More about type of tire than brand. I've had about 10 'gravel' bikes (from touring, cx, gravel, drop-bar mtb...i.e., bikes I ride on non-paved surfaces, in addition to paved). I use to focus on bikes that can go fast on road, and be okay on gravel. After having a drop-bar mtb with 2.2 I would say that's now my favourite. I don't race or participate in events. This bike and its tires can go everywhere I want to go, so I have no restrictions. Today it was wet so I went out for the first road-only ride with this bike (the previous road bike with 25mm tires stayed indoors lol). On my normal route I was 1-2km/hr slower, and more comfortable when I returned home (pot holes, broken pavement, spilled sand/gravel on the road...didn't think twice as I rolled over it). So this is the only tire I need (it happens to be the Sparwood, but anything with a good centre tread for road and some treads down the sides for covering on gravel, is what I'm happy with).
