This bike is equiped with 700 x 23c Kenda Koncept tires and Formula spoke wheel while the rims are manufactured by Formula Xero Lite XR4, 20-hole/24-hole. Marin equiped this exact model with Shimano Sora Dual Pivot brakes, Shimano Sora STI Dual Control levers braking system and Formula Xero Lite XR4 hubs.
To guarantee the comfiest ride Marin used Columbus Thron material for the frame. Cinelli Altera high strength material is used on the handlebar of this Portofino to ensure the perfect handling while the stems are made of 3T Mutant.
