Product Information
Full details
The Hope 29mm Bottom Bracket Conversion Kit (BB016-K1) is designed for mountain bike enthusiasts who use Hope 30mm bottom brackets and wish to upgrade or switch to SRAM DUB cranksets. Its primary benefit is providing a seamless, high-durability path to DUB compatibility without requiring a total bottom bracket replacement. The primary caveat is that this kit is specifically engineered for existing Hope 30mm bottom bracket systems and is not compatible with standard non-Hope brackets.

FAQs
Will this work with a non-Hope bottom bracket?
No, this conversion kit is specifically engineered to fit internal dimensions of Hope 30mm bottom brackets.
Does this change the chainline?
The adapter is designed to maintain standard SRAM DUB chainline requirements when used with compatible Hope bottom brackets.
Do I need special tools to install this?
Generally, standard shop tools like a torque wrench and crank installation tools are sufficient; no proprietary press tools are required for the adapter pieces themselves.
Can I use this for a 24mm spindle?
No, this kit is specifically for the 28.99mm SRAM DUB standard.
How often should I service the bearings after conversion?
Follow your existing Hope bottom bracket service intervals, which usually involve cleaning and re-greasing depending on trail conditions and weather exposure.
Troubleshooting
Creaking sound under heavy load
Remove the crank, clean the adapter and spindle interface, re-apply high-quality waterproof grease, and re-torque.
Difficulty inserting the crank spindle
Check that the adapter is fully seated and that the bearing inner races are clean and free of burrs or obstructions.
Pros and Cons
Pros
- Retains the high-quality bearing performance of original Hope bottom brackets
- Cost-effective solution to upgrade cranks without replacing the entire bottom bracket
- High-precision tolerances prevent crank-arm movement and creaking
- Genuine Hope component ensures reliable compatibility
Cons
- Strictly compatible only with existing Hope 30mm bottom bracket models
- Requires proper removal of existing 30mm spacers or sleeves
- Not intended for non-Hope bottom bracket brands
Setup, Compatibility & Care
To install, ensure your current bottom bracket is a Hope 30mm unit. First, clean the internal surfaces of the bottom bracket bearings thoroughly to remove old grease or debris. Slide the adapter components into place following the specific orientation provided in your Hope BB manual. Use a high-quality waterproof bike grease on the mating surfaces to prevent oxidation and creaking. Compatibility is limited specifically to Hope 30mm systems and SRAM DUB 28.99mm crank spindles. Regular care involves checking the crank preload collar periodically to ensure no lateral play has developed, and cleaning the outer seals during standard drivetrain maintenance.
