I recently installed an XX1 crank after moving my existing cranks to my son's bike. I am interested in purchasing an MRP XCG (bb version) to offer some protection for the chainring. I measured the bb and it is 73mm and does not appear to have an shims installed. Normally, I would removed the shim and let the bash guard space out the bb, but without it, it will space out the crank on the drive side.

Should I be concerned with this added offset to the drive side.
