I learned from a Ryan Hughes and Andrew Short DVD's that when your in a rut that will hold the bike in place, the two of them both said, you want to sit straight with the bike (inside leg lifted high along the side of the front fork) weight centered (front to back) this helps keep both tires anchored in the corner. I understood you only weight the outside peg on a 'bermless' <flat corner>.
They said it was important to to take note of the angle of the rut <faster riders will create a steeper angled rut> <slower riders will create a less angled rut> this helps keep your balance as you sling shot through the corner.
I had no idea I really Suck at ruts until this year. I'm trying to learn everything I can!! TELL ME if I'm wrong about the above information!? Thanks
