ROTOR Bike Components has developed a specific BB30 & BBright crankset based on its successful 3D crank, to be the perfect 100% compatible with any BB30 or Classic BSA threaded frame (using special ROTOR "BSA30" BB cups) on the market!. ROTOR 3D+ crank: a light-weight, purebred performance aluminium crank: 476 g for 170/130 BCD (w/o BB and chain rings).
3D+ cranks have an improved version of our proprietary "Trinity Drilling System" technology. Due to the larger axle-crank contact area of a BB30 crank, all three holes can be drilled from the axle side of the crank arm, allowing for further optimization of wall thicknesses, improving both the weight and the weight-rigidity ratio of the crank arm.
