- for optimal performance, replace the chain. We highly recommend adding 2 to 4 additional stitches. Aluminum pulleys have reduced wear compared to standard plastic pulleys. The dry cushions completely in ceramic, protected by aluminum roofs, guarantee longer duration. They have been designed so that we should not worry about maintenance or technical problems. During use, dirt can infiltrate the roofs and bearings; You can remove it with water or an degreaser. The bearings are completely in ceramic (cage and spheres), so there is no risk of oxidation.
