Maybe you stop riding a bike just because it's winter, but that doesn't mean everybody does. Some people are actually hardcore, and these tools can help you join their wintery—and deeply masochistic—ranks.

Preparing for a bike ride in the winter is a lot like preparing for a ski trip for much of the country, but if you live in a milder climate—ahem, San Francisco—you might dial back your preparations for snow into preparations for rain. Just remember: the point is that you shouldn't let the weather slow you down.
