Hi All!, I am just getting back into biking after close to a 20 year absence and am really enjoying it. I bought a Giant OCR 2 bike and have been slowly getting used to the differences in technology the years have brought. The gears are paired with the brakes and work with a sidways motion. A black lever is used to shift up and the brake handle is pushed sideways to shift down. I am finding the gears but am having trouble organizing a picture in my mind of the gear layout. Eventually I get to the gear I want but there is no organized pattern emerging. Can anyone explain for me the gear sequencing on this bike? I could really use the help! Thanks. Bill
