Sorry, I was struggling to describe the issue. So the post works fine with the lever – it stays up when you want it up and down when you want it down. But when it’s down, you can manually lift it back up and push it down again (without actuating it with the lever). This means on rough descents, it’s free to move, which causes it to knock against its lowest position. It’s annoying but I can live with it. I was just curious to know the cause of the issue and if there’s a fix.
