Odd coincidence, I upshifted twice on Red yesterday charging up one hill standing, when I got to spin speed and wasn't in the mood to sit down or spin standing up. Flawless shifting. I've also done downshifting up hills standing, no problemo. At least for the RD. FD downshifts shifts uphill sometimes require a little soft pedaling, but it's not hard to figure out how to do this, or you can get a less-flexy steel FD cage. Overall Red's a great gruppo.
