I love the availability of Shimano parts but i will alway be a Campy guy. My Specialized Allez came with Chorus groupset and a Record rear derailler. I got hooked after riding a double century a few years back. Ergopower controls is better than the flightdeck setup i had on my Trek IMO.
Some day before i get old i want a full Record grouppo on maybe a Merlin or Moots, possibly a Colnago masterlight.
