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)
Very quiet. Feels super smooth. Only getting about 70 miles per application (gravel riding). Not as clean as I wanted. I am not sure The added cost is worth it. If I was a very fast rider, I would use it on race days.
This is only my second bottle but it definitely will not be my last bottle! Switched from a wet lube after always following my son around looking at his clean cassette and chain and hearing how quiet his shifts were. 95% of my rides are dry roads but I have been caught in the rain and Grax didn’t let me down. I’m picky about my stuff so I wipe the chain after every ride but clean and reapply after 250-300 miles. WD40 chain cleaner strips Grax off both the chain and cassette with ease so I get to ride around with a shiny chain and cassette too. Shiny stuff looks great against my Black frame. ;) Only mistake I made was not ordering 2 bottles with my repeat order!
I’m relatively new to gravel but GRAX is an obvious improvement over typical chain lube. Looking forward to its performance on my first race.
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.
