SRAM DUB PF30 Bottom Bracket Shell 46x83 mm MTB Cannondale

The SRAM DUB PF30 46x83 mm bottom bracket is designed to ensure maximum power transmission efficiency, offering reliability, durability, and compatibility with SRAM DUB cranksets. Developed specifically for MTB Cannondale frames with a PF30 46x83 mm bottom bracket shell, it represents the ideal solution for achieving high performance on every ride.

SRAM DUB technology was created with a precise goal: to connect the cranks and ensure smooth and consistent power transmission to the drivetrain. The heart of the system is the oversized DUB spindle, designed as a unifying component to work with all major bottom bracket specifications, improving compatibility with SRAM cranksets.

The innovative relationship between spindle and bearings is the strength of DUB technology, where stiffness and durability work together to offer a more efficient pedal stroke. Furthermore, increased weather protection helps preserve performance over time, even in the most demanding conditions of use.

Thanks to an approach focused on developing a complete system, SRAM has optimized the integration between the chainring, crank, spindle, and bottom bracket, improving the overall efficiency of the drivetrain and ensuring a smoother, more durable, and simpler pedalling experience.
