The FSA MegaExo bottom bracket features alloy cups, a composite center tube, and durable steel bearings. Designed for English threaded frames, this unit provides a stable interface for 24mm spindles, specifically compatible with pre-2014 Gossamer and Energy cranksets that use pinch bolts.
Due to specific manufacturer tolerances, MegaExo bottom brackets are designed solely for FSA cranksets and are not compatible with other brands. This model ensures precise fitment and alignment for the specific crank models it was engineered to support.
