This high-quality bottom bracket features a forged & CNC-machined alloy construction, which allows it to handle all the intensity that's associated with long days in the mountains. FSA has also equipped this model with ceramic bearings for minimum friction & maximum durability. Another highlight is its alloy centre with double O-ring seals, which keeps dirt out. Weighing in at only 108g, this is a great choice of upgrade for riders who want a tough component for tough rides.
