My 1979 customized Schwinn Varsity had a rear Velocity Chukar rim go bad after about 20 years of riding. Took me a year to purchase new rims in silver, install them and start riding the bike again. Took her out this evening to the Port of Sacramento. So far so good. As you can see I took a Schwinn Varsity, got rid of most of the original parts. They were pretty worn when I got the bike and replaced everything with nice new parts. I used a 180mm Profile crank and sprocket. It is 1x10 with a Shimano Deore MTB rear derailleur. Microshift SIS handlebar shifter on a S and M Bruzer handlebar. I have 700C x 40mm Schwalbe Marathon Pro tires on it. Not a lot of room in back for that tire but the front fork clears the tire well. Tektro 559 sidepull brakes. These brakes are terrific. Powerful like disc brakes and quiet. Pedals are Velo Orange platforms. My favorite bicycle. Just celebrating its return.
