Vektran and Black Chili? Sounds like some kind of explosive...but the only thing blowing up will be your riding performance. Continental's Grand Prix 4000S II not only sport Vektran technology to increase puncture protection, but they feature Black Chili carbon particles that reduce rolling resistance, maintain traction, and reduce wear. Plus, colored sidewalls look totally fly and will give the peeps in the pack something to remember when you drop them.
