Overview
English-threaded bottom brackets are known as BSA; it comes from British Standard Cycle. 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 spindle cranks, found on Shimano, FSA, Rotor, among others.

The cups have one of two bearings installed. 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 lower mechanical friction.

In The Box

• 2 threaded cups with bearings.
• 2 dust covers with built-in spacers.
• Spacer tube.
• 10mm syringe of LongLife grease.
• Sticker sheet

Tech data:
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, rarely creak, and seal up well.

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%.

LongLife Grease comes installed, but can be changed for lower drag All Round Grease, which is fine for less extreme conditions.

CeramicSpeed Bottom Brackets
The CeramicSpeed Bottom Brackets guarantee you the lowest friction, optimised power transfer, and longest product lifetime, helping you to save watts or ride faster. Fitting almost all standards available on the market, more than 150 types of CeramicSpeed Bottom Brackets are available for upgrading your bike. Choosing to upgrade with a bottom bracket with coated bearings, you benefit from even further reduced friction and better resistance to contamination and corrosion.

CeramicSpeed Bottom Bracket Compatibility
The CeramicSpeed Bottom Brackets covers 99% of all cranks brands and models in the market, from Shimano to SRAM and Campagnolo. Some of the latest additions to the CeramicSpeed Bottom Bracket product range are the SRAM DUB compatible Bottom Brackets that covers almost all compatibilities. 

Bottom Brackets for road, MTB and triathlon
No matter the discipline, there’s a CeramicSpeed Bottom Bracket that fits. The Bottom Brackets come in both road, tri and MTB specific variants. Use the CeramicSpeed Bottom Bracket Fit Finder to find the right fit for your specific crank. Among the CeramicSpeed Bottom Brackets specifically designed for MTB cranks are CeramicSpeed BSA30 MTB, CeramicSpeed PF4630 MTB, PF30 for Shimano MTB, PF30 for SRAM GXP MTB and many more. 

Coated Bottom Brackets for even better performance
All of the CeramicSpeed Bottom Brackets come in a coated version for even longer lifetime and lower friction. The coating on the Bottom Brackets is a thin metallic layer that is 75% harder than the hardened-steel races and which offers an even better performance than the non-coated CeramicSpeed Bottom Brackets.
