The new Champion System MAC points leader jersey, design by Sommerville Sports

With just one month remaining until officially kicking off the 2010/2011 international cyclocross season in Pennsylvania on September 11th, the Mid-Atlantic Championship Cyclocross Series (better known as MAC) has announced a new title sponsorship with Champion System Sportswear, a leader in custom technical custom apparel. The 11-race series, which stretches from the tip of New York’s Long Island to the southern city of Baltimore, 450 kilometers away, will now be known as the “Champion System MAC Series”. “We’re excited to be the title sponsor of the MAC series” said Charlie Issendorf , VP of Sales at Champion System. “Supporting cyclocross teams and events is a big part of who we are at Champion System, and we wish the best of luck to all the racers competing in the series.”

As part of its agreement with the series, Champion Systems will be providing points leader jerseys in eight categories for at least the next two years. Champion will also provide series champion apparel not only for 2010 and 2011 series champions, but also for defending champs from the 2009 season.

Champion Systems joins Carrier Class and Revolution Wheelworks as new sponsors for the 2010 season. Revolution Wheelworks is a name familiar to many ’cross fans as one of the sponsors of Valentin Scherz, who will be defending his Champion System MAC title with the help of his new Philadelphia Cyclocross School team. Probably less familiar, though more ubiquitous within the lives of bike racers and their families, is the CarrierClass Group, a world class provider of wireless communication and green energy infrastructure. Also sponsoring the 2010 season are long-time MAC sponsors and Hammer Nutrition.

The Champions Systems MAC Series kicks off with the first UCI-sanctioned ’cross race in the world for the 2010-2011 international season with the Nittany Cross around the world-famous “T-town” Velodrome at Pennsylvania’s Valley Preferred Cycling Center. The eleven-race series visits five states and includes nine UCI-sanctioned races. This year, Charm City and Granogue, traditionally the most highly attended races on the schedule, have both expanded to two-day formats. Last year’s Elite Champions, Switzerland’s Valentin Scherz and American Laura van Gilder both intend to defend their Champion System MAC Championships, with Scherz bringing some additional firepower in the form of yet another Swiss rider, Anthony Grand.
