Ceramic Speed Botton Bracket for SHIMANO Black Coated - BB ITA Shimano

BSA for Shimano Road

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. It’s 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.
-All Round Grease.
-Sticker sheet.


ITA for Shimano Road
Italian-threaded bottom bracket shells are typically found on Italian-brand road bikes. The shell measures 70mm wide and has a 35mm inner diameter.

This kit has all the pieces necessary to install 24mm diameter spindle cranks into an ITA shell. Those cranks come from Shimano, FSA, and others.

CeramicSpeed bearings pressed into threaded cups, then threaded into the frame. Those bearings comprise either Standard or Coated Bearings. Super round, super smooth CeramicSpeed balls rotate in hardened-steel races in both. The Coated version has a metallic coating laid onto the races, making them even harder and smoother, resulting in longer life and lower drag.

In The Box:
-2 threaded cups with bearings.
-2 dust covers with built-in spacers.
