I decided to take my 1984 Schwinn Voyageur out for a winter ride recently, which is the first time I had done that in snow and ice. I have 1 1/4" Gatorskin tires on it and SKS fenders with front homebrew rubber mudflap. Not an ideal setup for winter riding but not horrible. I had a blast riding but after 10 miles or so I had so much sand and grit under the fenders and all over the brake pads that I can't imagine that the wheels or drivetrain would hold up very long riding regularly like that. So I'm thinking about getting a more appropriate dedicated snow and ice bike--one that I consider expendable. Something like an old gaspipe Schwinn Varsity or something along those lines. I've got several other vintage bikes, but nothing that I'd really like to trash. Am I approaching this the wrong way? Is there a way to ride on snow and ice with sand and salt in such a way that bikes last a long time?
