For example, 2 hands + 2 feet + butt on seat = 5 points of contact. You really need 4 points at all times to be in control. He was probably switching hand positions, hits the bump, butt comes off the seat while only one hand on bar, now he has only 3 points of contact, tough to recover from on its own, then he grazes against the white line edge.

Perhaps seeing this, Jens appeared to be changing his grip. His front tire made contact with the white line of paint once crossing this point, you can see the paint take the wheel and allow it to slide. Bad timing and position unfortunately as I think his weight wasnt distributed on the bars evenly.

Focus on the front wheel and notice how it slips exactly as he crosses the line and then continues to slide down the painted line following the lowest co-efficient of friction. His hand movement at precisely the wrong time may have may have exasperated the front tires tendency to slip. Once your front wheel looses rotation your down. That's why the guy falls/looses control who hits your wheel wheel from behind.keagandoghttps://www.blogger.com/profile/05586140555124566814noreply@blogger.comtag:blogger.com,1999:blog-4786784182488135171.post-35765008904595037472009-07-22T18:36:40.295+04:002009-07-22T18:36:40.295+04:00It looks like his left hand misses the drop as he&...It looks like his left hand misses the drop as he's changing positions.
