Bottom Brackets

Bottom brackets from FSA for non-threaded applications. - 24mm spindle compatibility - Stainless steel bearings - Spindle Interface Type: FSA MegaExo - BB Shell Width: 92mm - Bottom Bracket Shell I.D.: 41 - BB/Frame Interface: BB92

Bottom Brackets are an essential part of the bicycle that is often overlooked and forgotten, but we saw the BB as another opportunity for performance gains and improved efficiency. For our BB we have developed a seal that achieves a very low level of drag while still retaining excellent protection qualities. Its thinner and low viscosity bearing grease with the correct fill level offers higher durability at high speeds. If you’re running the best crankset on the market, you should have the performance BB to match. - Thinner and lower viscosity bearing grease for higher durability at high speeds - In-house testing procedure includes developing a 24-hour continuous water invasion test - BB86 41mm Press fit, 30mm Spindle, 66gm, 86.5mm

This rock-solid, durable performer is everything you need in a press-fit 24mm bottom bracket and nothing more. Roll on...and on...and on.

Rock The BB Precise fit, smooth-rolling operation, long-living performance–what more can you ask for from a bottom bracket?

BBright is the Cervelo bottom bracket standard found on most of their frames, save the P5. In order to fit Shimano and FSA cranks into this oversized shell, this bottom bracket, complete with CeramicSpeed Bearings, needs to be pressed in. The BBright bottom bracket comes with either CeramicSpeed Standard or Coated Bearings installed. Super smooth, super-round CeramicSpeed Balls contained in hardened-steel races are found on both versions. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in lower drag and longer life. BBright is similar to BB30, but is wider on the non-drive side. As such, the bottom bracket for running 24mm diameter cranks from Shimano, FSA, and others, is unique. The CeramicSpeed Standard Bearings last at least three times longer than other bearings. Thanks goes to hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. These have a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to most BBs. The CeramicSpeed Coated Bearings reduce drag by 50% compared to CeramicSpeed Standard Bearings, and show an improvement in bearing life by 60%. In The Box - 1 bottom bracket with bearings installed - 2 dust covers - 10ml syringe of All Round Grease - Sticker sheet

The BB30 bottom bracket allows you to pair 30mm spindle cranks to 42mm inner diameter bottom bracket shells. Cannondale pioneered this standard along with specially-designed cranks and many have found the benefits to them. Road versions have a 68mm width, MTB has 73mm. These are also the bearings you can use to replace bearings in PF30 cups. You have two bearing choices. 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. BB30 was designed to make the bike lighter: no cups, threading, or redundant metal, plus a lighter, stiffer crank. That's why the crank spindle is 30mm, which was a big jump up from square-taper spindles. 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 bearings last at least three times longer than other bearings. In The Box - 2x bearings - 2x 1mm spacers - 2x 0.5mm spacers - 2x dust covers - O-ring - 10ml syringe of grease - Sticker sheet

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. In The Box - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10ml syringe of LongLife grease - Sticker sheet

BSA is another way of stating English threading. The initialization comes from Birmingham Small Arms, which made bicycles. English threading on road bikes mean a 68mm-wide, 34mm-inside-diameter shell with reverse threading on the drive side. It's the most common threaded standard employed today. This kit allows you to fit 30mm cranks, like those from Rotor, to fit in the tight space of this 34mm spindle. Choose between two bearings types for the cups. Standard Bearings have low drag thanks to hardened-steel races and our CeramicSpeed Balls. Coated Bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag. Note that the threaded extensions of this BB's cups that thread into the frame are thin, as they need to fit a 30mm spindle inside the cups. 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 bearings last at least 3x longer than other bearings. In The Box: - 2 threaded cups with bearings installed - 2 1mm spacers - 2 0.5mm spacers - 2 dust covers - O-ring - 10ml syringe All Round Grease - Sticker sheet - Spacertube
