Sixty Fiver says he feels more in control on a fixie when the conditions are slick. My geared bike needs repair, so I've been riding my fixie upon his advice. And yes, it seems good. Before recently, I hadn't cycled in winter conditions in a long time, so I'm relearning it all.

Another advantage of riding fixed is that it's warmer, since you have to work harder, and even when you're not cranking hard, you always have to crank.

My fixie has very narrow tires, and they're probably not ideal, but my streets aren't slippery right now. There are small patches of ice and slush, but not many.

When I'm going over a slick part, I take one foot out of the toe clip, in case I have to put it down quickly.
