The Sugino BB-SG75 SUPER CERAMIC Bottom Bracket is a high-end cup-and-cone bottom bracket designed for premium track and fixed gear drivetrain setups. Made by Japanese brand Sugino, it has been trusted by many professional riders and competitive cyclists.
The BB-SG75 SUPER CERAMIC uses a traditional cup-and-cone structure, allowing precise adjustment for an exceptionally smooth feel. This design is also easier to maintain, helping the bottom bracket perform reliably over long-term use when properly installed and serviced.
It features high-grade, high-precision ceramic ball bearings made in Japan. These ceramic balls help reduce friction when turning the crank, making them especially effective under high-load racing conditions where drivetrain efficiency matters.
The spindle and cup races receive Sugino’s SUPER LAP special polishing treatment, creating a smoother and more durable contact surface. Combined with the ceramic ball bearings, this produces an extremely smooth and long-lasting rotation feel.
The SG75 series uses Sugino’s patented SG75 taper spindle design, so SG75 cranksets must be used with SG75 bottom brackets. Installation also requires the specified Sugino spindle bolts to ensure proper crank and bottom bracket fitment.
