Black Ops 19mm Euro MX Bottom Bracket – Silver

The Black Ops 19mm Euro MX bottom bracket allows a Euro-threaded frame to run MID-style BMX cranksets with a 19mm spindle. It’s a conversion solution for frames that have threaded Euro shells but where the crank choice is built around MID-style spacing and components.

This is commonly used when updating or mixing BMX parts across different frame standards without changing the frame itself.

Service / Ownership Context
Spacing and bearing placement matter with conversion bottom brackets. During installation, chainline and crank clearance should be checked carefully. Proper torque and correct spacer setup are key to avoiding bearing preload issues or crank side-load.
