These tires are faster and lighter than knobbies and you can feel the difference. Perfect for taking your MTB on long gravel rides. But they are not as robust as full knobbies, I rode them on a rugged technical trail and one failed catastrophically with a 2" rip in the sidewall. It's not the tire's fault, they weren't designed for that kind of abuse. That said, I've put hundreds of gravel miles on these and they've proven great traction and no flats, more robust than Schwalbe G-One Allrounds which gave me no end of problems.
Overall recommended, if you stick to gravel and don't take them on terrain that is too rough.
I got these tires to ride my MTB on long gravel rides. Knobby tires have great traction & durability, but their weight and rolling resistance isn't ideal for gravel rides. I weighed these tires at 550 gr each in 47-650 size (1.85" wide). That's 250-350 grams lighter than knobbies. I run them tubeless and they fit perfectly, though did require a compressor to seat and seal.
Previously I ran Schwalbe G-One Allrounds but they got so many flats I had to try something else.
Kudos to BikeTiresDirect for having them in stock, at a good price, and amazingly fast shipping.
Bought it since 33mm is bit slim to the road I ride but I have a small tire clearance.
I can feel the difference.
Thanks for carrying this product, it is rare to find a 650b gravel tire.
Love this tire. Works well for (slower) rolling on gravel roads and relatively smooth single track. Also excited to try it out bikepacking (though I haven't yet).
