just thought i'd share this as i don't think it happens very often. a few days ago i camped in the uwharrie forest and in the morning i left to ride to morrseville, nc. i was about half way, near gold hill, nc, when i stopped at a stop sign and as i stepped down on the crank to get going again, i hear a loud pop. i looked down and thought i threw the chain but it was still on. i got off the bike and looked at the chain and it was fine. i then grabbed the crank realized that it was spinning both ways. the freehub exploded, for lack of a better word. had to hitch a ride to salisbury, nc to a bike shop (windsong bike shop). the mechanic took the hub apart and figured out the spindles inside the up broke. less than 3000 miles on that hub. anyway, the wrench at the shop was able to replace the part of the hub without building a new wheel. he took the part off a new mt bike in the shop and replaced it. got back on the road a couple of hours after making it to the shop.
