I have a question that might be a bit stupid: this year I'm really decided to not give up my commuting unless there is at least 20 cm of snow on the ground (I live in Toronto). I hate having to walk to school instead of riding because of too much snow. So I was wondering what I should put on my pedals. I've used toe clips for years and I just switched to clipless this summer on my touring bike. What do you guys think is the safest, or more appropriate, for riding on snow? clipless, toe clips, or none?
