OCR 1 bike is available in many sizes such as Xsmall , small , medium , large and xlarge .
Giant Road OCR 1 can be found in a few colors, among these colors Racing Blue and Silver Lining .
This bike is equiped with 700 x 25c Michelin Dynamic tires and Stainless steel spoke wheel while the rims are manufactured by Xero XSR-3, 20-hole/24-hole. Giant equiped this exact model with Dual pivot long-reach brakes, Shimano Ultegra STI Dual Control levers braking system and Aluminum, Q/R hubs.
To guarantee the comfiest ride Giant used ALUXX aluminum material for the frame. Anatomic drop bar high strength material is used on the handlebar of this OCR 1 to ensure the perfect handling while the stems are made of Easton EA50.
For the smoothest biking experience TruVativ Elita, 30/42/52 teeth is used on this bicycle linked to 1/2 x 3/32" chain that is easily replaceable as stated by Giant, the whole system is connected to a high reliability Shimano Ultegra STI Dual Control gear shift levers.
