Koga Miyata GranTour bike review

Koga Miyata produced the GranTour bike in 2004 and can be classified as a Commuter bicycle.
GranTour bike is available in many sizes such as 50cm (centimeters), 54cm (centimeters), 57cm (centimeters), 61cm (centimeters) and 63cm (centimeters).
Koga Miyata Commuter GranTour can be found in a few colors, among these colors Light Bordeaux Red and Brown Metallic .
This bike is equiped with 700 x 37c Continental CityContact tires and Sapim stainless steel spoke wheel while the rims are manufactured by Mavic A317 Disc, 36-hole. Koga Miyata equiped this exact model with Shimano Nexave brakes, Shimano Nexus levers braking system and Front: Shimano Nexus generator, Rear: Shimano Nexus hubs.
To guarantee the comfiest ride Koga Miyata used 7005 aluminum material for the frame. ITM touring alloy high strength material is used on the handlebar of this GranTour to ensure the perfect handling while the stems are made of Zoom Satori.
For the smoothest biking experience Shimano Nexus, 33 teeth is used on this bicycle linked to KMC Z510 chain that is easily replaceable as stated by Koga Miyata, the whole system is connected to a high reliability Shimano Nexus gear shift levers.
