How difficult is it ot upgrade from 9 to 10? Can it be done easily?
For a wide range cassette use the Santana and not the IRD. The Santana cassette works but the IRD seems to be a problem. It is surprising how the 10th cog takes the jumps out on the Santana 11-34 but the 10 speed is more finicky. The 10 speed chains are reported to wear out faster, up to 50% faster and the Santana cog sets are $170.
