A chain lube so efficient, it's won the Tour De France - twice. Yes, this is the ultimate, all-weather formulation that has helped Team Sky take home the yellow jersey at the world's most prestigious cycling event two years in a row. We're so proud of this fact that, for a limited time only, all our Team Sky Hydrodynamic Lubes will be available in a commemorative yellow packaging. We've even reformulated the lube itself to match the colour of the winner's jersey! Each application can last up to 400 miles on the chain and withstand the harshest of weather conditions, proven by hundreds of hours of in-house testing. We've even infused the recipe with an ultra-violet dye, so you can see exactly what parts of your chain have and have not been lubed under a UV light - which comes included! Behold the lube of champions. And now you can get your hands on it too.
