Q: Ever used one?
A: No, thought not
Yes they’re expensive but so are most things on a mountain bike. It’s honestly one of the best biking purchases I’ve made.
I take your point, and am glad you are having a good experience with yours. However, until such time that I have a spare £200 lying around, I won’t be rushing out to buy one.
Things are expensive, but some things more so. In the big list of stuff on your bike that breaks/wears out, my standard seat post is pretty low down the priority list. The dropper variety just sound like more hassle, more expense and less reliable.
I take it these things are new technology then? Hence the price.
