Bottom Brackets

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 Wheels Mfg BB30 Outboard bottom bracket will give you all of the same benefits as their other Outboard style BBs.

BSA is equivalent to English threading. English threading on MTBs mean a 73mm-wide, 34mm-inside-diameter shell with reverse threading on the drive side. It's the most common threaded standard employed today. This kit works with 24mm diameter cranks, such as Shimano, FSA, Rotor, and others. Choose between two bearing types for the cups. Standard Bearings have low drag thanks to hardened-steel races and our Ceramic balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag. For MTBs, English threading, thanks to history, is pretty much the one threaded standard. It works great. 24mm spindles easily fit through the shell, allow for large bearings to be employed in the outside cups. What's more, they rarely creak and seal up well. Lots of things slow bikes down; bearings shouldn't be among them. 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. The bearings last at least 3x longer than other bearings. Coated bearings have even less drag. These bearings come packed with LongLife Grease, best for muddy conditions. For less drag when riding in cleaner environs, you can coat the bearings with either All Round Grease or lowest drag TT and Track Grease, which is designed for clean conditions.

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
