Product Details

Problem Solvers Replacement Aluminum Left Cup f/68mm UN54 Bottom Bracket

If you broke the plastic left cup on your BB UN54, replace it with this high quality aluminum one!
Shimano compatible. For 68mm BB sets.

There's nothing wrong with the plastic left cups on the newer UN54 series BBs.
But sometimes they get tightened down too much and crack.
