The third in Vittoria's family of cross racing tubulars, Cross XM is for loose terrain and muddy courses. This is the clincher version of the Evo XM tubular tyre.
|Wheel Size:||700c (622)|
150 TPI casing and MTB World Cup driven tread compound as the Cross Evo's, but with an aggressive, widely spaced tread knobs to shred mud and grip firmly in acceleration, braking and cornering, even in the most challenging Winter conditions.
Superfine casings give all Vittoria's Cross tyres their signature silky ride, light weightness for great acceleration, great puncture resistance even at low pressures, plus a competition-derived offroad tread compound.
No need for compromise now, you can run tubulars or clinchers throughout the cross season with the same outstanding performance characteristics as your summer race tyres.
Cyclo Cross tyres are for use with road wheels to allow them to be ridden off road. They range from 30 to 35mm wide and are designed with different tread patterns to suit the various conditions that can be encountered during the Cyclo Cross season. Usually at the start of the season the ground is dry and hard so a narrower low tread tyre is needed as low rolling resistance is a priority. Later in the season when the ground is wet, grip is a priority so a wider tyre with increased tread would be the better option.
Vittoria Industries Ltd. with an annual production of more than five million tires (mainly for race bikes) and nine hundred thousand famous tubulars all developed and produced in its wholly owned factory Lion Tyres in Thailand, is one of the largest race bike tire specialists and producers in the world. Its mission is to create higher value for its stakeholders and offer high quality tyres with the best available technologies to professional riders and bicycle enthusiasts. More than 15 professional teams (Pro Tour and Continental), several National Cycle Federations and the UCI Technical Centre in Aigle (CH) have used Vittoria tires for their races and training programs for many years.
|Recommended Vittoria Tyre Pressure|
For normal road surface and dry conditions. Note rim specifications regarding max tire pressures allowed. For wet or rough roads, decrease by 0.5 bar (7.5 psi). For tubular tyres, increase by 0.5 bar (7.5 psi).
Ideal tyre pressure is subject to many variables such as road surface, weather conditions, bike materials and setup, rider’s weight and lastly, riding style. The best way to fine tune ideal tyre pressures is field testing a variety of different pressures. One method is to use a short criterium style circuit, preferrable with a variety of corners.
Start with the suggested pressure and ride a lap. Each following lap, lower the pressure by 5psi until you feel the tyres start to “wallow” or move a bit. This is your lowest pressure point. Return to the above table pressures and raise 5psi each lap until the tyres start to bounce and skip/move across the surface. This is your max pressure. Decrease by 5 psi from here until you feel you have the best pressure for the conditions.
Keep a tyre pressure log, including road surface, techinicality of the course, weather conditions, tyre type, brand, and TPI. Finally, the bike you used and your weight on that day. Over time, this log will become a valuable tool for referencing tyre pressures and road conditions in order to optimize your performance when on race day.
