CYCLINGCERAMIC bottom bracket BSA for SRAM DUB | red
Founded in 2012 by French cyclist Héloise Proust, Cyclingceramic is committed to ensuring that every watt you put on the pedals is converted into propulsion. At their company headquarters in France, they manufacture high-quality ceramic ball bearings for a wide range of bike components by hand. The company relies on sourcing all components from European suppliers. In addition to individual ball bearings, the French also produce a large selection of oversized derailleur cages, derailleur pulleys and bottom brackets to help you improve your performance on the bike. Convinced of the high quality of their products, Cyclingceramic gives you a 4-year guarantee on their bearings.
With the Cyclingceramic bottom bracket you can improve the efficiency of your crankset. The silky-smooth running of the bearings enables better power transmission when pedaling. The Cyclingceramic bearings were also able to prove this on the renowned Friction-Facts test bench, where they were on a par with the best tuning bottom brackets. Thanks to their manufacture from high-quality materials, they can withstand even the most adverse conditions.
Ceramic bearings
The ceramic balls used by Cyclingceramic are made from high-quality grade 3 silicon nitride. Compared to conventional steel balls, they are 58% lighter, 12% harder and 68% stiffer. In addition, the roundness is 75% higher. The outstanding properties of the ceramic balls not only reduce frictional resistance to a minimum, they also make the bearings more durable. At Cyclingceramic, each ball is precisely inserted by hand into the hardened steel raceways manufactured in Switzerland. The balls are held in place by lightweight, corrosion-resistant polyamide cages. The non-contact seals reduce frictional resistance and still protect the bearings against the ingress of dirt and moisture. During the production process, each bearing is checked several times to ensure that all components fit perfectly.
The bearing grease included in the scope of delivery is used for maintenance and has been specially adapted to these bearings. Lubricants from other manufacturers are not recommended.
NOTE: DUB bottom bracket spacers are not included in the scope of delivery. You can find the right spacer kit for your SRAM DUB crank in our store.
