Sram DUB BSA bottom bracket cups

SRAM DUB BSA Bottom Bracket Cups | 68/73mm

Elevate your MTB cycling experience with the SRAM DUB BSA Bottom Bracket, the cornerstone of modern drivetrain performance and reliability. Engineered to be the single, unifying component that simplifies your setup, the DUB (Durable Unified Bottom Bracket) system is a masterclass in engineering. It is designed to connect your crankset to the frame with unparalleled stiffness and longevity, ensuring every watt of power you produce is transferred directly to the trail. This bottom bracket isn´t just a part; it´s a fundamental upgrade for any serious mountain biker looking to optimize their ride.

The core benefit of the SRAM DUB system lies in its perfectly balanced approach. By creating a single oversized spindle diameter of 28.99mm, SRAM has found the sweet spot between the lightweight properties of smaller spindles and the stiffness of larger 30mm systems. This results in a bottom bracket that is not only incredibly robust but also impressively lightweight, helping you shed precious grams without sacrificing an ounce of durability. For the dedicated MTB cycling enthusiast, this means a more responsive, efficient, and reliable ride, whether you´re climbing steep technical ascents or descending at high speed.

Durability is paramount in the world of mountain biking, and the SRAM DUB BSA Bottom Bracket is built to withstand the harshest conditions. It features exceptionally well-sealed industrial-grade cartridge bearings, providing a formidable defense against water, mud, dust, and grit. This superior sealing technology significantly extends the life of the bearings, reducing maintenance intervals and giving you the confidence to ride hard in any weather. The smooth, low-friction performance of the bearings ensures your cranks spin freely, ride after ride.

Installation and compatibility are made simple. This BSA version is designed for the most common threaded bottom bracket standard, making it a straightforward upgrade for a vast range of mountain bike frames. It seamlessly integrates with all SRAM and Truvativ DUB cranksets, eliminating the guesswork and compatibility headaches that often plague bike builds and upgrades.
