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.
Fast, grippy, durable, easy setup. My favorite for a while now. Yes the Black Chili compound is worth it.
They work good - fast and traction - no punctures - but sidewall wear is real.
I use the Terra tires on gravel 1 & 2 levees and dirt roads as well as road group rides.
Best gravel tires I have ever ridden!! Great grip.
I have taken these tires off road and have been very impressed with traction. On road performance is pretty good too.
Not a ton of grip on loose stuff but they sure do roll fast. They also wear quick.
