I have an excellent video of a (IIRC) Channel 4 proggy called 'Champions' charting the rise and fall of Boardman and Obree together, just after Boardmans Barca gold in 1992. First shot of Obree shows him on a turbo trainer in his back yard in Falkirk riding a rust-covered small-wheel chopper whilst Boardman is on top kit. Also shows Obree making up 'Old Faithful' at his mate's bike shop.
