Stripped disc hub
So I guess the bicep curls have been working...I stripped one of the screw holes on my rear Mavic Crossmax XL. I now have only 5 holes. Has anybody had this happen and what did you do? Can I ride it like that? I am thinking of just going to the hardware store and getting a nut to put behind the hole. First post...thanks in advance.

I think that the best way to correct this is to use a helicoil or other helical threaded insert. What you do is drill out the hole to a larger size, tap that hole, then install the insert. I'm not sure what size the disk brake mounting holes are, but I bet that it's possible to find either the correct insert, or to find an inch insert that is close and size, then use one different torx screw. If you do go this route, I highly recomend the "tangless" inserts, they are much, much easier to deal with when working with this size.

If he drills the hole larger, he might run out of material around the hole...
People on the MTBR weight weenie forum have talked about only using 3 bolts out of the 6...but yeah, a longer bolt with a nut on the end would work. Time to buy a torque wrench!

If the bolthole goes all the way through that part of the hub, and there is room back there for a nut, then I think that using a nut behind it would be a good solution. I presume it would take a somewhat longer bolt to grab the nut. I am trying to picture the disk hubs I have seen, but I would have thought those were blind holes that were not open on the backside. But, if it is, then go for it.
