1:20 total time with 2392 feet of climbing. I have been a Shimano guy all my life and I am now thrust in to the world of Italian componentry.Campy Chorus 10. I don't have a Campy rear wheel so I am running a rear Shimano wheel with a 9 speed Shimano cassette (close to Campy 10 spacing) and dura-ace chain with the rear derailleur limit screws adjusted to just 9 shifts. Works close to flawless. If I can dig up an 8 speed then the spacing is the same as Campy 10. Everyone knows that!
