| Quote from the rider behind at the time (as posted in the thread)
“I was directly behind him. His wheel exploded at 120 MPH between turn 7 and 8 at Thundehill raceway. The bike had never been dropped, dumped or crashed before. BTW, the hoop is torn in half for anyone who hasn't seen it up close in-person.” 900CR
BST's comments are more than iffy IMHO and understandably designed to fend off product litigation. When a wheel breaks up at high speed it is unlikely that the bike will come down with a bump directly upright, it's going to go all over the place.
A couple of years ago I met a senior director of Dymag at a dinner party and talked to him about the company's CF swing arm recall. He was shocked I even knew about it and claimed it was the result of overtightening of nuts and nothing to do with the CF, he then admitted that CF has 'certain properties' which make it very strong, but 'not very resistant to impact'
If the nuts are overtightened on a mag arm or wheel then they strip, and if you hit a pothole with a mag or ally wheel it bends and doesn't fall apart.
Even the main factories don't use CF in wheels at GP and WSB levels.  |
