Here’s my latest (and hopefully last for a while) bike project – a 1971 Schwinn Super Sport. These bikes were fillet-brazed by hand. This type of construction is fairly uncommon in modern bikes. You can read more about these bikes here: http://sheldonbrown.com/schwinn-braze.html
This bike received a thorough cleaning and greasing. I converted the heavy one-piece Ashtabula crank to a modern 3-piece crank using an insert and sealed bottom bracket. I also upgraded most of the heavy steel groupset with decent vintage suntour parts from a more modern Schwinn bike that was converted to single speed.
It weighs in at 29 pounds as pictured. I find the ride quick, maneuverable, and fairly comfortable. The smooth fillets and bright yellow paint are quite lickably pleasing!
