The bike is an Orange Aluminium O.
I thought the forks might be Pace RC30s.
The kit on it seemed to be later 90s XT.
The paint is weathered but also there has been rubbing/scratching along most of the top tube from the bike lock, down to the bare metal. The saddle is also ripped and the padding hanging out.
SPDs looked very clean, either new or not used with cleated shoes (ie not scratched by the cleats).
I will try and get some more pics if I see it again, was may not be soon as it was the last day of the term. Also it was the first time I had seen it after a term of cycling to uni, which makes me think it is not used much as I would have seen it before.
