Long days riding gravel can make it nearly impossible to keep things clean well-lubricated and running fast. To counter this we partnered with a spin-off from the University of Arkansas Nanotechnology Department to create a high performance chain lube and cleaner called GRAX. The results are in. Dirt or pavement rain or mud slop or muck GRAX keep riders rolling faster longer. GRAX is short for gravel wax. It is a wax-based lube engineered to shed water dirt and mud and keep chain rollers well lubricated and running smooth through endless miles of abuse. We tested GRAXs efficiency vs. several competitors in standard dry conditions as well as the nasty stuff. After countless hours in labs and four full seasons of riding gravel roads and trails around northwest Arkansas we found GRAX to be the most efficient and most durable lubricant on the market. We tested two primary performance properties in GRAX 1) it's ability to repel moisture and 2) wattage expenditure in both dry and muddy conditions. GRAX was tested against multiple experimental hydrophobic lubricants as well as the most expensive and high performing products on the market. GRAX excels in all categories. It ensures you not only have the most efficient lube available it also sheds water and dirt better than any product. It shaves watts keeps your drivetrain running smoothly and quietly for more miles in the most extreme conditions and improves the longevity of your drive train components.
