Details / CeramicSpeed BSA SRAM GXP MTB alternative Red Coated
Threaded MTB bottom brackets are mostly English-threaded, aka BSA, and feature the same threading and the same 34mm inner diameter, but a wider 73mm shell. This kit pairs SRAM and Quarq 24/22mm spindle cranks to the BSA MTB standard.
Bearings pressed into threaded cups, which are then threaded into the frame are the main components of this kit. Those bearings consist of either CeramicSpeed Standard or Coated Bearings. Super smooth, super round CeramicSpeed balls are rotating in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in longer life and lower drag.
