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 GRAX’s 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.

GRAX is available in a 4oz bottle (up to 20 applications)

Good for dust, wet and dry

I’ve been using Grax chain lube for well over a year now (maybe longer) in less than ideal (pouring rain and mud), dusty dirt and gravel, to clean pavement. I’ve had zero issues with this lube not performing. I use it on my gravel bike, my son’s gravel bike and his mountain bike. It hss never failed us and with two different riders we both see only normal chain wear. In fact, I got nearly 4700 miles out of my last chain which I only used Grax on.

This is one of the best chain lubes I have ever used. It does collect dirt. It repels water. I raced the Leadville 50 on Sunday and put it on before the race, and my chain never made a sound. It is still going strong. I have used a lot of different chain lubes and this is the cleanest, best working chain lubes I have found.

Second year of using GRAX love it

Works great, keeps my drivetrain humming and is not nearly as messy as other options. Love it
