Today, near the end of my local bike trail, I had stopped, kick stand down contemplating whether to adjust the DER, or just ride home and do it there. A Jeep with a bike rack loaded on the back stopped, and the driver asked if I needed help. It was one of the owners of my LBS, Mud, Sweat, and Gears in Orange City, FL. He said he couldn't drive by one of his customers who might be having trouble. That is pretty good customer service,I'd say. One more reason I would rather not buy from the big box stores.
