Chain Juice Ceramic is an advanced chain lubricant that utilises cutting edge, ceramic additive technology to improve gear shifting performance. You should notice distinctly quieter, smoother and more â€œcrispâ€� gear changes when using Chain Juice Ceramic. The ceramic additive behaves in such a way that on a microscopic level it forms a laminar plate structure over the chain which greatly reduces metal on metal contact and therefore you enjoy better gear changes at all times, even under load when you shouldnâ€™t really be changing gear at all! You know the times â€“ when your gears normally create a noise that makes your face screw up??!
