I completed the Roger, a vintage French bike frame that was given to me a few years ago when I got back into bikes. It was a mess when I got it and the rear triangle was bent enough that the rear wheel sat in the frame plenty crooked. John Adams (the bike shop owner, not the president) taught me how to bend it back into alignment. That blew my mind since I thought I'd have to find a frame builder to do that... now I know how to do it! I finally built it up, and took it for a test ride. I hate it. But I passed my supply chain management class with an A.
