MAINTENANCE FREE: the sealed cartridge bearing is maintenance-free and protects against dirt, mud and water. Suitable for a 68 mm case.
HIGH STRENGTH: The steel cover of the bicycle inner bearing absorbs the roundness tolerance for installing the lower connectors of the bracket.
INTEGRATED DESIGN: The BSA integrated system protects the frame and gives more power than a normal bottom bracket.
DURABLE: the bottom bracket is solid and durable with a long service time. Use the BB tool to safely install and replace the bottom bracket.
PRECISE DESIGN: the 68 mm bottom bracket has a fine workmanship, a small dimension error and a precise 2-bearing thread design that allows a better connection with the bicycle arm.
