I think I remember seeing them out & about many moons ago. It looks retro-tastic! good work there, especially liking the Flexstem and the colour choice for the cable outer Those WTB tyres are ok for the money too, I run them on my Raleigh.
I was thinking about the chainset another XT but older , will have to keep my eyes peeled and also the seatpost has been stripped and polished the camera pics dont really show it .
