Have these on my Boone on an Aeolus Pro 3 TLR wheelset. Mounting was pretty straightforward, I used Orange Endurance sealant. I had a slow leak in my front tire, but after a few rides the leak stopped. Ridden at 50psi, these are great on a well traveled dirt road, an old dirt and gravel road without smooth tracks or on pavement. I rode up a local mountain (in the Berkshires) after a rainstorm, so the dirt turned to mud but I didn't experience wheel slip or get stuck. I got the 35mm version, and thought initially I should have gone with the 40, but these have been fast, grippy, and great.
