GXP Ceramic Italian Bottom Bracket

The SRAM DUB Italian Bottom Bracket is the premium solution for integrating SRAM's lightest and stiffest cranksets into frames featuring a traditional 70mm Italian-threaded shell. By utilizing DUB technology, this system unifies the relationship between the spindle and bearings to deliver superior drivetrain performance and longevity.

Elite Construction: This model features high-performance ceramic sealed cartridge bearings housed in precision-machined aluminum cups. This combination provides incredibly low rolling resistance and significant weight savings compared to previous GXP systems, making it the ideal choice for high-end road builds.

Advanced Weather Protection: Equipped with Gutter Seal Technology, this bottom bracket is engineered to withstand the elements, effectively sealing out grit and moisture. The result is a durable, smooth-spinning interface that maintains a 45.5mm chainline, ensuring crisp shifting and reliable power transfer on every climb.
