SRAM DUB BSA Ai MTB Bottom Bracket Cups: The Ultimate Foundation for Your Cannondale Ai Drivetrain
Elevate the heart of your mountain bike´s drivetrain with the SRAM DUB BSA Ai MTB Bottom Bracket Cups, meticulously engineered for riders who demand uncompromising performance, durability, and a perfectly integrated system. Designed specifically for Cannondale frames featuring the innovative Asymmetric Integration (Ai) drivetrain, this bottom bracket is the key to unlocking flawless shifting, superior power transfer, and long-lasting reliability on the most demanding trails.
The core of this system is SRAM´s revolutionary DUB™ (Durable Unified Bottom Bracket) technology. This groundbreaking approach simplifies the complex world of cranksets and bottom brackets by creating a single, unified standard. The DUB system revolves around a 28.99mm spindle, striking the perfect balance between the lightweight properties and stiffness of oversized 30mm spindles and the enhanced bearing longevity found in 24mm systems. The result is a “best of both worlds” solution that delivers robust stiffness for explosive accelerations and technical climbs, while ensuring the bearings remain smooth and protected for countless miles of aggressive MTB cycling.
Unmatched Durability and All-Weather Performance
Mountain biking pushes components to their limits, exposing them to mud, water, dust, and grit. The SRAM DUB BSA Ai Bottom Bracket is built to thrive in these harsh conditions. It features exceptionally high-quality sealed cartridge bearings that are shielded from the elements, preventing contamination and ensuring a consistently smooth and friction-free pedal stroke. This focus on sealing significantly extends the service life of the bottom bracket, reducing maintenance and keeping you on the trail longer. You can ride with confidence, knowing your bike´s core is protected, season after season.
Engineered for Asymmetric Integration (Ai)
This is not a standard BSA bottom bracket. It is precision-made for Cannondale´s unique Ai drivetrain offset. The Asymmetric Integration design shifts the drivetrain outward to allow for a stronger, stiffer rear wheel and massive tire clearance. These specific DUB BSA Ai cups are essential to establish the correct chainline required for this system, guaranteeing crisp, precise shifting and optimal drivetrain efficiency. By choosing the correct Ai-specific component, you ensure that your entire drivetrain works in perfect harmony as the engineers intended.
Key Benefits:
