The perfect match for Zipp Clincher wheels
This so called "Open Tubular" (really a clincher tyre) is one of the best clincher tyres we have used. Very supple and lightweight with low rolling resistance and a 21mm width is the perfect race (or indeed training) tyre for Zipp wheels. Looks and rides great. Basically this is the Zipp version of the Vittoria Open Tubular tyre built to match Zipp wheels (dimpled tread pattern).
Also now available in 23mm width (sometime preferable for rear wheel comfort/handling)
