Sorry - can't help with the OP, but in the interests of sharing.... My disaster was a bit of a mixed blessing as it killed my nasty Dawes Edge Pro HT, and forced me to buy a proper bike.
After mincing the DH bit at Hamsterley in seriously sodden conditions a couple of times, and witnessing both my mates have potentially lethal offs, I decided to go and have a pedal round the red route whilst they continued trying to kill themselves.
When I'd finished, I went and waited at the carpark for them in the p1ssing rain for half an hour. When they finally showed up, bleeding and broken, I chucked their bikes onto the rack with mine on top. Managed to secure both their bikes properly but my fingers were too numb to properly attatch mine.....
Needless to say, the lack of effort on my part came home to roost about ten minutes later - the car behind us flashing furiously and beeping. Stopped, got out and saw my bike was trailing behind us on the road - utterly mashed up with its front wheel caught in my mate's pedal.
Devestated at the time, but was consoled by the reassuring noises made by the insurance company
