I am fitting some SLX cranks on a mondraker summum (73mm bb). The cranks are the double bash setup, I am using the 36 tooth ring as the single ring. Frame is iscg 05. The chain tabs for the small ring on the cranks do not clear my chain guide bolts(gamut P30) so I started to file them down. But now realised there is not enough space between the chain ring and the gamut rollers for a chain. I have one 2.5mm spacer drive side. Can anyone see what is wrong?
