Great App

This app was instrumental in convincing me (and my bike shop mechanic) that I should convert my new 2x10 to a 3x10 for the type of terrain in my area. Quick, easy, wealth of information, and with great explanations for terms and concepts to boot! This is a must have for anyone interested in comparative gearing.
