Moquai Bottom Bracket - Ceramic | BSA-68/73-24

The CNC-milled bearing cups from Moquai are bolted into the bottom bracket shell. This installation method prevents annoying cracking noises and makes it easier to remove them later. Designed for maximum longevity, the hybrid bearings are optimally protected against contamination in order to withstand even the most difficult operating conditions. The use of ceramic balls promises a four times longer service life.

The bottom bracket is suitable for frames with a BSA thread (1.37" x 24 tpi) and a shell width of 68 or 73 mm. Designed for cranksets with a Shimano Hollowtech II crankshaft (24 mm diameter).

Important note: A special Moquai bottom bracket tool is required for installation (available separately). For mounting the BSA bearing cups, the MQ-BBT-Z27 tool ("5-in-1") is suitable.
