PF30A is a Cannondale-specific standard for their 73mm wide bottom bracket shells. This CeramicSpeed kit makes it possible to install Shimano and other 24mm diameter thru-axle cranks into a Cannondale frame. CeramicSpeed Bottom Brackets guarantee you optimised power transfer, the lowest friction and longest product lifetime, helping you to save watts and ride faster. Fitting almost all standards available on the market, a wide range of CeramicSpeed Bottom Brackets is available for upgrading your bike. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag. The coating on the Bottom Brackets is a thin metallic layer that is 75% harder than the hardened-steel races and which offers an even better performance than the non-coated CeramicSpeed Bottom Brackets. Put more of your energy into forward motion by reducing frictional drag wherever you can. CeramicSpeed Standard Bearings typically have frictional drag of 0.3 - 0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. CeramicSpeed balls are 100% smoother and 15% harder than our ceramic competition. Our bearings last at least three times longer than other bearings. Race Day Grease, All Round, and Long Life are greases CeramicSpeed designed to maximise smoothness. The first offers the least drag, the latter is the most durable. All Round comes as standard in road bearings, Long Life in MTB. You can change the grease to further tune performance. The Coated Advantage The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results. Within our comprehensive R&D program, the special coating has been developed in cooperation with a European coating specialist. Applied to the bearing’s steel races, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of CeramicSpeed Bearings. Thanks to the coating’s high resistance to corrosion – even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible. We recommend choosing CeramicSpeed Coated Bearings for unmatched longevity and incredibly low friction.

The Story CeramicSpeed is one of the world’s leading suppliers of ceramic bearings. The company consists of two specialised sales channels, focusing on cycling and industrial applications. We have more than 15 years of experience in bearings applications, and we have developed close relationships with our component suppliers over the time – each of whom is the very best in their fields. The CeramicSpeed Sports channel delivers both bearings as well as ultrafast racing chains, reinforcing the company’s goal of saving watts and delivering the lowest friction available. All our bearings are handmade and our chains are optimised by hand in Denmark.
