8sp Ultegra barends --> 7sp XT der & cassette?

It's roughly the same, works nicely here.

Thanks for any thoughts.

It is nearly the same, but off by 0.1 mm per cog. You could probably put in 8sp
spacers and then it would be perfect. I believe the built-in-spacer small cogs
are identical between 7 & 8sp, but I'm not absolutely sure. Anyway, there is
only two of them so an accumulated error is not important, plus the outer cog
(small) is controlled more by the r-der H-stop when it comes to indexing.
