My Salsa Casseroll has a triple crankset on the bike. I am upgrading it to 10 speed. If I replace the triple with a "adventure" double, like the Velo Orange 46/30 crankset with a stated chainline of 43.5mm and a 144mm Q Factor. Will i need to shim the 46/30 crank to get a good chainline or is 43.5mm good to go? (FYI: I am changing everything to 10sp - f/r derailleurs, chain, crank, shifters).

Also, the VO website recommends a 118mm Spindle length BB for the 46/30 crankset (JIS square taper). Is that going to work correctly on my Casseroll?
