BBLock BB386/PF30 BlackBearing Bottom Bracket - 29mm (DUB)

BLACKBEARING BOTTOM BRACKET BB386/PF30 - DUB

The BlackBearing BBLock bottom bracket is designed for frames using the BB386/PF30 standard with a 46 mm internal diameter. Compatible with SRAM/Truvativ/5DEV cranksets featuring a DUB (28.99 mm) axle, it is equipped with BlackBearing B5 bearings offering an excellent balance of smoothness, durability, and reliability. Suitable for MTB, road, gravel, cyclocross, or BMX use, this bottom bracket ensures precise installation and high-performance operation for demanding riders.

The “BBLOCK” technology is a two-piece threaded bottom bracket that improves smoothness, performance, and reduces creaking thanks to better alignment. It also enables cost-effective maintenance, as only the bearings need to be replaced without removing the bottom bracket or damaging the frame. This design extends product lifespan and reduces environmental impact.

Note: The bottom bracket is supplied with spacers that can be installed if necessary. A tool adapter is also included.
