105 or ultegra or Di2
Hi, I'm interested in a new sportive bike - I've read all the stuff on bike radar etc but they never cover my specific question. I have small hands and find that the current pattern with 105 etc make the brakes a bit "wooden". I have tried Campagnolo Veloce with its single shift blade and found that better. So is Ultegra better than 105 and is Di2 better than those given that there are no mechanical gear linkages?
