I bought these tyres for my Specialized Diverge gravel bike for over the winter. I ride mostly on stoney/gravel farm trails and dirt trails which get rather mucky when the weather turns. I had the Specialized Pathfinder Pro's on before and whilst they are good in the summer, they did start to struggle when things got a bit wet and soft. I went for the Pirelli's in Gravel M and can't rate them highly enough. These tyres inspire a lot of confidence and keep the bike on track, they even roll well when back on the tarmac. It will be interesting to see if I bother taking them off when the weather gets better next summer.

I've been using these tires for about 6 months on all types of surfaces, from hard pack gravel roads, to loose and muddy singletrack. They provide excellent grip and thus far have proven quite durable. The riding in my area includes a fair bit of mountain bike trails with rock gardens, and they sidewalls have held up very well against repeated sidewall scrapes and scuffs. Only word of caution I'd have for prospective buyers is frame clearance. I have the 700x40mm version, and they mount up to 43mm wide on 24mm internal width rims. Many gravel frames have clearance for 45mm+, but not all.
