The bottom bracket is a key component of every chainset. Smoothness movement is critical, yet must be balanced by enough sealing technology to sustain a reasonable lifetime of use. FSA MegaExo bottom brackets are the result of years of development and feature exclusive innovations to guarantee the best balance of efficiency and durability. FSA uses state-of-the-art materials like Silicon Nitride-formed ceramic ball bearings, or highly polished chrome steel ball bearings, depending of the level of the bottom bracket.
