Miche Evo Max MCBB202 BB30 24mm Bottom Bracket - 68 42mm Developed to install a compatible 24 mm Miche chainset in a BB30 frame, the Evo Max MCBB202 provides a complete bearing and cup interface without requiring a separate threaded adaptor. The system presses into a 68 mm wide frame shell with a 42 mm internal diameter. Its integrated bearing cups position the sealed cartridge bearings to support the narrower 24 mm chainset spindle correctly within the oversized BB30 shell. CNC-machined 7075-T6 aluminium construction provides the dimensional accuracy required for secure press-fit installation while keeping weight controlled. The sealed bearings help resist water and contamination, supporting smooth operation with reduced routine maintenance. This model is dimension-specific. A frame described only as “press fit” cannot be assumed compatible: both the 68 mm shell width and 42 mm shell diameter must be confirmed. Features Allows a compatible 24 mm Miche chainset to be installed in a BB30 frame. Integrated design combines the bearing and conversion interface in one assembly. CNC-machined 7075-T6 aluminium cups provide accurate press-fit engagement. Sealed cartridge bearings help protect the rolling surfaces against contamination. Wide bearing support helps maintain drivetrain stiffness under pedalling load. Purpose-built dimensions avoid reliance on loose spindle-reducing adaptors. Compatibility Compatible with: BB30 frames with a 68 mm wide bottom bracket shell. Frame shells with a 42 mm internal diameter. Compatible Miche chainsets using a 24 mm spindle and requiring an Evo Max Bottom Bracket. This model is not intended for PF30, BB86 or BB386EVO frames. Compatibility with third-party 24 mm chainsets should be verified against the chainset manufacturer's dimensional requirements. Specifications Feature Specification Manufacturer Miche Product code MCBB202 Frame standard BB30 press fit Shell dimensions 68 42 mm Shell width 68 mm Shell diameter 42 mm Spindle diameter 24 mm Cup material CNC-machined 7075-T6 aluminium Bearing type Sealed cartridge bearings Weight 116 g Technical Notes Installation requires a suitable bearing press with correctly sized drifts. Do not drive the cups into the frame using a hammer or apply force through the bearings. The frame shell should be clean, accurately sized and free from damage before installation. Incorrect alignment during pressing can damage the cups or frame shell. Professional installation is recommended for all press-fit Bottom Brackets.
