To be precise: the 175s feel harder to spin at higher cadences; for me,
that;s 90+. They feel easier to spin, or to get up to a certain cadence,
*maybe,* at lower cadences, and given the bulk and diameter and contact
patch of the wheels -- 61 mm actual -- compared to the ~ 27 to 31 mm but
far small
I like to think I can get torque slightly more easily with the 175s on my
Matthews, but really, what I feel is that they are slightly harder to spin
compared to the 170s I use on everything else. I certainly couldn't tell a
difference when I briefly used 172.5s on a Ram. There are so many variables
