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)
Goes on without leaving a mess, and really cleans the drivetrain while you ride. I am a big fan of wax based lubes - GRAXX works great on all my MTBs. Wet or dry riding - full send!
I've got to say I am impressed. I'm almost 400 miles into one application, and it's still feeling smooth and quiet as if there's a fresh layer of lube. I think I've found a favorite chain lube.
While I know many of the reviews here are from veteran professional mechanics, this review is from someone who's mechanical ability doesn't not extend past tire pressure checks and wacks on the down tube with an adjustable wrench so the derailleur shifts smoothly. But nonetheless I took to GCL like it was second nature, an immediately noticable improvement in performance from the first ride to my last right. The Grax chain lube is now on evey one one of my bikes.
I am very meticulous about riding a clean bike and literally will not start a ride if my chain makes crunchy sounds from lube picking up dust granules. I have been very impressed with GRAX and have made the switch on all of my bikes.
Love the GRAX cleaner and lube.I have used this in my cyclocross, enduro, and eMTB. The emtb is really hard on chains and sprockets so if you are getting dry, you will hear it. This is the best I’ve used n dry and wet conditions. Highly recommend!
