    32 tooth chailring

    Hi all. Bit of a strange one..I have a specialized rockhopper x1 with a single chainring (30t) that I'm spinning at high speed. So I'm looking to change it to a 32tooth. However I'm struggling to find one that will fit. Any ideas.

    It's a xp rockhopper pro btw.

    Many thanks.

    What crankset are you running? How is the current chainring attached?
    Once you figure that out call the guys at Worldwidecyclery, for example, and ask them.

    Could be this.

    Hi. It's a stout crankset I think.

    According to this, you may need a 76 BCD ring that is compatible with SRAM XX1:

    Beware, there's a "Rotor REX" 76 BCD ring that's NOT SRAM XX1 compatible:

    Note that I'm just posting this for info on what bolt hole size to look for, not suggesting you drop a tank of gas $ on a chain ring

    If you're spinnng out on a 30, 32 won't help much. You might be better off with a 34 if it'll clear the chainstay. What cassette are you running? Is the small cog 11 or 10t?
    Do the math.

    I always question when someone says they're spinning out in their tallest gear. I won't argue that it can happen, but to spin out a 30/10 or 30/11, you have to be a monster, and you've gotta be absolutely hauling. WELL over 20mph. And not just when you're coasting downhill on the road.

    Depends, I ride mixed surfaces and spin out my 34/11 on occasion which is about the same as 30/10, that's 40+ mph though. On the trail? Never.

    That's what I mean. I am hauling if I am doing 20mph on the trail. That happens occasionally, but almost always when coasting on a fast downhill. A 30/10 gives me plenty on the trail.

    On pavement, I might use my 30/10 for spells, but spinning it out? Not unless I am bombing downhill...and I'm coasting then, anyway. So I still don't need taller.

    If I am legitimately spinning out that kind of gear on a mtb on flat ground (no help from gravity), I should be getting endorsements. And I should probably be on a road bike if the ride involves lengthy stretches of that.

    Of course it depends on lots of factors but personally I'd want a bigger chainring too.

    Bigger than 32? The only other option is going on a double chainring in the front. So new chainring. Lever...

    I thought you said you had a 30t ring? There are other options.

    I used 12th gear the other day with my 30t front. 11t cog.

    Flat tail in an open area, gravel covered. I'm not very strong and was riding plus tires, so I was really only able to use the 30/11 combo for a few seconds at a time. I'm probably the worst person to talk cadence with since I fail at it. I'm too weak to power though to be considered a masher, and my leg geometry just does not let me spin up. Even on a road bike I can't spin quickly.
    Wen riding downhill on my road bike at 45ish, I feel I'm spinning too fast to make any power, without getting too much wobble associated. For those limited instances there is no need for a higher gear range which would ultimately affect every other gear in a negative manner.

    I can't find a reason for ME to want a 30/10 or even 32/11. I actually have considered dropping to a 28t because I have no reason to go that fast usually, and still have a pedal demand.

    Everybody is different though. OP may in fact be cruising right along and need higher gearing.
