The second choice is our coated bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag. The first choice is our low drag, long life standard bearing with hardened-steel races and our super-round CeramicSpeed Balls. You have two choices in terms of bearings. Ours are finished with CeramicSpeed Bearings. Adapting it for Shimano cranks takes a special machined aluminum threaded bottom bracket that threads into itself.
The BB30 standard opened up design possibilities for frames. 10ml syringe of CeramicSpeed All Round Grease 2 cups with CeramicSpeed Bearings installed
Bottom Bracket Tool for installation: BBT-79 The BB30 for SRAM DUB Road comes in two versions one using our CeramicSpeed Standard Bearings and the other using our Coated Bearings for even longer lifetime and lower friction. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the product. The SRAM DUB crank spindle requires the bearing contact points to be in a set and designated width and all CeramicSpeed bottom Bracket options perfectly match the bearing placement on the crank spindle with the required frame interface for nearly any model of bike. CeramicSpeed hand-built bearings carry the load from crank to frame with unparalleled durability & efficiency. With an integrated dust cover for all models, the snug & secure fit not only fully protects the face of the bearing, but also delivers exceptional performance without any sacrifices. The new SRAM DUB crank standard, built on a 28.99mm spindle, allows for a more contamination-resistant BB design while retaining the ultra-efficient & long-lasting qualities CeramicSpeed Bottom Brackets are known for. The CeramicSpeed Coated Bearings reduce drag by 50% compared to Standard Bearings and an improvement in bearing life of 60%. These bearings have a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to stock BBs. That's thanks to hardened-steel races and CeramicSpeed Balls that are 100% smoother & 15% harder than the ceramic competition. The CeramicSpeed Standard Bearings last at least 3 times longer than other bearings. The bearings work with Shimano and other 24mm cranks, like FSA. The standard is designed to work with 24mm spindles.
The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in lower drag and longer life. Both feature super smooth, super-round CeramicSpeed Balls contained in hardened-steel races.
Those two bearings consist of either CeramicSpeed Standard or Coated Bearings. The CeramicSpeed Bearings come as two bearings, which are then pressed into the frame. The shell is 90.5mm wide and is designed to work with 24mm spindles and road cranks and have the bearings inside the shell. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads, and are 100% smoother.īB90 is the Trek oversized bottom bracket standard and is only found on Trek road bikes. CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel bearings normally used in the bicycle industry. The benefits are super low friction, better power transfer, and increased bearing life.ĭuring the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cross, and MTB. Non-contact seals complete the bearings, keeping dirt and moisture out. Every bearing is optimized with a low-viscosity CeramicSpeed All Round Grease to minimize friction and increase bearing life. The balls are held in place by a reinforced polyamide cage. Super-smooth CeramicSpeed grade 3 Silicone Nitride balls are matched (within microns) with hardened steel raceways that feature an ultra-smooth polished groove. All CeramicSpeed Bearings are hand-built in Denmark.
