Finally getting around to building up the 88 trek 850 into a touring setup. Installing a new Shimano FC-M591 Deore Crank+BB and the spacer instructions don't work. Shimano instructions show (for 68mm shell) three spacers on right (2.5 + 0.7 + 1.8) and one on the left (2.5). All are required to fit the crank to the BB shell, but Shimano's recommendations throw my chainrings way outside where it should be. Even the arm distances from the chainstays are off (much closer on non-DS than DS). I'll rearrange the spacers until it works right, but I'm curious if others have seen this. Or maybe I shouldn't have read the directions at all.
