SRAM DUB Road Wide Bottom Bracket | PressFit BB86

With this SRAM DUB Road Wide bottom bracket, you enable the use of wider cranksets on your BB86 gravel bike frame. The inclusion of spacers creates additional space for the crank axle, thereby extending the chainline. This adjustment allows for the external placement of electronically controlled AXS front derailleurs in 2x12-speed setups, facilitating the use of wider tires, which is particularly beneficial for gravel biking.

The SRAM DUB™ (Durable Unified Bottom Bracket) bearing series is created with one primary goal – to connect your crankarms and ensure smooth, long-lasting power transfer to your bike's drivetrain. To achieve this goal, SRAM developed the DUB™ spindle as the universal piece that fits all bottom bracket standards. This means one oversized spindle compatible with every bottom bracket standard. It leads to better crankarm compatibility, protection against dirt, dust, and water, longer-lasting performance, and a stronger, smoother, simpler construction.

Key Features:

• One oversized spindle to work across every bottom bracket specification.
• Significantly lighter than PFGXP system
• Easier installation by allowing you to press the bearing cups into the frame
• Size: 41 x 86.5mm
