CeramicSpeed's quest in reducing bicycle friction for cyclists is evident in how many different bottom bracket/crank spindle offerings it has on tap. Reducing drivetrain friction at the crank is pretty much the first line of defense in nixing additional drag and if your frame uses a BB86 shell and you're running a Shimano 24mm-style spindle crank, we'd like to make a suggestion for you. Pressfit86 shells allow for wider bottom bracket/downtube junctions boosting frame stiffness and without metal threads, the setup usually comes in a bit lighter. And we all know that adding stiffness while dropping weight is the holy grail, the trifecta is dropping friction too and now you can purchase the same components that the pros count on to get an edge on the competition. CeramicSpeed is an industry-leader in smooth rolling bearings and the BB86 Shimano bottom bracket allows you to take full advantage of the improved power transfer and lightweight design afforded by BB86 with the silky smooth spinning of those famous ceramic ball bearings. Enjoy increased speed at the same effort, or save up the watts for a race winning move with this bottom bracket. The Coated version uses the same CeramicSpeed balls, however, they're installed on coated, hardened-steel races for even more durability and a further reduction in friction.
Reducing friction not only saves watts, allowing you to ride faster with less effort, it helps the component last longer. The Danes at CeramicSpeed are downright obsessive in its quest to reduce friction which is why it offers bottom brackets for almost every standard on the market. And if you loathe friction as much as the crew at CeramicSpeed does and want to optimize your bike to go as fast as possible with the least amount of effort, upgrade your bike with one of its bottom brackets and enjoy reduced friction as well as better resistance to contamination and corrosion. CeramicSpeed is so certain in the durability of the Coated version that it extends its warranty 2 more years over its standard version for a total of 6 years.
Compared to standard steel ball bearings, CeramicSpeed's balls resist corrosion, which is in part responsible for why bearings start to feel gritty as they age as well as causing the bearings to run hotter, reducing the lifespan of the component. CeramicSpeed balls are also much harder than standard steel balls. Apply enough pressure to a steel ball and it will crack under load while under that same load the CeramicSpeed ball won't flinch, maintaining the exact surface finish and roundness which affects spinning smoothness. Meanwhile, these non-round and rough ball bearings create increased friction and begin to quickly wear down the bearing races.
CeramicSpeed is able to achieve such high marks because it uses the highest quality Grade 3 Silicon Nitride for its bearings. Don’t be fooled into thinking that all ceramic bottom brackets bearings on the market are the same. In testing, CeramicSpeed claims its balls are 15% harder, can take 99% higher loads, and are more than 100% smoother than other ceramic balls typically used on the market. Included with the bottom bracket are dustcovers, special grease for maintenance, and a sticker sheet.
