Shimano 105 5500 Bottom Bracket

The Shimano sealed bottom bracket is one of the most reliable components in bicycling. Once you get to 105 standard with its oversized hollow axle with splined ends for a more rigid, non-loosening crank interface, it becomes awesome. 250-259g. We do the 105 5500 bottom bracket in 3 fits: 68/109.5mm British thread for double chainsets 68/118.5mm British thread for triple chainsets 70/109.5mm Italian thread (for Colnagos etc) for double chainsets
