Already have a heap of 10 speed parts so was thinking of going 10 and saving some money. I do have some 10 speed bar end shifters if these will not work, but they are pretty old and prob worn a little.

Pretty sure the 11s shifters pull a different cable amount than the 10s, unfortunately.

No idea what that means, but I get what you mean.

Thanks mate, looks like I might have to use the old shifters.

No, like 11s ERGO and a Campag 10s rear der, it undershifts quite a bit plus the LH/front shifter is optimized for 11s CR spacing since it is positional. They shift 11s spacing as well, not 10s.
If you have 10s barends, and they seem 'worn', replace the shift springs..they use LH ERGO springs for the RH shifter and the LH shifter is friction..doesn't wear out.
