It's hip to be square.
With the Shimano UN55 Square Taper Bottom Bracket, you get a highly durable, smooth-rolling bottom bracket for threaded bottom bracket shells and square-tapered cranksets. The sealed bearing cartridges keep water, dirt, mud, and road grime from penetrating the unit, keeping your bottom bracket rolling grind-free for seasons.
