The Norcross EX is the carbon-fiber step-brother to the SP. The T700 carbon fiber construction is surely the first big difference to jump out between the two, but look a little closer and you will see the other differences that really play a big part in performance. The EX was given American Classic Victory 30 wheels wrapped in Hutchinson Piranha tires, and the deeper rim helps this bad boy track straight. For better stopping power the brakes used are Avid Shorty 6 cantis, and Blue stuck with SRAM Apex for the build as it is proving itself time and time again. XS SM MD ML LG XL (A) Eff.
