ITA SRAM DUB Road
Sure, press-fit has found a home on the market, and taken hoards of Italian steeds along with it, but there are still some exceptionally crafted Italian bikes that we covet for their precision-threaded Italian bottom brackets that offer creak-free support through the miles. Despite our love for the threaded bottom bracket, one issue that recently rose up from the tarmac comes when you want to pair your lovely ITA bottom bracket with SRAM's newest DUB cranksets. Until now options have been few and far between for the 28.99mm spindled crank, but CeramicSpeed offers a solution that not only marries your Italian Threaded bottom bracket with a DUB crankset, but does so with friction-dropping ceramic bearings on the ITA SRAM DUB Road bottom bracket.
Reducing friction not only saves watts, letting you 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 and want to optimize your bike to go as fast as it can, upgrade your bike with one of its bottom brackets and enjoy reduced friction as well as better resistance to 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 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.
