That's good to know. Are there specific tools involved or do they use a brute force method?
You need a frame alignment tool to make sure that you spread the frame evenly.
After spreading the frame, you use a dropout alignment tool to make sure the dropouts are parallel.
As far as wheels go, I have 36h Velocity deep V rims, DT 14g spokes(of course), and campy veloce hubs. Bombproof. I ride trails on my road bike all the time, hop curbs, etc. I'm pushing 2 bills. The mavic cxp22 is very durable as well.
