Christopher M.wrote a review of RockShox Reverb Dropper 1x Remote on July 25, 2017
Familiarity: I've used it once or twice and have initial impressions
Just like the rest of the reviews on here, this upgrade is pretty much a mandatory swap from the push button set up. For the 2 rides that I did with this lever, worked great. I probably would of kept this lever if I didn't have to get a new dropper (went from 150mm Rockshox to 125mm Fox Transer).
A couple reasons that initiated my move to a Fox Transfer was the need to buy all this "Bleed Edge" crap to do simple maintenance/installation on a drop post. Yeah, the 1x comes with the tool, but for someone that's not familiar with Rockshox hydraulically operated droppers, there's more stuff you need to buy like the fluid and syringes. Second reason, maintenance. Its hydraulic fluid. You have to bleed and flush it occasionally and it can get quite messy and expensive.
Like I said, its a great upgrade and I would of kept using it if I didn't need a shorter travel dropper post.
