I scored a new bike at a rummage sale this weekend. A Schwinn Tempo. It was a little dusty, but cleaned up very well. Not so much as a scratch in the paint and all the metal parts cleaned up like new. It looks like it just came from the LBS. I repacked the bottom bracket and cleaned her up. I put on some SPD pedals, a water bottle cage and a Mity 3 computer and she's ready to rock. She's got Sugio(?) gear and shimano components. The bike shifts and brakes very well. It even has indexed shifting. It has 700MM rims with 700 * 28 tires which are in good shape. They are on Belgium built Weinmann rims. On the Schwinn emblem it says Chicago and it has a decal which has a reference to Columbus tubing. I laid out a princely $15.00 for this bike and feel like I stole it. It rides really nice. Any comments on the Tempo in general? Where do I find the serial number and where do I look to find out when it was built?
