nduro Bearings invented, designed and formulated polyurethane wipers for the mountain bike fork. Standard designs are plagued by “stiction” contamination and quick degradation of overall performance. Enduro Bearings signature Blue Polyurethane wipers solve these problems, upgrading performance in all of these areas, especially smooth performance over long periods without maintenance. They keep the dirt out and the oil inside. Enduro Bearings wipers seal better, move faster, are slicker, last longer, and run quieter than stock wipers. And now coming with Moly Disulphide lubricated lower oil seals, your forks will move quicker still while never leaking a drop of oil. Available for most major brands and models of suspension forks at substantial savings and improvement over stock wipers
