Hi,
If I clamp the bike by the seat post , the weight of the front wheel, causes the bike to rotate, regardless of how much I tighten the clutch control. That means there is only one position that I can work on the bike. With the front wheel almost touching the ground and the rest at an odd angle up in the air. If I try to rotate the front wheel up, the clutch cannot hold it and gravity brings the front wheel down again.
Any suggestions? It is a well built piece of kit, but is anyone else having this problem.
