Best mid-sized bottom bracket for custom BMX crank installations.
This bottom bracket prioritizes precision and weight savings without overcomplicating your build. The highly machined spacers and adjustable center tube offer a custom fit for almost any crank setup, though the sheer number of included alignment shims means you will need to spend a little extra time dialing in your chainline.
