    What chainring to replace current one with?

    This is what I have... a 2x10 with 22A/33A and bash guard, 4-bolt, 104/64mm
    The big ring, the 33,t has broken about 4 teeth on it and even with filling them down and trying to bend some back I think it is time to replace it. This is on a Stumpy FSR. I like the 33t ring I think it fits my riding well any suggestions on a replacement?

    Oh and if it make any difference this is a custom SRAM S-1250, 10-speed XC Trail double, GXP spindle, XC guard, 175mm arms, in other words the stock 2011 setup...

    Would like to upgrade to something stronger and lighter if possible.

    Stronger and lighter = more expensive. Personally, for 33t in that pattern, I would choose a Homebrew ring. If you want a 34t, I would go with Blackspire.

    thanks greenlightgo I figure on it costing more no doubt. I guess I need to consider going to a 32t or 34t for more options huh?

    e13 also do 33T. Incredibly light and mine has lasted well. For the ultimate though, HbC is pretty much the way to go.

    Are the HBC rings ramped? Couldn't find any info on their site. This is a 2x10 setup.

    They do not have to be ramped for shifting. Sure, makes it slightly nicer, but I have had no issue using non-ramped rings. Dan might want to jump in here (or you email him) regarding the increased tooth height of his rings, as that might cause an issue.

    I'd agree with GLG on the Blackspire and be more specific and say get the Super Pro version. Have to ask, if your current crank has a bash, how'd you trash the chainring so badly?

    I emailed dan to get his thoughts. I am a little leery not having it ramped. Are the blacksphire ramped?

    Not sure how I have done so much damage. Did have the front derailure out of alignment today and just ran with it. That might have caused one of the teeth to break but the other three???

    Rotor Q makes a 33t ring. They are expensive but supposedly have some pedaling advantages.

    $93 on the Rotor Online website for the 33T 104mm BCD.

    Couldn't find it got a link? Google didn't bring it up.

    Also I'm thinking of going with a 32t or 34t. How big a difference are we talking going either way from a 33t?

    Well, the Rotor 33T ring is like a 32T at its "narrow" point and like a 34T at its "widest" point on the oval.

    If you want to know differences, just plug your rings and cassette (wheel size, crank length, etc... as well) into the late Uncle Sheldon's gear calculator so you know exactly how things would feel.
