The Bombshell ceramic bottom bracket is light, durable and makes your cranks spin fast. It is the result of years of research into making the best BB. After carefully working with the bearing manufacturer we feel that we have created the ultimate Euro BB. It uses big 12mm wide (10mm is standard) ceramic bearings to better reduce ball load. These ultra-precision ceramic bearings were designed in Germany to the highest standards and use a custom formulated waterproof grease to ensure that the BB will roll smoothly for 10,000 miles!
