Surprised you see pitting coming through if you are greasing it? What are you greasing it with? Specialist chain lube or just grease? I've used to use the ceramic chain wax which is "low fling" and stays on quite well, and recently I've moved to Wurth dry lube in an aerosol which is clear. Seems to work quite well, but you do need to reapply it from time to time - preferably AFTER you have been out unless you leave a few hours between applying and riding. You'll do well to get it replaced though, it's a consumable item. |
