I'm pleased to see so many drop bar winter bikes. Now I don't feel like so much of a oddball.
Last year was the first winter season I attempted to use a drop bar bike. The bike's limited tire clearance barely accommodated a Marathon Winter on the front. A Nokian W106 (which I like better) wouldn't fit. In the end I wasn't happy with it but I did enjoy having a drop bar.
So for this year I've got an old 700c mountain bike that I plan to put Salsa Bell Laps on. They're drop bars designed for cyclocross. They flare out a bit in the drops and I plan on getting a size thats wider across the tops than the bar that I had on last year's winter bike.
