FAQs

What is the DUB spindle?

The DUB spindle is a 28.99mm axle that provides increased stiffness and durability. It's a key feature of the DUB system, ensuring better power transfer and compatibility across various bottom bracket standards.

Is the SRAM DUB Threaded Bottom Bracket compatible with my existing crankset?

No, it requires a DUB-compatible crankset. You will need to replace your existing crankset if it is not DUB compatible.

What tools do I need for installation?

You'll need a bottom bracket tool designed for threaded bottom brackets and a torque wrench to ensure proper installation.

How often should I service my DUB bottom bracket?

Service intervals vary depending on riding conditions. Inspect the bottom bracket regularly for any play or unusual noises. If you ride in wet or muddy conditions, you may need to service it more frequently.

What does the Gutter Seal Technology do?

Gutter Seal Technology enhances protection against the elements, preventing water, dirt, and other contaminants from entering the bearings, extending their lifespan.

Can I use the DUB bottom bracket on any frame?

No, the frame needs to have a standard threaded bottom bracket shell (BSA/English threaded) to be compatible.

What are the benefits of the DUB system?

The DUB system offers improved durability, better compatibility, and a stiffer, stronger, and lighter product compared to older designs.
