Giant OCR 3 bike review

Giant produced the OCR 3 bike in 2005 and can be classified as a Road bicycle.
OCR 3 bike is available in many sizes such as Xsmall , small , medium , large and xlarge .
Giant Road OCR 3 can be found in a few colors, among these colors Corsa Red and Cloud Blue .
This bike is equiped with 700 x 25c Michelin Dynamic tires and Stainless steel spoke wheel while the rims are manufactured by Alex DA-22, 32-hole. Giant equiped this exact model with Tektro dual pivot brakes, Shimano Sora 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 3 to ensure the perfect handling while the stems are made of Giant Adjustable alloy.
For the smoothest biking experience TruVativ Touro, 30/42/52 teeth is used on this bicycle linked to KMC Z72 chain that is easily replaceable as stated by Giant, the whole system is connected to a high reliability Shimano Sora STI Dual Control gear shift levers.
