    Cog bent/broken off on X01 cassette, pics inside

    I was getting some badddd skipping in the 9th/10th cogs. I took a closer look and had a bent tooth. I asked a friend if they thought SRAM would warranty it and they said no so I tried to bend it back, as I've done previously with a Shimano cassette (and continued to ride for many miles after), and it broke right off.

    It seems to shift fine in the stand, but should this be replaced? In other words, is it dangerous to ride it like this?

    Second opinions on whether SRAM will warranty this? The cassette has 317 miles on it, as does the chain. It was adjusted perfectly with no issues prior to this.

    They would probably be more likely to warranty it if you hadn't broken it off attempting to straighten it, but it doesn't hurt to ask.

    I moved it 1mm and it snapped clean off... no wiggling back and forth to get it perfect, it just snapped off the second there was movement.

    Hardened metal doesn't like being bent, on top of that being one of the thinner, shaped teeth for chain pickup. I find it extremely unlikely that they would warranty a broken pickup tooth--just because they say that the cassette cluster can shift under load, doesn't mean that you should.

    That said, one broken tooth on a 14 (15?) tooth sprocket won't kill you.

    You might get some Skipping hence grinding other cogs. It depends how much of a torque rider you are. If it were me, I'd replace the cassette (or the chain ring if possible) as I've had this happen to me before. I'm a grinder though ^. ^

    I broke a tooth off an XX1 cassette recently. It had ~5000 miles on it, though, and the entire thing is pretty worn. Luckily I had two spares, and new chains to go with them.

    This just happened to my XG1180 too. I dont actually know when it happened, I just noticed it while changing tire. I didnt notice any trouble while riding. Im not sure how many km Ive ridden it. Im only like 50km or so into my second chain though. Considering the price of the cassette it should of lasted longer. But what can you do, Ill have to just order a new one.

    Me personally, I would just continue to ride with it.
