This dropper post was only used for a part of one season and works perfectly. There are some minor scratches on the insertion tube which should be hidden by your seat post. As I've been adjusting the fit on my mountain bike, I needed to lower the seat more than this post allows. It is currently shimmed to 190 mm but the shims can be easily removed. OEM grease and additional shims go with the sale. Retail price is $270.
