Moquai Bottom Bracket - SUJ2 | BB386 | PF46-86.5-29

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 shell width of 86.5 mm and a diameter of 46 mm (BB386). Designed for cranksets with a DUB crankshaft (29 mm diameter). Important note: A special Moquai bottom bracket tool is required for installation (available separately). For mounting the BB386 bearing cups, the MQ-BBT-41ST tool is suitable.
