Also, maybe y'all can provide some insight for me....I have an old Raleigh bike that has 27inch wheels on it and I was thinking that if I put some 700c wheels on it and some CX tires, I could have a ghetto CX bike for commuting this winter. Does that sound nuts? It has these old Weinmann centre-pull brakes on it and I think that they will provide some pretty good clearance for knobbies, especially if I go with 700c wheels.

The thing is a beast but I think that once I get these steel 27inch wheels off of it, it might provide a pretty decent ride.
