I just mounted a pair of these the other night. I only test rode them in my parking garage, so I can't say how they are on snow/ice yet. I've never ridden studs before, so they felt weird at first. I was afraid they'd slide out from under me on the smooth concrete. However, I couldn't get either tire to slide at all, despite trying to. I'll report back after I try them on snow (which is forecast for tomorrow). For only $31.15 a tire (from
www.universalcycles.com using a price match), they seem like a good deal.
