I only have about 300 miles on these G One Ultrabites and so far they meet expectations. They clobber gravel, hang in the soft and hard dirt and roll fine on short asphalt blasts. They stay planted in turns and are a fair value for the price. My workout bike has grip and control now. I stick with what works for me on my 3 bikes and for the past decade Schwabï¿½s have not let me down. 40:years cycling and yes Iï¿½ve run many other brands. Hope this helps a bit.
I bought this specifically before a big event because the dry weather had loosened up the roads a bunch, and a pre-ride showed me that my regular G1's prevented me from being able to stand while climbing. With these on, I could stand on the steep stuff. I would not want this level of knobs for most gravel rides, but being able to put the teeth on when I need it is great.
Rode this on my front gravel wheel for a 66 mile adventure ride with mixed terrain; smooth and washboard gravel, loose rock and sand. Handled well and took it all on. Some road noise on pavement but good for tarmac too.
I'm running a 50mm Ultrabrite as the front tire on my Moots Routt 45 for routes with a high percentage of gravel. Haven't put it through its paces completely. But pretty cushy ride on descents in the Virginia Piedmont so far. A fair bit of friction on pavement. Definitely an off-road tire.
