore Billet) for a spider / chainring combo. For $60 bucks, you can see if it’s for you or not.

Cheers,
E

@Tes: WTF are you talking about. I ride up actual mountains on a frigging single speed. On my 1×10 with 36t rear I can climb for hours – and I am not a strong climber. It is pretty low enough.

I am not Old Neverend, but I can ride anything in the rockies with a 34/34. If you cannot- ride a triple.

32 tooth front only and 11-36 rear in Colorado. Man up and train on your SS. Break out the 1×10 for days you don’t feel like walking in the mountains.

Robin, you don’t need Sheldon. Run a SRAM 9sp 1:1 shifter with a shimano shadow + mech. They are fully compatible. Bam, 9sp clutched. The wolf on 9sp… Don’t know about, sorry. I hope and assume same.
