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 - Offered in a variety of types for better compatibility - 386 EVO 46mm Press fit, 30mm Spindle, 103gm, 86.5mm
Sealed and Delivered Bottom brackets are something you never think about until you do. With superior sealing and cable routing clearance, our 30mm Cinch BB92 will give you true peace of mind.

T47 threaded BB cups to run 30mm spindle cranks on T47 frames. Cups have outboard bearings and are typically used in BB shells with widths from 68mm to 100mm. Machined aluminum cups thread together directly into a T47 BB shell. Bearings are easily serviced or replaced. Includes sleeve to fit between cups for added protection from dirt and grime, and also keeps your internal wires and hoses from rubbing on the crank spindle. T47 BB cups are similar to standard BSA threaded cups in that the drive side cup is left-hand thread and the non-drive side cup is right-hand thread. Use a quality grease when installing in steel or aluminum BB shells, or a titanium-compatible anti-seize compound in titanium BB shells. - Bearings: Enduro Angular Contact - Bottom Bracket/Frame Interface: T47 - Bottom Bracket Shell Width: 68 – 100mm - Bottom Bracket Shell I.D.: 47x1.0mm Threaded - Over Bearing Width: 91.2mm in 68mm wide shell (dimensions include supplied silicone dust shields) - Tool Pattern: 44mm x 16-notch

BB90 is the Trek oversized bottom bracket standard and is only found on Trek road bikes. The shell is 90.5mm wide and is designed to work with 24mm spindles and road cranks and have the bearings inside the shell. The CeramicSpeed Bearings come as two bearings, which are then pressed into the frame. Those two bearings consist of either CeramicSpeed Standard or Coated Bearings. Both feature super smooth, super-round CeramicSpeed Balls contained in hardened-steel races. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in lower drag and longer life. -BB90 is simple and light. The standard is designed to work with 24mm spindles. The bearings work with Shimano and other 24mm cranks, like FSA. - The CeramicSpeed Standard Bearings last at least 3 times longer than other bearings. That's thanks to hardened-steel races and CeramicSpeed Balls that are 100% smoother & 15% harder than the ceramic competition. 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. - The CeramicSpeed Coated Bearings reduce drag by 50% compared to Standard Bearings and an improvement in bearing life of 60%. In The Box: - 2 BB90 bearings - 2 seals - 2 dust covers with integrated spacers - 10ml syringe of All Round 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

Italian-threaded bottom bracket shells are typically found on Italian-brand road bikes. The shell measures 70mm wide and has a 35mm inner diameter. This kit has all the pieces necessary to install 24mm diameter cranks, such as those from Shimano, FSA, and others into an ITA shell. CeramicSpeed bearings are pressed into threaded cups, then those cups are threaded into the frame. You choose whether you want yours equipped with Standard or Coated Bearings. Super-round, super-smooth CeramicSpeed balls rotate in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag. ITA BBs, thanks to the popularity of Italian road bike design, still have a following. The drive-side cup needs to be properly secured, but once that's done, the system is excellent. 24mm cranks work better when mated to our bearings. To make your bike as efficient as possible, you must reduce mechanical drag. Bottom brackets have a measurable effect on speed. CeramicSpeed balls are 100% smoother and 15% harder than the ceramic competition. They run on smoother races, too. That means our Standard Bearing BBs have 75% less drag compared to typical bottom brackets. And, the bearings last at least 3x longer than other bearings. These bearings come packed with All Round Grease. If you want less drag and are riding in cleaner environs, install lowest drag TT and Track Grease. If you're riding in wet conditions, more durable LongLife Grease can be put in. In The Box: - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10ml syringe of All Round grease - Sticker sheet
The PF30 standard is widely used. To make it compatible with Shimano and other 24mm diameter cranks, as well as improve the system, select this bottom bracket. The package comes with two cups and CeramicSpeed Bearings installed. The cups have extended inner sleeves and join with a center section, reducing the likelihood of creaking and increasing the reliability of the system while also eliminating spindle rub on internal cables. The cups mate with 24/22mm crank spindles. There are two bearing options. Both Standard and Coated Bearings feature super smooth CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated Bearings have an additional feature: a 3-micron thick metallic layer over the races. This addition makes the races smoother and harder, 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. The CeramicSpeed Coated Bearings last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our CeramicSpeed Standard Bearings. All Round Grease is installed in the bearings. It can be replaced 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 - 10ml syringe of All Round Grease - Sticker sheet
