Slots had been cut in the remainders of the post in my Richter frame and last night I was knocking a chisel in there to pop the post out. Chisel broke! Post is now wedged harder still in the frame. Mechanic at work set to it today with a big screwdriver and a hammer and I appreciate his efforts. However the post is STILL in the frame and now the seat tube has a split in it. Any takers for a DX groupset?
