Put bottom bracket in (HT2) with mrp chain guide fitted (bb attachment)
Push axle through BB and attach NDS crank...all nice and snug
Tighten up the bit on the NDS to preload the bearings and then tighten the screws on the crank
All nice and tight with no play yet after a ride there is play in the axle - I can slide it side to side by a few mm. Dont think I need any washers but can't explain why something that was tight can loosen off, especially since the nDs crank should be holding the tension on the bearings
Btw, it's Enduro bearings in a HT2 set of cups but that shouldn't cause a problem, should it?
