I've had my Rambler about three years and enjoy riding it. However, this spring the back wheel has been flat more than it's been inflated. It seems that every time in inflate it, it's deflated by the next morning. When I remove the tube, it has a small hole, usually in the same place. It appears that one of the spots where the spokes enter the wheel is sharp and is puncturing my tire. I've placed duct tape over it, but it still goes flat. It's getting more than a little frustrating.
What else should I try? Or is this a bike shop issue?
