描述
For Cross, Mountain, or rainy muddy environments, 440C stainless steel can be a great choice to cut down on maintenance and weather the stormy rides to come. This material will not rust or corrode, and to help them last, we use a 4 mm diameter ball that has +50% mass compared to the competition. We also offer this bearing in Angular Contact design especially for Bottom Brackets to stand up to the axial loads from pedal forces.
