Good luck with your decision making.
Had not realized Di2 was such a good feature. Can a 105 group bike be upgraded to electronic shifting?
in any case I will have to go test ride a Bianchi at the LBS that features the brand. Like many folks around here the interest in aesthetics and technology of a bike is very high.
