Enduro Angular Contact bearings are specifically designed for hubs and bottom brackets. Enduro ABEC-5 Angular Contact Bearings are an improvement over radial bearings as every ball is in contact with the races during load. This spreads the force of pedaling across a larger surface area which in turn decreases friction and helps minimize wear. Dual lip groove seals made of silicone help keep water and other contaminants out. Machined aluminum shell threads together for precise bearing alignment and frame fit, reducing bottom bracket creaking and premature bearing wear. Angular contact ball bearings are particularly suitable for carrying combined axial and radial loads. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.
