Been riding with my son-in-law on-and-off for about a year now - so I'm pretty
sure of his comfortable cruising speed on the FS bike with WTB Mutano Raptors
@35 psi I let him use: it's right around 12 mph with no wind and no grade.
Last weekend, we did a 3-hour ride with one change: I put 1.25" slicks on the
bike an pumped them up to 90 psi.
His comfort-zone cruising speed seemed to go up to almost exactly 14 mph...maybe
even 14.3 or 14.5. I always let him set the pace - mostly following a little
behind and to one side, so there wasn't any 'pushing' involved.
On a few lunchtime rides during the week, I tried doing 10-miles for time on
each type of tire. Only got four rides in (2 each set of tires). My average
on the slicks was 17.4 mph. On the WTB's it was 15.6.
Overall that sounds to me like a 12-16% advantage on a paved surface for slicks
at 90 psi vs high-volume MTB tires at 35 psi.
Do those numbers hold up in anybody else's experience?
