The BlackBearing 46-68/92 Dub B5 Bottom Bracket is designed for cyclists using compatible SRAM Dub cranksets. It provides a replacement for worn bottom brackets while improving bearing alignment through its connected aluminium cup construction. Suitable for road and mountain bikes, it offers a serviceable alternative to conventional independent press-fit cups.

Stable Bearing Alignment. The machined aluminium cups screw together inside the frame, helping maintain alignment and reduce movement that can cause bottom bracket creaking. The B5 steel bearings support smooth crank rotation during regular riding.

Easier Maintenance. The replaceable bearing design allows worn bearings to be changed without removing the complete bottom bracket housing, reducing repeated stress on the frame. Before installation, confirm compatibility with the frame shell and crankset to ensure proper fitment.
