If I've posted this in the wrong place, let me know.
I'm building a SWB recumbent from old bike parts. Project is going pretty well. Seat is nearly done and looking good, and the boom for the pedals is in place. My problem is the stem. It is the quill type. I need to get the handlebars up high enough that my legs won't hit them. I can't find a stem long enough, and can't figure out a good way to stretch the existing stem. Any suggestions?
