Does anybody know if you can set a Campy 10-sp Record bar-end rear shifter to friction mode? Or is it indexed only?
Thanks,
indexed only.
thx…
shimano 7800 have indexed and friction
campag have indexed and have a cable tension adjuster to allow on the fly cable tension adjustment
sram have only indexed
shimano 7900 have only indexed

Shimano sucks, that is just stupid. Why would they do that? They are SO SO far behind the times 
Observations from my personal experience that you might find helpful:
Shimano 7800 bar-ends in friction mode work with Campy rear derailleurs - the cable pull is the same.
Shimano 7800 bar-ends in friction mode will NOT work with Sram rear derailleurs - the cable pull is different.

Huh…in friction mode I have used a Suntour Superbe Pro shifter with about everything in the past decade. Friction mode will work with ANY spacing.

The only thing I can think of is if the total cable pull required by the mech exceeds the capacity of the lever - that could potentially cause an issue.
which is doubtful b/c then what would the use of limiters on the rear der?
I think the OP likely meant indexed mode.
As far as i know it won’t work with SRAM because of the 2:1 ratio, whereas shimano uses something much closer to 1:1

This is exactly what I’m talking about - 7800 bar ends, in friction mode, effectively limit a Sram rear derailleur to nine speed - you can’t get to that 10th cog (usually the biggest, or the smallest depending on how you fiddle with it) because the lever can’t rotate enough to handle the extra cable travel required.
It’s not a spacing issue, it’s a cable travel issue. I’d be willing to bet you’d run into trouble with your Supurbe bar-end and a Sram RD.
This actually brings up an opinion I have that everyone seems to think is crazy - I think it’s much better to use friction bar-end levers on a TT bike. I have a bad habit of knocking the barrel adjuster on the rear derailleur when I’m futzing around on race days - thereby knocking off the alignment just enough to give me a little chain noise while I’m racing if I’m going indexed. I find it much more convenient to be able to make an adjustment on the fly - with modern drivetrains, shifting is still nice and quick/precise and it gives me something to do with my hands when I start getting bored. I’ll never do without indexed shifting in mass-start racing (it was huge when I got my first Dura Ace SIS bike way back in the day) but I think for TTs indexed shifting is over-engineered, feature bloat, useless complexity, superfluous, etc.
