Bottom Brackets

$123.99
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 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

The BB30 standard opened up design possibilities for frames. Adapting it for Shimano cranks takes a special machined aluminum threaded bottom bracket that threads into itself.
Ours are finished with CeramicSpeed Bearings. You have two choices in terms of bearings. The first choice is our low drag, long life standard bearing with hardened-steel races and our super-round CeramicSpeed Balls. The second choice is our coated bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag.
This bottom bracket works with cranks that have 24mm spindles.
Bottom brackets have several variables, but within that, 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 CeramicSpeed Bearings last at least three times longer than other bearings.
Coated Bearings see another big bump in performance. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.
Performance can be tuned by changing the grease. All Round Grease comes installed, but can be changed 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 installed
- 10ml syringe of CeramicSpeed 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 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

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 BB30 for SRAM DUB Road comes in two versions; one using our CeramicSpeed Standard Bearings and the other using our Coated Bearings for even longer lifetime and lower friction.

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
