For years cyclocross World Champion, if you are a professional rider or you just like to ride hard under extreme conditions, the Grifo is the tire you need. Unbelievable grip and no compromise at all on rolling resistance.
The silk casing is much finer and stronger than cotton or polyester and it also makes the ride softer and smoother. Thus higher cornering speeds are possible on technical trails. It features a Puncture Protection Strip (PPS), which is an extra layer of highly resistant material between the casing and the tire to reduce the risk of punctures.
