asked by: a guest Will these work on the Shimano UN 54 bottom Bracket?
A.
anwered by: bhardy These will not work on the UN 54 since XTR cranks use a completely different bottom bracket system. If you need crank bolts for a UN 54, try the Sugino 8mm Hex Crank Arm Fixing Bolt. You can find it by pasting "333222342814" into our search bar.
