PRO FIT Carbon: The Stelvio series utilizes Marin?s T3, or Tube-To-Tube, carbon construction process to deliver a chassis that is stiff and responsive for riders wanting maximum performance. The light weight all-carbon frame and fork combinations feature a tapered 1.125"-1.5" head tube for precise steering control plus an ultra-stiff BB30 bottom bracket system to transfer energy from the pedals directly to the rear wheel for improved climbing and sprinting performance. Formed and arced seat stays smooth out rough sections of the road to minimize rider fatigue.
PRO FIT Alloy: The San Marino delivers the same performance features as the higher-priced Stelvio range with a more affordable aluminum platform. Top shelf components from Prologo, FSA and Vittoria adorn the triple-butted frameset to yield a race-ready bike for aspiring riders and racers.
