Wet weather and chilly temperatures can be daunting, making tire performance even more critical for rider safety. Light treading is just the start for a good grip during rainy rides and commutes. A supple and very puncture resistant tire casing made from Vectran helps hold the road better than common nylon. What's Vectran? It's the same stuff NASA uses to make the airbags used in the Mars lander missions; very lightweight and tough stuff! Even the sidewalls are made with DuraSkin polyamide to deflect debris and prevent sidewall cuts. A folding bead made of Kevlar helps keep overall weight low. Tire lifespan is high, making this an excellent choice for high-milage training and commuting.
