- Designed to get that suspension running smoother than butter is our new Silky Suspension Serum. This suspension specific, silicone infused wonder formula reduces the stiction between wiper seals and stanchions, keeping everything lubricated to help with small bump sensitivity and trail buzz. It even helps to repel muc (k) and grime, keeping surfaces cleaner and reducing the risk of contaminants getting into the wiper seals and ruining both your fork oil, and your ride!
