Shortening a Seat Tube
I have a steel tandem with a rear seat tube that sticks out above the top tube, with an external clamp for the seatpost. In order to accommodate a shorter stoker, I'd like to cut about 1 cm from the seat tube. How can I make a good cut without ruining the frame? And do I have to lengthen the slot facing the rear of the bike? Or should I take the tandem to a framebuilder to do all this?
