Thanks TandemGeek. Some very thorough questions.
1. Can you fill in the blanks on the list of the components you're using:
Campy Record 10 Ergo Levers2. Can you post some close-up photos of: I will try and do that when I get home tonight
Campy Record Triple Front Derailleur
Campy Record (Long/Med/Short) Rear Derailleur
Campy Record Ti and Campy Centaur Cassettes, 12x25
daVinci Cranks with FSA 53 /39 /30 Chainrings
A. The cable routing between the bars and downtube cable stops3. Can you be more specific about the shift degradation you are experiencing?
B. The cable routing at the rear derailleur
C. The rear drive train in the big-big combination
D. The rear drop-out/derailleur alignment from behind
E. The front derailleur with chain in the big ring from the side
F. The front derailleur with chain in the big ring from above
G. The cable routing / guides at the front eccentric shell
A. Does the shifting become finicky all the time (aka, just riding along) or is it in specific circumstances such as when climbing under heavy pedal loads? Appears on flats, rolling and climbing. Both the shop (I trust my mechanic implicitly) and I have adjusted things. Generally it will work fine for a ride or two, then it quickly goes down hill.I am probably being overly sensitive to the issue, but I know how Campy can perform and this isn't quite it.
B. Is it the front derailleur performance that's sluggish and, if so, between which shifts. It is the front. Sometimes it won't drop from the middle to the small. Sometimes won't go from the middle to the large. And then sometimes I am trying to go large to middle and find myself in the small with no issue at all. Also, sometimes the behavior is dependent on the gear I am in, sometimes not.
C. Is it the rear shifting that goes off and, if so, is it specific to any chainring combination? As far as the rear goes, other than dealing with the initial cable stretch, all seems pretty good back there. Occasional hiccup when it doesn't quite hit things dead on, but generally rights itself after a shift or two.
D. How fast does it degrade: 20 miles, 100 miles, 1000 miles? 40 to 75 miles. That's a guess. I am generally thinking in terms of the number if rides.
E. Other details???? We also tried moving the spindle (steel Phil Wood, 118 length) for the BB slightly off center (to the drive side) to see if that would do anything since centered wasn't working well. That hasn't helped either.
