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 between the other bikes and the Matthews, starting with Q and including wheel weight and diameter, overall bike weight, and tire width, that it's really a guess to say this, but just perhaps it is easier to push a given gear in given conditions at low to moderate cadences with the longer cranks -- I seem find myself pushing a 68 to 72" gear on the Matthews, on pavement, surprisingly easily given the weight of the wheels and the bike compared to the others -- but again, it's just a guess. But it's a guess that will have me staying with 175s for off road.
I've never used 165s. > On Saturday, February 3, 2018 at 3:33:36 PM UTC-6, Deacon Patrick wrote: >> >> Both my Hunqapillar and Quickbeam have 175mm crank arms.
