Moquai Bottom Bracket - SUJ2 | BSA-68/73-DUB

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. The durable ball bearings made of high-carbon SUJ2 steel are characterized by their increased wear resistance, toughness and hardness. 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 SRAM DUB crankshaft (28.99 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.
