Completely problem-free, super low-maintenance until this issue.. but quite suddenly, the chain gets stuck between the big and small rings when I drop from the big to the small. Went from no problems to it happening pretty much every single time I shift rings... I have to make sure I'm easing up and be prepared to immediately backpedal so it'll un-stick itself and fully drop to the small ring. No issues going back up to big ring.
Rings and chain are cleaned and lubed every ride, thoroughly so every few rides. The chain does have about 2,000 miles of gritty PNW all-weather riding on it, but, as I said, I do clean and lube very regularly, and it still gages good with a Park gage.
My thoughts are: clean/lube/re-tension the front mech cable and re-set limits... but that's all I got.
Thoughts?
Thanks!

Chain 'dancing' most often a front der adjust issue. Make sure the Fder outer cage is aligned with the chain when in highest gear, big ring and smallest(highest) gear. That turns the tip of the front der, where off the big ring stuff happens, inward a wee bit, making sure the shift is aggressive enough to get the chain to the small ring.
Tight cable also, and inner limit screw so when in lowest gear(small ring, biggest, lowest cog), the distance from the chain to the inner cage is 'about 1mm. No more or else you may get chain to front der rub when in highest gear.
Front ders can be kinda a black art sometimes.
Not chain suck, BTW-that's a different issue when the chain doesn't come completely off the big ring, gets grabbed by the small partially and gets crammed between the chainrings and the frame.
