I'm not sure if anyone has looked into this before, but I wonder if 10sp levers would work with 11sp rear derailleur on 10sp cassettes.
My thinking is that unless the effective cable pull ratios on the rear derailleur vary between 10sp and 11sp, it should not matter which levers I am using. Am I way off the mark on this?
Why am I puzzling over this silly question? I like the look and weighs of the 11 sp, especially with the Super Record Ti option, just cannot fall in love with the 11sp levers and the complexity. Plus all of my other wheels are 10 sp. I'd just get the 11sp group and use it with an existing 10sp levers if that would do.
Appreciate any thoughts (and real test results).
There have been changes in pull ratio.
How many drivers does a buggy have?
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.
2000 Serotta Atlanta (60) '01 Records = 20.9 lbs
2009 Cannondale Caad9 (60) '06 Record/Chorus = 17.4 lbs
2009 Trek Madone 5.5 (60) '07 Record = 14.8 lbs
2011 Strong Extralite [steel] (59) '08 Record = TBD

That's my plan. I want to get the 11sp group, but use the 10sp levers and 10sp cassettes. I've always loved the campy feel and size, and think the 11sp is too Shimanoesque...
11 speed fd and rd works perfect with a set of 10 v QS shifters (as long as you use a 10v cogset, 11 speed will work with a customized index ring).
The front derailleur is not an issue.
The rear I spent some time ensuring;
1. cable route has minimum friction, gentle bends in housing.
2. coorect alignment of derailleur and hanger. frame is not new and ive had one fall!
3. limit stop adjustment. Park Tools website has a good guide for setting limit screws.
4. lastly good quality cables and set tension by the campag manual.
I would go so far to say the 2011 11sp rear derailleur works better than my 2007 10sp one!
On the otherhand, I'll add from my own perspective....the shifting with 10s levers and cog with 11s rear der goes very, very well. I have run this combo myself for the past 2 years and feel the shifting in the rear is slightly better than what I got with my near new 10 sp rear der.
The opposite combination, a 10 speed RD with 11 speed shifters and cassette suffers from a small amount of undershifting. I found an easy way to correct that problem.
