    Seat Tube?

    About half way down my seat tube there's an obstruction that prevents me from dropping my post all the way down. It looks like a pipe joint? Is this by design? 2011 Hei Hei 29 SE

    How far down is it compared to the shock pivot?

    Could be a protective sleeve to keep a user from putting a seat tube too close to the shock pivot. Alternative possibility is someone used a seatpost shim in the frame, accidentally lost it down the seat tube, and it's stuck by the pivot area.

    It is just below the shock mount, where the bottom weld is (see image below, finger point). I'm guessing it's an added tube to give more strength to the bottom bracket? I'm trying to figure out what size Fox Transfer Dropper to buy, 150mm or 125mm (external). By using Fox's calculations, I am shy by 4mm for the 150... Thanks for your help.
