Went for a quick spin tonight and noticed play in my seatpost when I stopped at a gate after a few miles. Grasped the saddle to get a better idea and the seatpost separated leaving nothing protruding from the frame - luckily, I was stationary at the time.
I guess it's taken a while to get into this state as I haven't tightened the seat post collar recently. Anyway, I have a snapped Thompson seat post stuck in my Trek 69er Ali frame and I'm not sure how to get it out.
There are 3 slots in the frame at this point and I was thinking of drilling straight into the seat post, fixing a small bolt and nut to give me something to hit with a hammer in an upwards direction. Is this a mad idea - is there a better way?
