Bottom Brackets

$379.00 - $479.00
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
$379.00 - $479.00
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

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

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

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
