I have a brand new Titanium Boost 29er hardtail. The frame uses a PF30 BB and the BB shell is 73mm wide.
I have installed the recommended RaceFace cinch PF30 bottom bracket with a Race face Next SL crank - 175mm arms and 32t single chain-ring.
The problem is that the clearance between the chain stay and the crank arm is next to nothing. There is no contact yet but I am unable to run the recommended crank boot protector.
The instruction for this BB so not to use any spacers since it 73mm (68mm ones use spacers).
Adding spacers wont help as it does not lengthen the spindle. I do not see how a Shimano XTR/XT crank will work here either since it has the same Q-factor.
Any other ideas?
