I have a 1988 Schwinn Traveler that I commute on. It has 27 inch wheels and I'm running 27x1 1/4 inch tires. I fit SKS 35 mm fenders on with some difficulty. The fender just barely clears the tire in front. Even with creative modifications to the fender, I am just out of frame clearance.
Now winter is almost here and I think I need a more aggressive tread on the tire to deal with mud and snow. The problem is the only 27 inch cross tires I have found are 1 3/8 inches. I am certain a larger tire will not clear the fenders.
What are my options here? Is there a tire that might work for me? Should I consider switching to 700c wheels? Is it realistic to think my SKS fenders will actually clear a 700x35 tire?
