The Delgado Cross's are cheap, and BOMBPROOF. My friend/coworker built some up 36h 3x with Revolution spokes and was dropping off a 4.5' conrete stage to flat concrete and never had to true them. We have since built probably 6 sets of wheels with these rims and they always build up nicely and withstand nearly anything. We actually use these now instead of Velocities because the Delgado's build up much more consitently and seem to be of a much more consistent quality.
