Replaced stock Bontrager tires on a Trek 920 ("Adventure Touring / Super Gravel Bike") for off-road/gravel/mixed surface/bike packing rides. LOVE these tires. Super quality you and I would expect from Maxxis. Rolling resistance on paved paths/roads is really great but the tread pattern gives enough bite for dirt and gravel. Excels at all-around, "multi-surface" rides. I run them tubeless with Stan's and they are flawless overall and easy to get on/off my DT Swiss rims. I purchased black wall, 120 TPI, SilkShield version. The 29x2.0 size may be a bit much for some "gravel bike" folks I get it but it is awesome for my bike and super clydesdale stature. Easily able to handle some low tech singletrack too. They were great on a recent multi-surface bike packing trip with 45+ lbs of extra gear/panniers front and rear. The tire's size at 700x50x is clearly a MTB sized tire but the extra "cush" and stability is superb IMHO. Highly recommend.
This is a very durable long lasting tire. I have 1,600 miles on my current set that are showing very little wear. I find this pretty remarkable in that they are on Trek Rail eBike that gets about half of its miles on pavement as I ride to and from the mountain bike trails from my house. Low rolling resistance on pavement, great bite on the dirt. I run the DHF on the front and rear.
I swap these tires in when I know I'll be riding on some rugged gravel roads. The only Issue I have is that while my frame can handle them my SRAM Red eTap front derailleur can't. The outermost drive side tire lugs are wearing a groove into my eTap battery. I ground down this row of lugs with a file, but they still rub so I leave the bike on the small chainring, remove the front battery, and ride my bike as a 1x11 when these are mounted. None of this is the tire's fault, but check the clearance on your bike before buying.
