It was the ramparts that did us in, with that big shot to one wheel at the start of each crossing. We told our driver to drive it as if he stole it, and he did not disappoint. 
A spacer within the tube may have bought us time, but failure was inevitable. the other side of the tubing has significant stress cracks. As it was, the thing made it halfway through its 17th match before it failed. The new frame ( 0.125" wall thickness) seems bulletproof so far. We would have started off with that if we'd fully understood the brutality of this game. |
You said this drivetrain was in a WCD configuration, but you seem to have described a timebomb.
