Continental GP 4season 700x25c

The GP 4season is the tyre of choice for cold and wet winter conditions. It has a rubber compound with Silica in it to prevent the rubber going solid in cold weather. This enhances grip when the temperature drops. Fixing a flat is never fun particularly in the winter, so the GP 4season has 2 layers of Continental's Vectran anti punture belt below the tread, and DuraSkin mesh woven into the sidewalls to prevent cuts. The 25c width is a little fatter than the more normal 23c road tire, however the 25c size gives more protection from pinch punctures, a smoother less jarring ride on rough surfaces, and better grip. Unlike other winter tyres the GP 4season is light weight, meaning it can still be used in early season sportives and races, as is evidenced by some of Continental's sponsored teams using it in some of the early season races and Spring Classics
