The Hakkapelita W240 is a great all around winter commuting tire! At 40mm wide and featuring 240 carbide studs, it will maintain excellent traction through icy and snowy conditions. Center studs grip glare and black ice with ease. The knob profile and corner studs help you navigate through icy ruts caused by tire and foot traffic. Overall its a fast tire by winter standards, but offers more grip than just about any other 700c tire on the market.
