The Norcross SL is the high-end cyclocross racer from Blue Competition Cycles. The SL features a full SRAM Force or Shimano Ultegra group for crisp, reliable shifting, TRP Euro-X canti brakes for superior stopping power, and an American Classic Hurricane Hurricane wheelset sure to get you to the finish line before the chasers. The SL also uses a slightly lower head tube for racier geometry than the other Norcrosses, an included roller for the use of bottom pull front derailleurs, and has a new chainstay for more mud clearance.
