    Podium Chainstay chainslap --advice needed

    I am getting some chainslap at the pivot near the hub on the right side chainstay (Whistler is brutal on bikes). Obviously, this is occurring when geared down in the smallest cog.

    I use a 11T as my smallest cog, and I think it is a 28 largest (iirc its a shimano 105 10spd)

    I've thought about going to a 12T, but don't think that would fix it. I could cover it with something, but before that I was wondering if maybe there was something else I could do, or something I am doing wrong that I can adjust and make this not happen.

    Sorry for the bad pic.

    Happening here as well. There are a couple things to do...First, beef up the tape job preceding the slap area so that the chain hits higher initially and thus can't reach the slap area. Second, apply that rubber mastic tape to the slap area to deaden the noise and offer some protection.

    No problems here - running a 12T high gear on the rear cassette with a 36T up front and 2012 Saint. (the one without the clutch) I have a lizard skins chainstay protector on there and it seems to be doing the job just fine - I've ridden some very rough terrain and no having any issues with the chain hitting the pivot area at all.

    could easily be wrong, but when i read this i automatically thought, chain not right length and could do with a clutched mech. ive got 11T and 38T upfront with X9 clutched mech. chain has never touched the frame once. be lucky if it swings up and down more than 0.75 inch after impacts. HTH.

    Mine is showing the same wear, but not sure it's quite as bad as RDH's. Chain's the correct length.
