Bottom Brackets

T47 threaded BB cups for T47 frames and 22/24mm spindle diameter SRAM and Truvativ GXP cranks. 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, and an anti-seize compound compatible with titanium BB shells.

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 EVO386 for SRAM DUB Road comes in two versions. The first version uses our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second version uses our Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag.

Why We Make It We build bearings, so we build bottom brackets. The humble threaded bottom bracket is often the first part installed on a new frame, and the last one the rider thinks about during the life of the bike, but the bottom bracket has a direct effect on pedaling efficiency (read: speed). This is where you put your power into the bike. Having the absolute best interface between your effort and your bike’s forward momentum makes your ride better. The Threadfit™ 24 is how we make bikes that take 24mm cranks the best they can be. Why You Want It ThreadFit™ 24 fits 24mm cranks in BSA bottom bracket shells. Our ThreadFit™ 24 bottom bracket is designed and built to be durable, serviceable, and silent. Manufactured to create the most precise interface between your frame’s bottom bracket shell and your cranks, it makes your cranks spin lightly and easily, without interference, for the lifetime of your bike (with a little regular service). King’s legendary, angular-contact bearings, both steel and ceramic, are the best in the industry, and actually get faster over time, as their contact surfaces wear. You want this bottom bracket because it offers super low drag. You want this bottom bracket, because it can be opened, cleaned and repacked for years of faithful service. You want this bottom bracket, because you don’t want to think an awful lot about your bottom bracket. Our Threadfit™ 24 bottom brackets come in an array of beautifully anodized colors and each one includes a Fit Kits that allow our ThreadFit™ 24 to be used with a wide selection of road and mountain bike cranks. - Engineered, manufactured and assembled in Portland, Oregon USA - King Lifetime Warranty - Legendary made-in-house bearings - Available in 8 beautifully anodized colors - A Fit Kit is required for use - Ceramic bearing upgrade available

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 first is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second 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: BSA - Opening diameter: Threaded - Shell width: 68mm 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 - Spacertube

The PF4130 bottom bracket is Press Fit into 41mm diameter shells that are 86.5mm wide and mate most cranks with a 30mm spindle to that standard. If you have a BB86 frame and want to install a 386EVO crank or Rotor 30mm crank, this is the kit you need. CeramicSpeed bearings are installed in cups. The Standard Bearing has ceramic CeramicSpeed balls and hardened-steel races. The Coated Bearing has the same balls running on hardened-steel races with a 3-micron-thick metallic coating making the races harder and smoother, increasing service life and reducing friction. Enjoying the benefit of a massive, strong, and light 30mm crank spindle in your BB86 frame is possible with this kit. Press in the cups, set up the wave washer, add spacers if necessary, and torque down. CeramicSpeed's bottom bracket is also stiff and light, but its greatest benefits come in the form of drag reduction. Standard Bearings with stock grease typically have frictional drag of 0.3-0.4 watts per set. That's about a 75% drag reduction compared to conventional bottom brackets. The bearings also last at least three times longer than other bearings. Performance can be tuned by replacing grease. All Round comes with this BB, but you can change it to TT and Track Grease for less drag or to LongLife for greater durability. In The Box - 2 cups with bearings installed - 2 1mm spacers - 2 0.5mm spacers - 2 dust covers - O-ring - Plastic cable protector - 10ml syringe All Round Grease - Sticker sheet
