Wow, you may have just become my new hero. There's some serious hills on the way to and from work and I've been killing myself trying to get up and down them, I'm going to try this Tuesday when I head to work (Or tomorrow if I end up biking to my sisters house)

I am unsure how it helps, in my case it probably makes me a little more aerodynamic since I've such a very upright riding position, but regardless, it helps
