This bottom bracket prioritizes long-term reliability over lightweight trends, using angular contact bearings that actually handle the abuse of mountain biking. It’s a mechanic’s favorite because it’s fully serviceable, meaning you can keep it running smoothly for years rather than just replacing it when the grit inevitably wins.
