I have a single ring raceface ride crank on a 2015 whyte g 150 frame, (68mm bottom bracket shell), I have one spacer on the non drive side and two spacers on the drive side as per instructions, BB is a raceface x-type.
For some reason when I tighten the drive side crank bolt it seems to load the bearings causing resistance to the crank spinning freely, if i leave the bolt loose enough for the crank to spin freely then the crank arm works loose during a ride. The crank bolt is the single 8mm bolt type, not the self extracting one. Any thoughts would be apppreciated.
Sorry please ignore, as I was writing this I realised I had not measured the BB shell, it is in fact 73mm, so a quick swap around of spacers and problem solved, lesson learnt dont assume measure.
