I've been using SCC lube most of the year, and have been happy with it, but decided to give the Grax a try. Application process is easy--it comes out of the bottle looking like Elmer's Glue, although a little more viscous. Run the chain backwards, and then through all your cogs, let it set for about an hour and you're ready to go. The Grax has held up nicely on my gravel rig during dry, dusty conditions for close to 300 miles. Quiet drivetrain and smooth shifting. It does a good job of shedding dirt, and I just brush the chain and cogs after rides. Grax has likewise held up well on my MTB, including a 30 mile rain soaked mudfest of a race. Highly recommended.
I use this for both my road bikes and gravel bike. It makes the drivetrain quiet and running buttery smooth. I used Squirt before and it washed off by just riding under sprinklers. Grax stays on.
Used for Gravel Worlds this year. Chain stayed clean and couldn't tell a difference in performance over oil. Very happy with it.
