Thanks abc. I have limited gravel tire experience and my last 2 years have been on VeeRubber Rails (700x40) with Orange seal. They have been durable and worn well, but always felt a tad sluggish. I was getting them free, so I just used them..
The MSO seems to tick the boxes I want, but I keep reading how heavy they are. I’ve been running the new Michelin rubber on my trail bike and like the grip of the Gum-X rubber in the wet. That wet grip drew me to look at the Michelin Gravel options, but minimal people running them.
