Hello all. Today on a beautiful day, decided to take my bike out to get a little exercise. Noticed that when I went to shift gears, nothing happens and my pedal is free spinning. I think I might need new shifters. The bike is an older Marin kentfield hybrid I believe. Bought it off someone on Craigslist a few years ago. have only ridden it a few times around the block. It sits outdoors all the time. will be getting a bike shelter for it. Unfortunately since I just registered, can't post any pictures until I've posted a few times according to the forum guide lines. Thanks
