Been riding gravel for years using tradition oil based lubes -- this was 1st tested on a 60 mile ride that was 80% rain day -- chain was still doing great by end of day!
Squirt was recommended by several science based articles on friction. So far, it has worked flawlessly.
It isn't cheap, but amazingly quiet drivetrain and seems to be holding up better than things like White Lightening
Used this in mostly dry conditions on the road and gravel bike. Noticeable improvement in the drive train. I seem to apply more often, but I'd highly recommend.
