Does any one know what bottom bracket length I need for an M900 chain set in an S works frame shell size 73mm ?

107 or 113, take your pick

If you are on the 34.9 band size front mech then the stroke is probably best on a 113 bottom bracket, if not then a 107 bottom bracket is best.

The stroke range on a 34.9mm is 3mm further out from the centre than a 28.6 one (same as the drive positioning side difference from a 107 to 113 bottom bracket)
