Fully working Maverick Speedball seatpost remote version.
3" drop, 385mm length, 30.9mm diameter.
Seal is good and it drops and returns fine, some slight side to side play, but no worse than my newer X-Fusion post.
Comes with an unused X-Fusion remote.
£55 posted first class.
IMO these (and the CB Joplins) are unfairly maligned - never had any problems with this at all as long as I wiped the seals after every ride and occasionally unscrewed the collar and gave it a grease. Just the basic stuff you'd do to your forks, but people seem to forget to do to a seatpost!
Too many bikes, not enough time!
