My initial impressions were of a laterally stiff wheel with high spoke tension and so the forward drive under prodding was exceptional. They really scoot. I also felt that they were a firm riding wheel and I think that is accurate, but they are not harsh.
So far the wheels have felt snappy and solid. From coast to drive, these wheels show a rapid engagement, so if that is important to you, that is good. I have noticed a bit more ‘pop’ forward over the wheels I typically run, a set of FSA MTB wheels from a few years ago.
