This is a Mercian Professional in 853. The colour- Bianchi Blue. Perhaps a silver Campagnolo spider chainset would have been more in keeping aesthetically but I wasn't building a retro build and I like Ultegra. The seat post is Kalloy and the quill stem 3TTT; Mavic Kyserium Elite wheels. Shimano touring A600 pedals. Brooks Swallow Titanium saddle and tape; Gilles Berthoud bar end plugs. Dura-Ace headset. (Shimano have stopped making Ultegra headsets). Deda 215 Deep bars - I wish they were silver but otherwise they are nice. Thank you Ray for measuring me and the artists of Mercian who made this beautiful thing.
