Trying again with "flat" bars for the mixte.
I cut them down and inch and a half on each side for a 3" total removal.
Ended up with this, about 1/4 of the way into the job. Had to finish with a hacksaw. I'm going to pick up a new tubing cutter, and probably take a smidgen off on each side just for clean-up.
Had this adjustable quill stem in my stash. It came off a garbage bin bike, and looked much different, covered in flat black rattle can.
There's the end result. It's becoming quite the comfort ride. I want to replace those cushy cut-up grips for something a little firmer, and get some bar end caps.
