    DUB inner race seal sourcing

    I messed up the o ring that goes between the inner race and the spindle. Went to the bike shop and they called SRAM. Apparently itís not a part SRAM sells. They said they do have some out of spec or damaged BBs that they will salvage those seals out of for me and send them our way. But I wondering if anyone had any luck with sourcing from other places on that?

    Went through the same process with talking to a few bike shops and Sram. No one could tell me the size of the oring.

    I ended up measuring the good oring. The oring size is 1mm cross section X 29mm ID. The blue DUB oring appears to be silicone. The orings I ordered from The Oring Store are Buna, 70 durometer. Perfect fit.

    Tried a few hardware stores as well. They don't carry orings with a 1mm (0.039") c/s. Smallest you may find is 1/16". Mcmaster carries 1mm c/s orings but no 29mm ID.

    This is the oring I ordered. It's a metric size.
