I really just thought about this until this past week while on the trainer and I want to figure this out to have a more comfortable ride.
On tour rides i am sitting for hours and my butt gets sore sometimes. During the rides now I will use my legs, arms, drops and weight shifts to relieve the pressure on the rear. This will strengthen my legs. The stronger legs will help power the ride. Too many times I have felt that I was spinning and rooted on the seat. I felt that pushing the pedals down with the leg muscles will add power; at least more than just the spinning the mass of my legs.
Do road riders hover over the seat, straddling the seat most of the time. Doesn't seat allow you better balance?
What do you think? I will give you my conclusion after some long spring rides.
I love my riding days and look to find interesting and informative items to share.
