Between the chain, sprocket, and chainring, there is constant friction during riding, as well as between the chain links. This leads to fine metal abrasion, causing the chain to inevitably become dirty. Together with residues from chain lubricants, sand, road dirt, etc., a stubborn coating forms on the chain, sprocket, and chainring, which significantly accelerates wear. New lubrication becomes increasingly ineffective as the lubricants can no longer penetrate the chain. The solution to this problem is the F100 Chain Cleaner. The F100 Chain Cleaner is formulated to provide perfect adhesion during application and to develop its high creeping properties while it works. This gel formula ensures thorough, self-acting, and fast cleaning of the bicycle chain. Additionally, the chain cleaner provides corrosion protection and is completely acid-free, posing no risk to any surfaces.
