Crank Bros JoplinR 4

Up for sale is my Crank Bros. JoplinR 4 seat post. Working and looking great, I have had zero problems with this post in the past year. I was really skeptical af buying a Joplin because of all the bad reviews but, if you read them the are either terrible or awesome so when a co-worker said he was selling his and has had no problems I decided to give it a try man have I been happy. I would be keeping this post but it does not fit my new bike I just built. I figured even if I have a problem with it, it only costs $40 for CB to rebuild it. I work at a bike shop and have found that whatever post you buy they all need to be serviced, so i figured my total cost would be buying one that already has a reliable history and even if it broke my total cost would be less than buying one brand new. Soooo anyway 100mm of drop and a 31.6 tube diameter. Call text or message me Thanks
