SRAM DUB BSA Bottom Bracket (68/73mm): A Revolution in Crankset Performance

Singular Focus for Unmatched Performance: The SRAM DUB BSA Bottom Bracket is at the forefront of drivetrain performance technology, with a straightforward yet critical mission: to seamlessly connect your crankarms while ensuring the smooth, enduring application of power to your drivetrain. SRAM's innovative approach has led to the creation of the DUB spindle, a component designed to unify and simplify the relationship between crankarm, spindle, and bottom bracket.

One Spindle to Rule Them All: The DUB (Durable Unified Bottom) technology represents a groundbreaking step in crankset design. By developing an oversized spindle that is compatible across all bottom bracket standards, SRAM has significantly enhanced crankarm compatibility. This universal approach not only simplifies the installation and maintenance process but also elevates the performance and longevity of your drivetrain components.

Engineered for Durability and Efficiency: Beyond compatibility, the SRAM DUB BSA Bottom Bracket is engineered for optimal protection against the elements. This design philosophy ensures that your drivetrain remains smooth and efficient, ride after ride, by shielding the bottom bracket from dirt, water, and debris. The result is a longer-lasting performance, reducing the need for frequent maintenance and part replacement.

Smoother, Stronger, Simpler: SRAM's commitment to strength, smoothness, and simplicity is evident in every aspect of the DUB BSA Bottom Bracket. By focusing on these core principles, SRAM has not only improved the overall riding experience but also provided riders with a bottom bracket solution that stands up to the demands of modern cycling, whether on the road, trail, or track.

Return to the Ride with Confidence: With the SRAM DUB BSA Bottom Bracket, cyclists can return to the ride with renewed confidence, knowing that their drivetrain is supported by a component that is built to last, perform, and simplify the cycling experience. The DUB technology is a testament to SRAM's dedication to innovation and excellence in the cycling world, ensuring that riders enjoy a stronger, smoother, and more reliable ride, every time.
