So, since my original post, there has been no sign of my old bike.
The bike that took me from the dizzy heights of Bealach Na Ba to the dizzy lows of the under carriage of an articulated lorry has once again disappeared.
I thought perhaps the current owner may have taken a week off work. This morning there was another bike in It's place. I'm currently of the thinking that my old bike has been replaced by a fuckin' Dahon folding bike.
Perhaps someone stole it?
