CeramicSpeed delivers unmatched performance in key areas of your bike.
CeramicSpeed Bottom Bracket which fits BB86 Shimano press-fit frames and standard 24 mm spindle cranksets like Shimano.
Fits frame shells with a 41mm inner diameter. This product also fits BB91 and BB92 standards based on frame with. Availability covers standard or coated bearings, with red or black cups.
Check out their Bottom Bracket Compatibility Matrix if you are in doubt about the right fit for your bottom bracket.
Bottom bracket bearings and BB86 aluminium cups are assembled by hand ensuring the best quality standards are achieved.
Please note that this BB86 bottom bracket cannot be used for GXP cranks. A specific GXP compatible bottom bracket is available separately, for both road and MTB.
Available with either standard or coated bearings. The advantage of the coated bearings relies on the special layer of coating, which strengthens the bearings’ lifetime and reduces the friction to the minimum.
Handmade in Denmark and BB86 alumiunium cups are machined locally in Denmark.
Offers extremely low friction and longer lifetime.
Ceramic balls - are of the highest achievable quality and out-perform everything else in the market.
Spacers - are of high quality and they are not soft or create any creaking sound.
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 our 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.
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.
