Miche Evo Max Press Fit 68 x 46 mm [PF30]

Miche Evo Max MCBB203 PF30 24mm Bottom Bracket – 68 × 46mm

Designed for PF30 frames, the Evo Max MCBB203 provides the bearing and conversion interface needed to install a compatible Miche chainset with a 24 mm spindle in a 68 × 46 mm press-fit shell.

The integrated assembly locates the sealed cartridge bearings securely within the oversized frame shell. This supports the narrower chainset spindle across a stable bearing stance, helping maintain drivetrain alignment and efficient power transfer under load.

CNC-machined 7075-T6 aluminium cups provide the accuracy required for dependable press-fit engagement. Bearing seals help keep water and contamination away from the rolling surfaces, supporting smooth operation and reduced maintenance.

PF30 and BB30 use different shell diameters. This 46 mm model must not be substituted for the 42 mm MCBB202, even though both versions are intended for a 68 mm wide shell.

Features

• Connects a compatible 24 mm Miche chainset with a PF30 frame.
• Integrated bearing and conversion design creates a secure drivetrain interface.
• CNC-machined 7075-T6 aluminium cups provide precise press-fit installation.
• Sealed cartridge bearings help resist water, dirt and drivetrain contamination.
• Stable bearing placement supports accurate spindle alignment under load.
• Purpose-built 46 mm fitment avoids improvised or loosely fitted adaptors.

Compatibility

Compatible with:

• PF30 frames with a 68 mm wide bottom bracket shell.
• Frame shells with a 46 mm internal diameter.
• Compatible Miche chainsets using a 24 mm spindle and requiring an Evo Max Bottom Bracket.

This model is not compatible with 42 mm BB30 or 41 mm BB86 shells. Compatibility with third-party 24 mm chainsets must be checked against the chainset manufacturer's requirements.

Specifications

Technical Notes

• Installation requires a suitable bearing press with correctly sized 46 mm cup drifts.
• Apply installation force to the cups rather than through the bearing races.
• The frame shell should be clean, accurately sized and free from damage.
• Both cups must enter the frame squarely to prevent damage or poor alignment.
• Professional installation is recommended for all press-fit Bottom Brackets.
