i had the XT 770 groupset on my sherpa any amount of gears but there was no adjustment on the rear mech ,i put inling adjuster on the cable but it was next to useless, a bike rides different once u load it up so the gears need adjusting to get the change spot on .
anyhow the compact is not set in stone i still might go for a triple 48 34 28 and 11 to 32 on the rear or maybe buy a long cage rear mech and get the 34 cassette .
wonder has FSA got a triple in those combo's any suggestions on a nice triple crankset kinda set on tiagra sti front and rear mechs.
