I was surprised to hear any criticism of half step gearing set ups. When
they are not perfectly set up they can be a pain, for sure. Once they are
tuned in, though, they are the very pinnacle of friction shifting in my
experience. I have had better luck with Shimano Deore than Campagnolo on
these, but the old Deore on my Mooney shifts so precisely and crisply that
one might mistake it for indexing. I seldom need to trim more than a couple
of times on a 30 or 40 mile ride. Friction shifting doesn't get much better
than this, folks.
