Yes, I just called my shop, and you'll still have lateral chain wear from the extreme angle. But, maybe since you're not hitting the side of the derailleurs, you're not getting that additional wear and tear? I didn't get to ask him that. In any case, it's really precise, and can handle the shift from small to large chain ring in any gear without any effort. I think even when climbing, you don't have to ease up on your pedal when front shifting. I read that in this review:

I'll keep my old Ultegra until it dies, and probably get the same level components next time. But, I can see the appeal. If you're a (rich) tech geek, you're going to love this. I'm neither, but it was fun to try!
