Runs fine on all gears just jumps/slips a little on the granny ring and number 2, 1,3-9 are fine(strange)
I put new bearings in the lower chain guide and cannot remember if the angled bit of the roller faces away or to the bike,very much doubt if that’s got anything todo with the chain snapping tho.
The power link is just weird because 1 end was still connected and the other end opened up.
