Two of our favorite words: Grand Prix.
The Continental GP 4-Season Tire takes the overall grippiness and performance inherent to the G.P. 4000 and adds extra sidewall durability to increase the punture protection. DuraSkin is Continental's patented nylon mesh layer that significantly beefs up the sidewall for flat resistance without compromising a supple ride quality or adding significant weight.
Continental offers the GP 4-Season Tire in three sizes -- 700x23, 700x25, and 700x28mm. It has a Grey tread with Duraskin sidewalls.
- Double layer Vectran with DuraSkin sidewalls
- 330TPI inflatable to 120 PSI, (28mm to 115 PSI)
