Enduro Bearings T47 Asymmetrical BB with XD15 Ceramic-Hybrid Bearings for SRAM DUB

The Enduro Bearings T47 Asymmetrical Bottom Bracket with XD15 Ceramic-Hybrid bearings is engineered to deliver unparalleled performance for SRAM DUB (28.99mm) spindle users. With a thread-in design and precision machined aluminium T47 cups, this bottom bracket offers an exceptional fit and durability. The use of 15-degree angular contact XD15 Pro cartridge bearings ensures smooth rotation and outstanding power transfer, making it a top choice for serious cyclists seeking longevity and reliability in their drivetrain components.

Manufactured in California with cutting-edge technology, these bearings combine corrosion-resistant, cryogenically treated nitrogen steel races with Grade 3 Silicon Nitride ceramic balls. This unique construction not only enhances performance by increasing contact area but also improves wear resistance, allowing the bearings to get smoother and faster over time. Backed by a lifetime warranty, the Enduro XD15 Pro bottom bracket sets a new standard for efficiency and durability in high-performance cycling.

The T47A asymmetrical threading standard featured in this bottom bracket offers compatibility with select high-end frames, including those from Cervelo and Factor, providing a secure and precise fit that enhances frame stiffness and pedaling efficiency. Enduro Bearings' extensive range of bottom brackets ensures a perfect solution for a wide variety of setups, with this model representing the pinnacle of their threaded bottom bracket technology.

What It’s Good For

• Providing ultra-smooth and efficient power transfer thanks to high-quality XD15 Pro ceramic-hybrid bearings
• Enhancing drivetrain longevity with corrosion-proof and wear-resistant bearing materials
• Offering a secure and precise fit with T47 asymmetrical threading for compatible frames
• Reducing maintenance needs through durable sealed LLB bearing seals and premium Kluber CRC Marine grease
• Improving pedaling performance by getting smoother and faster as the bearings wear in over time
• Supporting SRAM DUB cranksets with a perfect 28.99mm spindle interface
• Ensuring peace of mind with a full lifetime warranty against wear and corrosion

What It’s NOT Good For

• Frames or cranksets not compatible with the T47 asymmetrical threading standard
• Non-SRAM DUB spindle sizes or configurations that differ from 28.99mm
• Riders seeking a press-fit bottom bracket solution rather than threaded
• Applications requiring bottom brackets outside the specified XD15 Pro bearing performance range

Frequently Asked Questions

What makes the XD15 Pro bearings different from other ceramic-hybrid bearings?
The XD15 Pro bearings feature a unique 15-degree angular contact design with deep-groove raceways, allowing for larger Grade 3 Silicon Nitride ceramic balls. This increases the contact area for enhanced durability and smoother performance, which notably improves as the bearings wear in, unlike other bearings that degrade over time.

Is this bottom bracket compatible with all SRAM DUB cranksets?
This model is specifically designed for SRAM DUB spindles measuring 28.99mm, so it is compatible with cranksets that use this spindle size and T47 asymmetrical threaded bottom bracket shells.

Why choose a T47 asymmetrical bottom bracket over other standards?
The T47 asymmetrical threading offers a robust and precise fit that improves frame stiffness and pedaling efficiency compared to some press-fit or other threaded standards. It is favored by brands like Cervelo and Factor for its secure interface and ease of maintenance.

Does the bottom bracket require special maintenance?
Thanks to the sealed LLB bearing design and premium Kluber CRC Marine grease, maintenance is minimal. However, regular inspection for wear and cleanliness is recommended to ensure optimal performance and longevity.
