Quoted message said:I've read numerous sites and articles about rolling resistance and
tires pressures, but none make any mention of effects of varying
degrees of road surface roughness.
I wonder if adhesion is also a factor. There's one place down in NJ where I
ride a multi-use route that's paved with blacktop, but where joggers have worn a
singletrack next to it.
Going from the blacktop to the singletrack is like night and day.... the two
surfaces seem equally smooth, but the bike goes faster more easily on the
singletrack.
