yah, yah, yah, don't cross chain - I say, then why is it there? I want to get down the street as fast as possible not do calculations in my head, I don't even want to look down. What chain am I on, how many teeth, let's see, if I shift now, what ratio will I be in? will I have to up or downshift from there?, etc. etc. easier to just stay in that ring and make the quicker shifts.
I finished a 30 miler this morning... annoying to have it rub, nobody else on my group ride seems to have this iisue, Bianchi, Felt, Scott. Switching from the small to big ring is not clean and quick on the Rival either. Just not a big fan of it, debated getting the 105 group... woulda, shoulda, coulda.
