Italian bottom bracket shells are typically only found on Italian bikes these days. They measure 70mm wide and have a 35mm inner diameter.
This package has the parts to install your 24/22mm crank into an Italian BB shell. This BB consist of bearings pressed into threaded cups, which are then threaded into the frame. Choose either CeramicSpeed 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 it even smoother and harder, resulting in longer life and lower drag.
The Standard Bearings have only 0.3-0.4 watts of frictional drag per set, an average drag reduction of 75% compared to stock bottom brackets. This is the result of superior design including hardened-steel races, and ceramic balls that are 100% smoother and 15% harder than the ceramic competition. They also last 3x longer.
Coated Bearings last even longer and feature even lower drag. Life is boosted by 60% and drag plummets by 50% compared to our Standard.
All Round Grease is used in the bearings. It can be replaced for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in the bearing when riding through messy conditions.
In The Box:
- 2 threaded cups with bearings installed
- 2 dust covers
