Bottom Brackets
$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

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

The EVO386 standard is designed for oversized spindles. CeramicSpeed's kit for Shimano allows you to install Shimano or FSA cranks with 24mm spindles.
The cups come with CeramicSpeed Bearings installed. Both CeramicSpeed Standard and Coated Bearings are available. Both utilize super smooth CeramicSpeed Balls and hardened-steel races. The latter has an additional metallic coating on the races to further smooth and harden the steel, further increasing life and lowering drag.
The design of overlapping cups extending through the shell for EVO386 reduce the likelihood of creaking and increase the reliability of the system.
The CeramicSpeed Standard Bearings feature an average drag reduction of 75% compared to stock bottom brackets. That translates into frictional drag of 0.3-0.4 watts per set, which is the result of great design, hardened-steel races, and ceramic balls that are 100% smoother and 15% harder than the ceramic competition.
The CeramicSpeed Coated Bearings are a step up as they reduce drag by 50% compared to our Standard Bearings and an improvement in bearing life by 60%.
All Round Grease comes standard in the bearings, but 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

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 ITA for SRAM DUB Road comes in two bearing options. The first option is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second option 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: Italian BB
- Opening diameter: Threaded
- Shell width: 70mm
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

The PF30 standard has opened design possibilities for mountain bikes. Our CeramicSpeed PF30 Shimano MTB Bottom Bracket gives you the ability to install Shimano and other 24mm diameter spindle cranks on your PF30 MTB.
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.
Performance can be tuned by changing the grease. LongLife Grease comes installed, but can be changed for lower-drag All Round Grease for lower drag and cleaner riding conditions.
In The Box
- 1 bottom bracket with CeramicSpeed bearings installed
- 2 dust covers
- 5 0.85mm spacers
- 10ml syringe of LongLife Grease

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.

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™ 30 is how we make bikes that take 30mm cranks the best they can be.
Why You Want It
ThreadFit™ 30 fits 30mm and DUB spindle cranks in BSA bottom bracket shells.
Our ThreadFit™ 30 bottom bracket is silky smooth and long-lasting thanks to our legendary, angular-contact bearings, both steel and ceramic, the best in the industry. They actually get faster over time as their contact surfaces wear, because we build them to ultra-tight aerospace tolerances, using machined, Delrin-spindle sleeves to create a perfect, and precise fit between cranks and frame. That’s where the low drag and butter smooth feel come from.
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™ 30 bottom brackets come in an array of beautifully anodized colors and each one includes a Fit Kit that allows it to be used with a wide selection of road and mountain bike cranks.
The Fit Kit for our ThreadFit™ 30 with 30mm spindle cranks is available here. The Fit Kit for DUB cranks is available here.
ThreadFit 30 comes with a Center Sleeve for 73mm BB shell. For 68mm shell - sleeve PBB082 is required(included in Fit Kit #2 for DUB Road cranks).
