+1 10 min tops for a ratio change....
I am also considering going to the XTR rapid rise RD makes shifting while climbing under load much cleaner (or so says Lord Sheldon) ... also opens up the possibility of a true Bailout Gear... I'm training for the San Francisco -> Los Angeles Aids Ride and there are some spots where a 34t might not be such a bad idea !!!!! Better to have it and not use it than need it and not have it... especially if you can change it out in 10 min
