i don't recall have any issues with reaching the largest cog and i didn't center the derailleur on the cassette. and, it was on a 135mm spaced hub. that was four years ago, though. i've blinked a few times since
i have a different frame and set up, now, i plan to run the shimergo on, again. so, if i do have that issue, i'll keep your suggestions in mind. thanks!
