    No good 33 tooth Outcast chain ring/crank failure

    I use my V brake outcast to commute and it is my only mtb, when I take it to the trails I ride it hard but this happened when I was leaving campus after being stopped at a stop sign. I heard a aloud pop and then the clink of the chain ring bolts hitting the pavement. and then a scratch as the bent chain ring dug into my frame. Has anyone else had this problem? Why would this happen, cheap chain ring or crank? One of the four mounting points for the bolts on the crank is bent so my outcast will need at least a new drive side arm but after this experience I think its time to upgrade the part... not something I really wanted to do on this $350 bike.

    Loose chain ring bolts. Did you use blue Locktite?

    FWIW, I alway's Locktite them, the blue stuff (242). The bent ear may be able to be straightened, use a large adjustable wrench and go slow.

    thanks for the tip, I think I'll give that a try. What bolts do you use? I had origin 8 bolts on it

    Use any steel chain ring bolts, I have broken alloy bolts.
