I searched online for steel frame bikes and found that in the UK there is only one dealer for Simoncini frames made in Italy. Having looked at the website http://www.simoncinitelaibiciclette.com/contatti.html
you can see the design detail is with Gilco. They have some very unusual designs and also helped colnago. At one time simoncini made steel frames for colnago under licence. As the previous picture I have included the original which I intend to base on my own bike.

the site is in Italian and English
The colours red I will base on my Ducati 916 and have chrome as the other colour. Components I will try to keep Italian and campagnolo used where ever possible.
I popped in to see Edward at http://www.cyclesclements.co.uk/
He was brilliant in helping me to size up my frame on the bike and with adding components. As i sat on the bike, visually he was quick to point out my size bars needed. With a tape measure he was able to size the frame. For me the frame has to fit as when you are on the bike for a long time the last thing you need is to be uncomfortable on the bike. He helped me to choose design and components for the bike. If you visit or call Edward I am sure you will be impressed by his knowledge and skills in cycles.
