It's actually melted now. I did have my rear wheel slip going up a hill when I hit some black ice. I think I'm looking for an excuse to buy another bike. In April I bought a Giant ATX lite and put some Jones H loop bars on it. I love my new bike and don't want to ride it in the winter. That has me riding my 19 year old Schwinn Mesa. Studded tires and it would probably be OK. I've grown to dislike its grip shifters. But if I'm going to start being a full time winter commuter, I want the best tool for the job. Even If I get the studded tires, the bridge may have me walking again, if it gets bad. Also If I stick with the old Schwinn, I may have to dump some money into it.
