Winter Riding Tip...
Okay. So if you are an all-weather cyclist you likely already know this. I do have a tendency to state the obvious (or at least the known), and for that I apologize in advance. But I read somewhere years ago, and it's something that I found out really works, is that if you lower the pressure on your tires (ever so slightly) you will get better traction in the snow. The theory behind this is that more tire will be touching the ground (or snow). You don't want to deflate them so much that it is difficult to ride or dangerous...just a bit that it's barely noticeable (air, I've also read, naturally compresses when it's cold, thus the tires lose a little pressure on their own when the temps drop). Anyhow, I just thought I'd pass this on. I'd also be interested in hearing if other winter cyclists have tried this or have other tips.
I have done that, works for cars that are stuck too.
