I'm riding on my Burton Process ICS with Custom EST bindings.
They have an adjustable angle highback.
For majority groomer riding, what would having my highbacks pumped all the way forward do?
I assume it would force my knees to bend so that would be a good thing right?
If you have problems bending your knees enough... setting the forward lean to the max setting can help teach you to ride in a more athletic posture...
However, for regular riding... just angle them enough so they just barely touch the back of you boots when you are strapped in (you can strap in your boots by themselves in the house to get the angles right).
