Hello. I am new to the sport and was hoping someone can give me an idea on whar gears I should run for the following scenarios for a 650 bike.

Flats

Hills

We have both here on Guam. Most training rides are on hills and actual Tris are flat. I know what should run for 700c wheels but not 650c wheels. Can someone give me a good idea. I have a cervelo P2k so keep in mind the chainstays are shorter so some gears may not work too well. Thanks.

Jason
