So I'm moving to Halifax for school in the fall and I can realistically only keep one bike with me. During the last few winters I've been riding a cheap rigid MTB single speed geared fairly low with fat studded tires. I notice that people recommend fixed during the winter even with narrow slicks. Does this really work well or is this just hardcore posturing? Can you ride in all conditions? How low do you gear? I can see how a high-pressure slick might cut through drifts better. It would be nice to just bring my cyclocross bike with a fixed/ free wheel. Thanks.
