Being older and bigger guy I need to have a granny gear for climbing the 7-9% grades in western New Mexico. After talking with a mechanic from the Trek SuperStore in Albuquerque he said that this would allow me to run a 11-36t 10-speed cassette on my Bianchi road bike using Shimano 105 shifters. Even though it is labeled as 9-speed it works well with the 10-speed set up. The only major issue was dialing in the B screw on the back to get a gap so that gears don't touch the freewheels of the derailleur.
