The handlebars may be too wide. If you aren't wide shouldered you may want narrower bars. Two cm. smaller from the stock bars on my current bike made a world of difference to me in terms of comfort and confidence. If you have a bike that fits you well (and it's an efficient fit - not just something you've put up with and gotten used to over the years) try to duplicate it as much as you can - especially if you have a dealer that wants to work with you. Don't forget to consider crank length.

Is that a compact crankset? I bought mine not knowing what I was buying and fell in love with it. Beats a triple IMO.

Get used to the brifters and you'll wonder why you didn't get them a while ago.
