PF30 SRAM DUB Road
Enjoy a smoother spinning drivetrain and maximum friction reduction by taking a page out of the pro teams' book and go with a CeramicSpeed bottom bracket. Reducing friction at the crank is the first line of defense in nixing drivetrain drag and if your frame uses a PF30 shell and you're running a SRAM DUB crank, its PF30 SRAM DUB Road bottom bracket is the one you need. The PF30 standard allows for a larger diameter (46mm) bottom bracket shell, boosting frame stiffness and without metal threads, the setup usually comes in quite a bit lighter. Besides the added stiffness and gram dropping of the PF30 shell, by reducing bearing friction, you can ride for longer and faster with less effort. CeramicSpeed is an industry-leader in silky-smooth rolling bearings and its PF30 DUB bottom bracket allows you to take full advantage of the more contamination resistant DUB BB design while retaining the ultra-efficient and long-lasting qualities CeramicSpeed Bottom Brackets are known for.
Reducing friction not only saves watts, allowing you to ride faster with less effort, but it also 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 and want to go fast with fewer watts lost, upgrade your bike with one of its bottom brackets and enjoy reduced friction as well as better resistance against contamination and corrosion.
Compared to 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 which reduces 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 could affect spinning smoothness. Meanwhile, these non-round and rough ball bearings create increased friction and begin to quickly wear down the steel bearing races.
CeramicSpeed is able to achieve such top 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.
