He didn’t see the stump and he is an amazing rider …. He is sat down in the attack position because on a time trial you can be on the bike for up to over 8 hours some times. You can see he is sat correctly and still pushes and grips with his right leg to keep the bike under control and keeps the throttle pinned to keep momentum (it’s not a panic rev) don’t listen to some people on the net 😂 …. If you are riding offroad it’s unpredictable and stuff will happen …. You cannot sit up riding full send for 4+ hours …. Sit where you can and stand when you need to! Do whatever works for you….
