I have been wrenching my own bikes for over 40 years, but this is the first bike I've owned with shimano sti shifters. I am trying to fine tune them with little success. I did a google search, but did not come up with much. Anyone got step by step instructions, or know where I can find something like that. And on a semi related topic. Also new to a 10 speed cassette, heard a new terml, cross chaining. compact double up front, so how many cogs on the lower end of the cassette are cross chaining with the small ring up front and vice versa?
