Cool, I appreciate the details. I will say I have owned and spent lots
of time on bikes with Shimano 9, Shimano 10, and Campy 10. In sheer
terms of functionality I find all these systems great and have no
strong preference for either. And while the Campy front derailleur
system is definitely better than Shimano's, I've also never experienced
any problems with trim on a properly adjusted Shimano bike. Front STI
is just very sensitive to proper adjustment, and a lot of riders and
shops don't seem to set them up accurately. Once it's dialed in it
works very well.
I'm also a big "double check I'm in the big ring while coasting down a
fast descent," so I'd have a real problem unlearning that habit. And
you mention it works better if you "take your time shifting," which
doesn't sound like a good thing in a thoroughbred racing group like
I'm excited SRAM is offering an alternative, but I'm getting the sense
that beyond the boutique appeal there may need to be refinement before
this stuff is at the level of the high-end S and C stuff.
