    Fast and Supple

    These tires are a little expensive but well worth the cost. The 700x36 is pretty spot on with the claimed weight and they measure just shy of 38mm on mavic all road pro wheels. On the pavement they are quiet, smooth and fast. On gravel they are grippy, fast and confidence inspiring in the curves. The tacky rubber compound does pick up more sand from the roads I ride but nothing major. They set up tubeless easily with a lezyne floor pump. So far they have very little wear with about 200 miles and I am hard on tires.

    Great Gravel Tire

    Bought this after riding the Maxxis Rambler - this tire is great on road and gravel - very fast on each surface and runs tubeless as well.

    Thin casing, fast

    Expanded about 3mm on 20mm internal hubs. Still great for gravel and wet roads.

    Great tire for the big gravel rides!

    This is by far my new favorite gravel tire, great on dry gravel conditions, I have yet to dry it in the wet, but I suspect it will be great too.
