The suspension seat post on my Fold XS bike seems to be binding up. When I took off the seat post and compressed the suspension post, it seemed to be binding when released, meaning it was traveling smoothly. I have a seat suspension on my Cannondale and when doing the same procedure, it operated smoothly. Has anyone experienced this same problem? I'm not really sure how to address this on the Facebook page so I'm reaching out to forum members before I ask Sondors directly.
