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)

Waiting on Echo to try Grax.

I have about a month to wait for my new Echo to be delivered. Wanted to be ready to keep the drivetrain running smoothly.

Good stuff so far.

Probably too soon to tell

Have only put 150 miles on the lube, but it was rich/silky going on and survived epic mud in the Croatan BuckFifty.

Works Great!

But, kind of expensive. Works great, drivetrain is silent, and does last about 300 miles which is pretty damn good for gravel. Does not build up and leaves chain clean. I would recommend giving it a try and reserve it for gravel and XC rides.

Grax vs Sand Mud Snow

I try to ride all year, summer is easy, winter not so easy. I’ve tried several different chain lubricants and they were all pretty good but Grax is the best. I ride asphalt, gravel and dirt all on the same ride and Grax has performed the best for me. I don’t clean my chain as often as I should but Grax keeps working and let’s me get away with being a little lazy. Follow the directions for your fist application and I think you’ll be happy.
