|I heard that at the Chicago round of the Supercup series last year, Gullickson and Johnson were jumping off their bikes at 30mph for the series of barriers called the six-pack. Anyone know if this is accurate info.? How can anybody make their legs move that fast. I have a hard time reaching that speed on my road bike never mind trying to jump off it at that speed. Wow.|

|up in the Santa Monica mountains and I have to ride back down Sunset Blvd. w/ my right bloody butt cheek hanging out from my torn lycra shorts. And I am still paying for that crash. Oh well.....

|considering a human being's maximum speed running is about 22 mph, I don't think anyone is (successfully) doing 30 mph dismounts. As an ex downhill and DS skateboarder I have had numerous experience with 30 mph(+) dismounts. If your legs can stand the abuse of the decelleration and you can keep them up with the upper half of your body (which is still travelling 30) you may be able to avoid slamming face first into the ground. Add to that you are picking up a 19 lb object (with weird balance)and carefully running hurdles, the armchair physicist in me cries BS. They could be coming in at 30 slamming their brakes to rapidly slow down before they jump, but jumping at 30....nope don't think so.|

|30 km/h maybe, 30 mph hmmmmm......|

|good point 30 km/h is roughly 18.6 mph which is far more believable|

|atpjunkie is exactly right. They were probably doing close to 30 mph coming into the barriers (Called the six-pack, but there were only 5. Figure that one out.), but with some quick braking before the dismount, they were running at a managable speed. Still faster than I could do gracefully though.|

|good. glad to straighten that out. If you think about it 30 mph is TdF TT speed. Could you imagine Lance or whoever dismounting at that speed? was there a downhill coming into it? I just don't see cxers hitting 30 on a dirt flat.|

|Thanks for clearing that up people.|

|I have done that no problem.
Took about 10 days to get back on the bike though...
