Product Information
Full details
The Praxis M30 Bottom Bracket is the essential hardware for cyclists aiming to install Praxis M30 road cranks into a 386EVO road frame. It delivers a robust, high-performance interface through precision-machined aluminum cups and high-quality steel cartridge bearings, ensuring smooth power transfer for demanding riders. Potential users should be aware that this specific unit is strictly limited to Praxis M30 spindle-based cranks and is not compatible with universal 30mm spindles or the Verve InfoCrank M30.

FAQs
Will this work with my 30mm spindle crank from another brand?
No. The Praxis M30 bottom bracket has a specific stepped configuration (30mm drive side / 28mm non-drive side) and will not accommodate standard 30mm spindles.
Can I use this with a Verve InfoCrank M30?
No, this bottom bracket is explicitly not compatible with the Verve InfoCrank M30 due to differences in the interface shape.
What is the shell diameter required for this unit?
This unit is designed for a 386EVO frame, which has a shell diameter of 46mm.
Is this a press-fit or threaded bottom bracket?
This is a press-fit style bottom bracket designed for 386EVO frames.
How often should I service the bearings?
Service intervals depend on riding conditions. In dry, clean conditions, annual inspection is sufficient, but more frequent cleaning is recommended if riding in wet or muddy environments.
Troubleshooting
Creaking noise under load
Ensure the bottom bracket cups are fully pressed and seated flush against the frame shell. Use a high-quality bicycle-specific anti-seize or grease on the cup interfaces.
Crank does not fit
Verify you are using a genuine Praxis M30 spindle crankset. Confirm the frame shell is a 386EVO standard (86.5mm width) and not a different BB30 or PF30 variant.
Increased friction when pedaling
Check that the dust covers and seals are properly seated and that there is no debris trapped between the spindle and the inner bearing race.
Pros and Cons
Pros
- Specifically engineered for high-precision Praxis crank fitment
- Durable machined aluminum construction resists deformation
- Smooth and reliable steel cartridge bearings
- Easy installation process within 386EVO shells
Cons
- Not compatible with generic 30mm spindle cranks
- Does not support Verve InfoCrank M30 systems
- Strictly limited to the 386EVO frame standard
Setup, Compatibility & Care
Installation requires a professional-grade press tool to ensure the aluminum cups are seated evenly within the 46mm diameter 386EVO shell. Always ensure the shell is clean and free of debris before pressing in the cups.
Compatibility Note: This bottom bracket is built exclusively for Praxis M30 spindles. It is not compatible with standard 30mm spindles (like those found on SRAM or Rotor cranks) because the bearing seat diameters are different.
Care Instructions: To extend the life of the steel bearings, perform a periodic cleaning of the crankset area to remove grit and grime. Avoid using high-pressure water sprayers directly on the bearing seals, as this can force contaminants inside the cartridge, leading to premature wear.
