Real World Cycling BB30 Ceramic Hybrid AC Bottom Bracket
This bottom bracket is designed for cranks with 30mm spindles in a standard BSA threaded bottom bracket shell. It's ceramic hybrid angular contact bearings provide a stronger and smoother spinning bearing.
The balls are made from pure Silicon Nitride material with extreme high density from uniform compaction (3.25 g/cm3). The micro-structural development of this material during manufacture is second to none. These high precision Grade 5, SI3N4 pure ceramic balls are 5/1,000,000” from exactly round in sphericity. They are 60% lighter in weight, and 7 times harder than steel. Friction is reduced to near zero.
Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings. Angular contact bearings can carry both radial and axial loads. The weight of the load is transferred from one ring to the other, through the balls, along a specific contact angle.
Includes cup spacers, spindle spacers and a wave washer. Not all are required to be used but are included to ensure you have the parts you need to fit your crankset.
