PF30A is a Cannondale-specific standard for their 73mm wide bottom bracket shells. This CeramicSpeed kit makes it possible to install Campagnolo and Fulcrum Ultra-Torque cranks on PF30A Cannondale frames.

CeramicSpeed Bearings come loose for crankarm attachment and sit inside the included cups once mounted. There are versions with Standard and Coated Bearings. Both have super round CeramicSpeed Balls and hardened-steel races. The Coated have an additional attribute: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, lowering drag and increasing life.

Features

The unique PF30A shell is 73mm wide with a 46mm diameter. Ultra-Torque cranks seat the bearings on the inside of the crankarms. A removal/installation tool is necessary; we sell one here, but any appropriate tool will work. 

0.3-.04 watts of friction is the 'cost' of our Standard Bearings. That's a drag drop of 75% compared to stock bottom brackets. This is the result of great design: hardened-steel races combined with ceramic balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer. 

Coated Bearings last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% versus our Standard. 

All Round Grease comes applied to the bearings from the factory. It can be replaced for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in when riding through messy conditions.

Coated bearings

CeramicSpeed's coating has several performance enhancing properties that makes it unique. Thanks to their continuous R&D program, CeramicSpeed have developed a special coating in cooperation with a European coating specialist. Applied to the steel races of the bearing, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of the CeramicSpeed bearings.

Low friction Once coated, the bearing races deliver a hardness level matched only by the CeramicSpeed balls, providing an extremely low friction coefficient between the two materials. The result is thus even less friction in their coated bearings than in their standard bearings.

Coating Graf Friction - 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. As CeramicSpeed use a metallic coating on top of the hardened steel, it can be difficult to see that a bearing is actually coated. However, if you take a closer look at a coated bearing, you will notice that the surface has a different shine than a standard CeramicSpeed bearing.

Lifetime - The coating has several properties that improve the lifetime of CeramicSpeed's bearings. The increased hardness of the races combined with the super smooth and round CeramicSpeed balls, means virtually no wear on the bearing.

The coating layer is applied completely closed and homogenous. The formula used for the coating is extremely resistant to corrosion. This means that even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible.

Your favourite 24mm spindle cranks can now be improved with the lowest drag bottom bracket.

The CeramicSpeed PF30 Shimano Road Bottom Bracket features low friction CeramicSpeed Bearings and benefits from the unmatched lifetime, guaranteed by the highest quality materials used in the manufacturing of this product.

CeramicSpeed Coated Bearings match the unique properties of CeramicSpeed Balls with even further reduced friction and extended lifetime. 

How to achieve the optimal performance - The coated bearings are more resistant to lack of lubrication when it comes to wear and damage on the bearing nonetheless, this does not mean that the need for maintenance is completely eliminated. Just as CeramicSpeed do with their standard bearings, they recommend to always lubricate them with our special grease to achieve optimal performance in terms of low friction and long lifetime. For all training and racing applications they recommend the use of CeramicSpeed Blue all-round grease. If you want to achieve the lowest possible friction, CeramicSpeed recommend you to use their TT grease. Please be aware that compared to the standard Blue all-round grease, the TT grease has a shortened lifetime and therefore, it requires more frequent application.

Handmade in Denmark Like all other CeramicSpeed bearings, their coated products are handmade in Denmark. This means all bearings are built by hand and inspected manually at each step in the production process. Building a coated bearing adds a number of extra steps to the process. The CeramicSpeed balls and steel races are matched within microns after which, each set of races is coated. The races are kept together in pairs through the entire process and after coating, each set needs to pass the quality control before they go into production.

CeramicSpeed coated bearings are available for pulley wheels, bottom brackets, wheel bearings and the Oversized Pulley Wheel System.
