Ideal for rough pavement or smooth dirt.
- Familiarity: I've put it through the wringer
I ride a mix of dirt and paved roads. Most of the pavement is poor, and most of the dirt is very good. Later in the summer, as the dirt roads bake out, more rocks get exposed, and I switch to 40mm tires for the rougher stuff. But most of the year, they are smooth enough that a ~30mm tire at 55-65 psi feels very smooth and fast.
Fast road tires like the Pro One feel incredible on these roads, but they do have some sharp rocks, and sidewalls open up from cuts and pinch flats every once in a while. So far, the G-One seems to be sufficiently tougher than the Pro One that it holds up to these roads, with minimal speed penalty. It's a stiffer tire and requires a few psi less pressure to get the same compliant feel as a Pro One 28 (which is the same size, exactly, 30 to 31mm on an 18mm internal rim). But, speed feels excellent, and I can't tell the difference in times on various segments. I would not hesitate to use these in a "B-priority" road race.
