Campy girl here....
I love my chorus groupo!
I remember when I was having my bike built making the decision between Shimano or Campy. I did my homework and to be honest the quality of either seemed to me to be the same only Campy was a bit higher priced.
I asked a trusted cycling friend what he thought about the difference between the two and his reply was:
"Campy is just breaking in when Shimano is wearing out."
That pretty much settled the debate for me as well as some advise from the guy who built my bike and owned the bike shop. He said that when a part say a little spring or something breaks on Shimano you have to replace the whole part, whereas with Campy you can buy and replace just the spring. So in the long run with one break down you can re-coup your cost by buying Campy.
Oh and for us girls the extra plus is in the size.......the shifters and levers are smaller and a better fit for our hands compared to the size of Shimano shifters and levers.
Now I've used both Shimano Ultegra and my own Campy Chorus and no noticeable difference in performance of either for me it all boiled down to what one would be less repair and less expensive upkeep. Campy won hands down.
Whatever you decide I'm sure you'll be happy with it, just enjoy the ride!
