Exactly what I want. Having come back to cycling via mountain biking, I definitely want hydraulic brakes. I'd like it with a large Reynolds 753 frame, high performance tubeless tyres/rim combination, matched to high end 1980s Campag group set & hubs, Cinelli stem and bars and topped off with my old Brooks Pro saddle.
I have no idea if an old 753 frame could be modified by a frame builder to accommodate the above. I'm probably the only cyclist on the planet who would want such a creation!
That is quite a "unique" blend there :-)
