FAQs
What type of cranksets is this bottom bracket compatible with?
This Miche Evo Max bottom bracket is designed for cranksets with a 24mm axle diameter.
What frame bottom bracket shell size does this fit?
It fits frames with the BB30 standard, specifically a 68mm shell width and 42mm diameter.
Can I use this on both Road and Mountain Bikes?
Yes, the design is suitable for both Road and MTB applications.
Are the bearings user-serviceable?
The bearings are sealed for protection. While they are robust, they are not designed for user servicing. If they become damaged or excessively worn, the entire bottom bracket unit is typically replaced.
How do I know if my frame is BB30?
A BB30 frame shell is typically 68mm wide and has an inner diameter of 42mm. It does not have threads inside the shell. You can usually find this information in your bike's specifications or by measuring your frame.
What is the weight of this bottom bracket?
This specific model (BB30 68 x 42) weighs 116 grams.
Troubleshooting
Stiff or grinding bearings
This may indicate contamination or wear. While sealed, aggressive riding in wet or dirty conditions can impact performance. Replacement of the bottom bracket may be necessary.
Bottom bracket creaking
Creaking can often be resolved by ensuring the bottom bracket cups are properly torqued in the frame and that the crankset spindle is correctly installed. Cleaning and re-greasing the spindle interface can also help.
Incorrect fit with frame
Ensure your frame has a BB30 standard shell measuring 68mm width x 42mm diameter. This bottom bracket is not compatible with BSA, Press-Fit, or other bottom bracket standards.

Setup, Compatibility & Care
Compatibility:
This Miche Evo Max Bottom Bracket is specifically designed for frames with a BB30 standard shell measuring 68mm in width and 42mm in diameter. It is compatible with cranksets featuring a 24mm axle diameter. Please verify your frame's bottom bracket shell dimensions and your crankset's axle diameter before purchase.
Setup:
Installation of the Miche Evo Max Bottom Bracket typically requires specialized tools for pressing the cups into the frame and for tightening. It is recommended to have this component installed by a qualified bicycle mechanic to ensure proper fitment and to prevent damage to the bottom bracket or the frame.
Care:
To maintain optimal performance and longevity:
- Regular Cleaning: Wipe down the external surfaces with a damp cloth after rides, especially if exposed to mud or dirt.
- Bearing Check: Periodically inspect for any grinding or stiffness in the bearings. While sealed, extreme conditions can affect performance over time.
- Avoid High-Pressure Washing: Do not use high-pressure washers directly on the bottom bracket seals, as this can force water or contaminants past the seals.
