Continental has released the Grand Prix 5000. Lighter, faster, lower rolling resistance, increased rider comfort and greater overall grip with the same puncture protection; the GP 5000 may well set a new standard for clincher tires.
 
Improvements from GP 4000 S II:
New BlackChili compound specific to GP 5000
12% better rolling resistance
Improved grip with LazerGrip engraved texture
Lighter, enhanced liquid-crystalline polymer Vectran protection system
Active Comfort Technology elastomer layer to cushion, reduce vibrations
Truer to listed size (with some variation based on rim width, tire pressure)
10 grams lighter per size
