I was exhausted by the time I got to the lake. We've had about 4 inches of snow in the last 24hrs. I think that screws coming out of the tires add massive rolling resistance. It's brutal to ride this thing around town. Traction is superb though. Once on the ice, I was more than impressed. I crashed a few times, but never due to lack of traction. Just due to riding too fast into a snow bank, somehow thinking that I would casually roll up and over it. It was good.
