CeramicSpeed BSA Road Coated Bottom Bracket – Black

Bsa is another way of stating english threading; it comes from british standard cycle. English threading on road bikes mean a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. Its the most common threaded standard employed today. This kit works with 24mm diameter thru-axle cranks, found on shimano, fsa, rotor, among 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.

In the box

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