They add that extra stability and ” no slide” you need on ice or packed snow. It was fun to watch the cars that were out sliding to stops, trying to get going with spinning wheels etc. I was having fun riding through the deeper powder on the road side and enjoying just how nice and quiet it was with less cars and the snows muffling quiet. I also rode a bit today in the 18 degrees, but that was a little lower than my clothing was good for so I only spent a half hour or so before returning home. It’s always fun to cycle in a different type of challenge and environment, and that’s why I love riding in the snowy weather.
