Rear derailleur shifting issue
I have a suntour arx rear derailleur on my nishiki mixte, and it has been having trouble for some time shifting onto the largest rear cog (32 tooth). In the best limit adjustment I can find, it will shift fine into this cog on flat ground, but under load, it will hesitate for several seconds, and then shift onto the wheel OVER the cog (thank god for my dork disk!). I did add a link to the chain in order to help with this situation, and it seemed to help a little, but the problem has not entirely been corrected. Maybe my chain is still not long enough? What do you think I should try next?
