After many months of trawling the Internet for prices for my Colnago C59 with Di2, I finally decided that Sigma Sport were the right people to purchase the bike from. Communication throughout the build was first class as was the service. If you live close enough to Kingston and want a bike shop you can trust and rely on, you must visit Sigma sport. A special thanks to Elliot for all the help he gave during the bike build.
