As I am getting back into the cycling thing, I pulled out a Trek 820 I had sitting behind the shed for about 2 years. It is going to need one 26x1.75 tire, the front one I replaced and is relatively new, seat, chain, and the grips are shot. Also the cables are going to need some lubrication.
I bought this Trek at a yard sale for $40 about 5 years ago and the guy gave me a trainer and slick tire with it so I can ride indoors in the winter. I never used the trainer. One day I was cleaning out the shed, moved it around back with a couple other bikes and forgot about them. I have a BMW road bike and my wife has a Magna mountain bike that are like new and those are the bikes we ride all the time. She doesn't want me to beat on her bike (Magna) by using it on trails.
My question is should I try to fix the Trek back up or should I give it to some kid who can tinker and buy another used bike in better condition. I hate to waste stuff and it was a good bike before I forgot about it. I figured I can spend about $50 in parts and put it together myself.
Attached is a picture.
