I've been commuting to work now for almost three months, mostly along the Hudson River bike path. I intend to keep it going through the winter, but I'm a bit confused as to what changes in gear I should make. I have a handle on clothing changes; my job entails working outdoors about 50% of the time so I have long since learned the value of layering and having the proper gear. My questions are more about changes to my bike. I have seen it mentioned that many people prefer to have a separate beater for winter given the harsher environment, but having two bikes is not an option for me for both financial and lack of storage space reasons. So my question is about what changes I should make to my commuter (7500fx) to winterize it.
This will be my first winter cycling regularly. What are the conditions on the Hudson bike path like in winter? Does it get plowed regularly? What would people say is the best tire for urban winter?
