I have a vintage bicycle that has become difficult to ride. First, I can no longer shift it while mounted. This is not a major deal, people ride single-speed bicycles every day. Dismount, select gear, shift, remount. But I am 77 with an inoperable broken scapula and riding drop bars for any distance is "uncomfortable". But damn, I love this bicycle.
So I bought a set of vintage "condorino" style Italian upright bars. I did not want to totally bastardize the bike for the next owner, so I have two sets of cables and housings attached to the bars. I cut three 3/4" long pieces of thin aluminum tubing and rewrapped them under the top tube tape. If I want to switch, I can just remove the cables at the brakes and pull them through, and switch out the stem, bar, brake lever assemblies.
Then I was left with road peddles on a bike that would likely be ridden with street shoes. (The fenders are contemporary, but the frame has wear marks and threaded fittings so it may have been a street bike anyway.
Johnny Pergolizzi showed up with set of really clean Way-Assauto pedals. The original pedals (and stem) are the only original things that a little rough on the bike, so I bit.
While I was Googling Way-Assauto history, another set of vintage WAY pedals showed up on eBay, which are basic platform pedals. Man, I had no idea the animal even existed! They are currently on the way to 1410 Oakwood.
So I will have two iterations of a 1950 Italian daily rider.
