Giant Revolt 2 vs Giant Anyroad 2 drag/roll resistance I own two bikes: * Giant Revolt 2: < * Giant Anyroad 2: < Experimentally Revolt has a better roll than Anyroad. This really bugs me because: * Anyroad has a stiffer fork. * Anyroad tyre width 32, Revolt - 35. * Revolt weights slightly more. I've perfectly adjusted cones for Anyroad, experimented with tyre pressure, switched riders. The only thing I didn't change is the hubs. Revolt has _Formula [F] DC20 [R] DC22, alloy disc hub, double-sealed, Loose Ball Bearing, 32H_. Anyroad has sort of noname _Giant, [F]24h, [R]28h_. Does anyone know anything about this mysterious Giant hub? Could it be a culprit as the Formula hub gives better roll? Are there any other suggestions how to make Anyroad roll better?

Running both tires at the same PSI could be your problem. In a comment you stated you are running both at 70 PSI.

Tires of different width will typically have different design pressures. Larger tires run at lower pressure. Run both tires at the max pressure for _that_ tire. On the sidewall will be an operating pressure range for _that_ tire. Run both tires at the maximum for _that_ tire.

If you are running both tires at the same pressure you are penalizing the smaller tire that is designed to run at a higher pressure.

The size of the contact patch is PSI times weight. So if you have 140 lbs on the tire at 70 psi the contact patch is 2 square inches. The more narrow tires must have a longer contact path to achieve that same 2 square inches. The more narrow tire must deform more. That deformation is rolling resistance. More deformation is more rolling resistance.
