New guy here. Thought I should introduce myself by showing a bike. It was sold to me as a 1948 with a bunch of incorrect parts on it. I've got it about as period-correct as I want it right now. One day I might get the last few bits...
Cinelli 15 bars
Gaslo bar plugs
Cinelli 1 stem
Reg bottle cage
Beborex levers (might not have been released until 1950?)
Universal 39 brakes (I took the period-correct pads off cos this is a rider)
Sheffield pedals w/ Christophe clips and Binda straps
Regina 4 speed
Campag spoke protector
Campag Cambio Corsa gear changer
Unknown original spokes
Super Champion rims (from the 70s. It came with original rims but they weren't fit for riding. I'm fine with incorrect rims and pads and stuff on a rider - safety first, kids!)
Unknown steel seatpin
Brooks B17 narrow
I love this bike. Rides like a champ! Shifting isn't that hard so long as you don't try it on a downhill. I rode it in the Melburn-Roobaix in my town last year: 80km+ with a dozen sections of cobblestones. It held up well with my heavy butt over the rough stuff, though I did drop the chain a few times.
It occasionally gets clipless pedals and gets used on the commute. Shifting with a backpack on is pretty crappy, though.
