 Tripeak, as a bearing manufacturer in Taiwan, uses the best materials and greases in its steering box bearings.
 There is no entry line for this type of bearing. The simplest model is already made of chrome steel, for greater material resistance.
 Steering box bearings are always designed with a double seal and the largest possible balls, which rotate in a small cavity, aiming to achieve maximum protection against sweat and other contaminants. 
Additionally, 90% of the bearings are filled with high-pressure waterproof grease, avoiding any questions regarding lubrication.
