Then Sierra7 sealant should be included in your bicycle cleaning kit.

As the latest edition to our range of bicycle cleaning products, Sierra7 possess the ability to protect your bike’s frame and metal components against rust. In addition, the sealant reduces friction caused by the suspension, and creates a protective layer when applied over rubber and vinyl components. Sierra7 ensures protection against dirt, mud and sun damage. If applied properly, the sealant also serves as a bike polish, restoring your bike back to its original colour and providing it with a streak-free shine.
