    Truvativ Hussfet Isis Worn Out


    I have some play between my crankset and my bottom bracket (ISIS Hussefelt). It is obviously the crank arms that are worn out, but I was wondering: should I change the cranks only or the BB too?

    The aluminum of the cranks worns easy when they were untight, but does the cromo axle do too? I mean this is something I cant see by eye only, I guess, and there are so much forces at this very spot that it could have consequences on the new cranks even if the axle is slightly worn. Am I right?

    Yes, I think so.

    Also check the BB bearings for wear as well.

    All tapered spindles will eventually wear out.

    Since you're already replacing the cranks, might as well replace the BB too. Have you thought about outboard bearings at all? Something with a pinchbolt design like the Shimanos? This eliminates the pitfalls of ISIS.

    Thanks guys,that's what I thought, but isn't the BB for this crank already an outboard one? It is a Howitzer XR.

    Now that I am going to change, I'm thinking about getting a FSA GAP or gravity. Those look good, simple and with less parts that can move. Anybody ever tried one of these?
