Some years ago my Son in Law got a new Trek MTB which he proceeded to ride into the ground. In a good ten years he never cleaned it and maintenance was the very minimum. Eventually it ended up in the shed where it has sat for several years. We have poached the wheels off it for a Giant MTB I gave him. I am going to ring my daughter tonight and see if she can work her magic on him, you know, flutter her eyelids and be nice to him, then try and persuade him to let me take it to do it up and use. Last time I tried, about a year ago, he wouldn't part with it, but I know it hasn't moved since then. Under the dirt and grot it's still not a bad bike, not that I will tell him that though lol. Needs a total strip down and rebuild but that's what I enjoy with bikes. So I will see how I get on.
