Description

SRAM DUB T47 (68mm) – Road Bottom Bracket

The SRAM DUB T47 bottom bracket combines the durability and security of a threaded system with the stiffness and performance of a 28.99mm oversized spindle. Designed for frames with a 68mm T47 shell, this bottom bracket eliminates the creaking often associated with press-fit systems and offers superior protection against the elements thanks to Gutter Seal technology.

SRAM bottom bracket for T47 (Internal Bearing) standards with a 68mm shell. Designed for cranksets with a SRAM DUB spindle, it ensures smooth rotation, maximum debris protection, and unmatched ease of installation.

Detailed Features

• DUB™ Technology: The DUB (Durable Unified Bottom Bracket) standard unifies the spindle diameter to 28.99mm, allowing for a perfect mix of stiffness, lightweight design, and bearing longevity.

• T47 System: Leverages the benefits of an oversized bottom bracket shell but with a secure threaded fit, ensuring a stable and silent interface with the frame.

• Gutter Seal Technology: Advanced sealing drastically reduces friction while improving resistance to water and dirt, extending the life of the bearings.

• Precision Installation: Thanks to high-precision CNC machining, bearing alignment is perfect, reducing premature wear on your drivetrain.

FAQ - Frequently Asked Questions

• Is it compatible with GXP cranksets? No, this model is specifically for the 28.99mm DUB spindle. For GXP cranksets, a dedicated GXP bottom bracket is required.

• Can I install this on my Gravel bike? Yes, provided your frame's shell is the T47 standard with a 68mm width. If the shell is 73mm (MTB), a different specific model is needed.

• Is a special tool required for installation? Yes, installation requires a specific T47 bottom bracket tool compatible with the 12-tooth or 16-tooth standard (depending on the tool manufacturer).
