In my experience, the Alps are where you don’t need a dropper post as much. Since the downs are much longer (and the ups too!) it’s not such a chore to stop and drop the post. But at home, with more frequent, short ups and downs, I tend to adjust my post height (with my Reverb) multiple times in any one ride.
My advice, for what it’s worth:
125mm drop is much better than 100mm. I have one of each , and the 125mm is much, much more usable.
Remote is really worthwhile.
The Gravity dropper is ugly as sin, but GD are great folks, very helpful and the product is simple stupid. (I still prefer my Reverb though – best bit of kit since I discovered disc brakes).
