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\\n2 threaded cups with bearings.\\n2 dust covers with built-in spacers.\\nSpacer tube.\\n10mm syringe of All Round Grease.\\nSticker sheet.\\nFrame \\u0026amp; Axle: External \\/ standard 24mmThread: BSAColor: BlackMaterial: AlloyBearings: CS 61805 coatedCrank Compatibility: Shimano, FSA, Rotor a.o. 24mm
