Running a 12/25 soon a 12/27 with a 53/39. I have a 30 for a bail out. I am trying to not use it.

The cranks turn easy. No way am I Lance Armstronging at 90 rpm more likely 60 - 70 rpm.

I turn comfortably for the hour or so commute. I generally sit for the entire commute I only come out of the saddle for a really hard hill. I'd say that one is 8% or 9% over 500 or 1000 feet. On that one I have to come out of the saddle. I can sit for whole hill, but it is a struggle.

Again thanks. I learned a lot. I think I will put a 25 on the back and a 23 on the front. I think that will give me the contact patch I need on the back and the aero on the front to help with the aero.

I am going to work on lower strength and conditioning. Thanks.
