Bottom Brackets

The Wheels Mfg BB30 Outboard bottom bracket will give you all of the same benefits as their other Outboard style BBs. The two machined aluminum cups thread together ensuring the bottom bracket remains stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement. Specifically designed for installing 24mm spindle diameter cranks (Shimano, FSA, Etc.) in BB30 frames without the need for adapters. - Bearings: Enduro ABEC-3 - Color: Red - Bottom Bracket/Frame Interface: BB30, Specialized Alloy OSBB - Bottom Bracket Shell Width (mm): 68mm - 73mm - Bottom Bracket Shell I.D.: 42mm - Crank Spindle Type: Shimano Hollowtech II, FSA MegaExo, RaceFace EXI - Crank Spindle Diameter: 24mm - Weight: 130g

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. 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. CeramicSpeed hand-built bearings carry the load from crank to frame with unparalleled durability & efficiency. 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. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the product. The ITA for SRAM DUB Road comes in two bearing options. The first option is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second option is our Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag. Compatible with: - Frame: Italian BB - Opening diameter: Threaded - Shell width: 70mm In the box: - 2 cups with CeramicSpeed Bearings installed - 2 dust covers - 4 x 1mm spacers - 10ml syringe of CeramicSpeed All Round Grease - Sticker sheet - Spacer tube

The BB30 standard opened up design possibilities for frames. Adapting it for Shimano cranks takes a special machined aluminum threaded bottom bracket that threads into itself. Ours are finished with CeramicSpeed Bearings. You have two choices in terms of bearings. The first choice is our low drag, long life standard bearing with hardened-steel races and our super-round CeramicSpeed Balls. 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. This bottom bracket works with cranks that have 24mm spindles. Bottom brackets have several variables, but within that, CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That's in the range of a 75% drag reduction compared to standard bottom brackets. That's thanks to balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings. Coated Bearings see another big bump in performance. The coated races see a 50% drag reduction and an improvement in bearing life of 60%. Performance can be tuned by changing the grease. All Round Grease comes installed, but can be changed for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in the bearing when riding through messy conditions. In The Box: - 1 bottom bracket with bearings installed - 2 dust covers installed - 10ml syringe of CeramicSpeed All Round Grease - Sticker sheet

The PF30 standard has opened design possibilities for mountain bikes. Our CeramicSpeed PF30 Shimano MTB Bottom Bracket gives you the ability to install Shimano and other 24mm diameter spindle cranks on your PF30 MTB. Our PF30 cups have extended sleeves and join with a center section, reducing the likelihood of creaking and increasing the reliability of the system. There is both a Standard and Coated version. Both feature super smooth CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated Bearings have an additional benefit: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, lowering drag and increasing life. The CeramicSpeed Standard Bearings have only 0.3-0.4 watts of frictional drag per set, an average drag reduction of 75% compared to stock bottom brackets. This is the result of great design, including hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer. If you want longer life and even lower drag, opt for the CeramicSpeed Coated Bearings. Life increases by 60% and drag drops by 50% compared to our CeramicSpeed Standard Bearings. Performance can be tuned by changing the grease. LongLife Grease comes installed, but can be changed for lower-drag All Round Grease for lower drag and cleaner riding conditions. In The Box - 1 bottom bracket with CeramicSpeed bearings installed - 2 dust covers - 5 0.85mm spacers - 10ml syringe of LongLife Grease - Sticker sheet
