@Chakers1998 i'm using a pro4 ss in the rear so changing the chain-line isn't a problem. With the saint i need to have the crank about 4mm farther out on the drive side and the axle is only so long. If i assemble it with extra spacers in in the bb i cant get the plastic Crank Arm Fixing Bolt to engage. I could machine down the granny ring mounts but that seams a bit 1 way if it doen't work
