Q & A


The Shimano UN54 utilises a square taper spindle, making it an ideal upgrade or replacement bottom bracket for traditional chainsets. Available in a number of shell widths, threads and spindle lengths. The cartridge design allows easy installation without the need for adjustment.

Super accurate, high tolerance bearings and a hollow spindle allow for smooth operation and reduced rotating mass, resulting in less resistance. The sealed cartridge assembly with oversized ball bearings and maintenance free high efficiency rubber seals keep out dirt, mud and water, increasing performance and lengthening service intervals.
