are those calf implants? nice…

saw a video of a guy doing an attempt at the downhill mtbike speed record with a very similar get up. Made it on a beefed up version then tried again on his superlight carbon rig. Didn’t go so well the second time around. Figure he might be out of the hospital about now too.

saw a video of a girl from utah do that. she wiped out at 140 mph. carbon bike pretty much disintegrated.
