Our daVinci came with Campy Chorus 10-speed shifters, Campy FD (Mirage I believe, probably the only one that'd support quad rings), SRAM X-9 long-cage RD, with the DV custom "pulley" to convert the action, and SRAM 9-speed cassette. Rear shifting has been quite good, as long as I stay up on chain lube (100 miles is my max range between lubes). Front has been sub-par, in my (high standards) opinion - lately ring2->ring1 is almost always a no-go, but ring3->ring2 often becomes ring3->ring1->ring3->ring2, and we've done ring3->ring"5" twice now. Thankfully the DV drivetrain means throwing the chain to the right isn't painful, just greasy. For the record, I came from a Shimano Dura-Ace double, so maybe my standards are high?
