Bottom Brackets

CeramicSpeed PF30A Bottom Bracket for SRAM DUB Road
$359.00
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 PF30A 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. Compatible with: - Frame: PF30A - Opening diameter: 46mm - Shell width: 73mm In the box: - 2 cups with CeramicSpeed Bearings installed - 2 dust covers - Spacer-tube - 4 x 1mm spacers - 2 x 3mm spacers - 10 ml syringe of CeramicSpeed All Round Grease - Sticker sheet
CeramicSpeed PF4130 Road and MTB Bottom Bracket
$359.00 - $459.00
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
CeramicSpeed PF4630 Bottom Bracket
$359.00 - $459.00
This bottom bracket is perfect for when you have a PF30, BBright, or 386EVO shell frame and want to install a crank with a 30mm spindle into the frame. All these frame standards have a 46mm inner diameter and smooth insides, though the widths vary from 68mm to 86mm. This bottom bracket features nearly zero loss of power due to friction, thanks to the CeramicSpeed's incredibly efficient bearings. Choose either our Standard or Coated Bearings—both have super-round, super-smooth CeramicSpeed balls rolling on hardened-steel races. The Coated version has a metallic coating laid onto the races, making them even harder and smoother and resulting in longer life and lower drag. They come installed in cups. 30mm spindles on cranks are increasingly popular because of the high stiffness and low weight. 46mm inner diameter bottom brackets are popular for the freedom they offer designers in building frames. Because of the variety of widths, the cups here extend into the shell and come with a telescoping spacer tube to further seal and stiffen the system. The bottom bracket is already stiff thanks to hard ceramic bearings and hardened-steel races. Thanks to CeramicSpeed, it also generates nearly zero drag. Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That's in the range of a 75% drag reduction versus conventional BBs. The bearings also last at least 3x longer than other bearings. You can change the grease to fine-tune your BB's performance characteristics. TT and Track, All Round, and LongLife are greases CeramicSpeed designed. The first has the least drag, while the last is the most durable. All Round, in the middle, comes standard in road bearings. In The Box - 2 cups with bearings installed - 2 1mm spacers - 2 0.5mm spacers - 2 dust covers - O-ring - Spacer tube - 10ml All Round Grease - Sticker sheet
CeramicSpeed BSA Bottom Bracket for Shimano Road
$379.00
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 works with 24mm diameter cranks, found on cranks from Shimano, FSA, Rotor, and others. Choose between two bearings 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. 24mm spindles easily fit through the shell and allow for large bearings to be employed in the outside cups. Put more of your energy into forward motion by reducing frictional drag wherever you can. 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. CeramicSpeed balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings. In The Box: - 2 threaded cups with bearings - 2 dust covers with built-in spacers - Spacer tube - 10mm syringe of All Round Grease - Sticker sheet
CeramicSpeed BB90 Bottom Bracket Trek SRAM GXP
$419.00
Trek developed their own BB standard to optimize their frame designs. BB90 has a 90.5mm shell width and 37mm inner diameter and is designed so that the bearings of external cups can hide within the frame. The CeramicSpeed kit comes 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 rotating in hardened-steel races. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in longer life and lower drag. - The BB90 standard is limited to Trek. This kit makes it possible for 24/22mm cranks from Quarq and SRAM to mate with your Trek. - The Standard Bearings last at least 3 times longer than other bearings. That's a result of hardened-steel races and ceramic 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 boasts an average 75% drag reduction compared to stock BBs. - The Coated Bearings increase bearing life by 60% and reduce drag by 50% compared to Standard Bearings. In The Box: - 2 bearings - 2 dust covers - GXP wave washer - Plastic cable protector - 10ml syringe of CeramicSpeed All Round Grease - Sticker sheet

CeramicSpeed BB92 Bottom Bracket for Shimano MTB
$459.00
The BB86 mountain bike standard was designed to integrate bearings into the bottom bracket for weight reduction. This kit works with the standard: it consists of two cups that are pressed into either side of the shell. There are two versions of this bottom bracket. Both come with CeramicSpeed Bearings installed into cups. The first is our long-life, low-drag Standard Bearing with hardened-steel races and our CeramicSpeed super-round, super hard balls. The second is our Coated bearing, which uses those same CeramicSpeed Balls installed on coated, hardened-steel races for longer life and less bearing drag. This CeramicSpeed BB86 Bottom Bracket meshes with cranks that have 24mm spindles, including both Shimano and FSA. CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That means an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature CeramicSpeed 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 drop friction further and increase lifespan to applying a coating to the races. The coated races see a 50% drag reduction and an improvement in bearing life of 60%. In The Box - 2 bottom bracket cups with bearings installed - 2 dust covers with integrated spacers installed - Spacer tube - 10ml syringe of LongLife Grease - Sticker sheet
CeramicSpeed BSA MTB Bottom Bracket
$459.00
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
CeramicSpeed BSA30 MTB Bottom Bracket
$459.00
BSA comes from Birmingham Small Arms, aka English threading. English threading on mountain bikes means 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 allows you to fit 30mm cranks, like those from Rotor or RaceFace, to fit in the tight space of this 30mm spindle. CeramicSpeed Coated Bearings are hand-built with unique CeramicSpeed Ceramic Balls installed on coated, hardened-steel races for longer life and less bearing drag compared to standard 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
CeramicSpeed ITA Bottom Bracket for Shimano Road
$459.00
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

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.
