This bike is equiped with 700 x 23c Continental Grand Prix tires and Sapim stainless steel spoke wheel while the rims are manufactured by Mach1 RJ350, 36-hole. Koga Miyata equiped this exact model with Shimano Tiagra Dual Pivot brakes, Shimano Tiagra STI Dual Control levers braking system and Shimano Tiagra hubs.
To guarantee the comfiest ride Koga Miyata used 7005 aluminum material for the frame. ITM Super Italian Pro 330 high strength material is used on the handlebar of this Gran Racer to ensure the perfect handling while the stems are made of ITM Forged Lite Luxe.
For the smoothest biking experience Shimano Tiagra, 30/42/52 teeth is used on this bicycle linked to Shimano CN-HG73 chain that is easily replaceable as stated by Koga Miyata, the whole system is connected to a high reliability Shimano Tiagra STI Dual Control gear shift levers.
