That has gotta hurt! i didn't have any crashes it was all just on some logs in the woods near me. They have claimed in the last 2 weeks a disc my front and back hub, some handlebars and 2 chains! With the chains i wasn't even pedaling i was just doing some pivots when the first went then with the second i was doing a wheelie on the way home with my mate seeing who could go the longest when the chain snapped i went over the handlebars and smacked my knee onto the curb which hurt but luckily i just got a lovely blue and black leg.
