I love NOT having a dropper post!

I've put it through the wringer

I just don't see the purpose of dropper posts. My new Spesh SJ came with a nice one and it worked like magic, but I didn't see the point of casting spells every time I came up on a big downhill. I don't have a 34.9mm diameter regular seatpost, but I do have a 30.9mm diameter and its a super light carbon post. Now I'm literally hundreds and hundreds of grams lighter! Literally lost 3/4 of a pound! As well I can concentrate on having fun rather than trying to remember to drop my boat anchor seat post (600 ugly grams! ) This is a light beautiful seatpost spacer that suited my evil purposes.
