      BSA Bottom Bracket MTB

      English-threaded bottom brackets are known as BSA; it comes from British Standard Cycle. English threading on MTBs 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 works with 24mm diameter spindle cranks, found on Shimano, FSA, Rotor, among others.

      The cups have CeramicSpeed bearings pressed in. The Coated Bearing has CeramicSpeed balls running on a 3-micron thick coating placed on top of hardened-steel races for greater durability and less friction.

      In The Box

TECHNICAL SPECIFICATIONS

Technical 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 Coated Bearings typically have frictional drag of 0.3-0.4 watts per set. That represents an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature the 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. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

These bearings come packed with Long Life Grease, best for muddy conditions. For less drag and are riding in cleaner environs, you can coat the bearings with either All Round Grease or lowest drag Race Day Grease, which is best in the clean conditions.
