Built for extra grip in wet weather, Challenge's Forte Clincher has an aggressive tread pattern. It's hand made on their supple 300tpi SuperPoly casing with a durable tread compound and tough polyester in the sidewalls. The center tread rolls quickly while the lateral side tread sticks to the road in the corners. And, there's flat protection under the tread.
This is a folding clincher tire.
