I had a OneUp V2 before I replaced it with a Reverb AXS, and I found I had to lube the stanchion way more than you'd think, or I'd get shitty and sometimes incomplete return travel.
I know they're retardedly priced but honestly the Reverb AXS is the nicest dropper on the market, by far, not even including the wirelessness.
I don't know if the AXS uses the same design as the old ones, but the hydraulic action sucks in any weather below 60°. I would say it becomes unusable around 45°.
Also it is hand down the ugliest dropper out there with its big ol battery pack
And they cost as much as a fork/XT groupset/wheelset/etc.
