SRAM - Bottom DUB Road MTB BSA 68/73 mm

Description

SRAM DUB Bottom Bracket | BSA 68/73 mm

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:

• Universal design: The large spindle provides excellent compatibility with all bottom bracket specifications, allowing you to use this bearing with various bikes.
• Moisture and dirt protection: Gutter Seal Technology™ ensures that bearings are protected from external factors, extending their service life and reducing the need for maintenance.
• Lighter than GXP®: While being lighter, this bearing remains sturdy and reliable, giving the bike more efficiency.
