Finally got around to installing my XX1 crank, or attempt to do so atleast when I ran into a problem on my '12 Scalpel.
From reading the manual for the frame, the manual for the xx1 crank and measuring the bb myself it is a 73mm bb.
However, when I put the crankset on with no shims as the xx1 manual stated, the chainring grinds against the chainstay. I used the flat faced BB shields.
Should I put a shim on even though the manual says it isn't required?
For a 68mm bb the manual states that 1 shim should be used on each side.
Thank you for any help!
