I'm a new biker in Washington, DC. I'd like to continue biking during the winter, even when there is snow and ice outside. We don't get much here in DC, but sometimes there is enough to make conditions slippy and icy, especially on bike trails. I have seen that there are special bike tires for riding on snow/ice, as well as attachable chains (but that can only be put on when the tires are a bit deflated). I used to run and in icy conditions I would use these stretchy, crampon-like things. They're made of rubber and fit over the soles of your shoes. They have metal rings hooked onto the rubber at the bottom, giving traction on icey surfaces. Is there a similar thing for bike tires? Since conditions here are so variable, I would like something that I can take on and off easily (without deflating tires). Any ideas?
Also, if any DC area bikers have experience with winter riding, any advice would be much appreciated.
