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.
