1989 Schwinn Tempo

I purchased the bike before Seattle's Chilly Hilly in February at the annual bike swap. A bit rustier and less taken care of as I disassembled it--the negligence of a good bike was a bit angering. I repainted the fork as its paint was destroyed (how??). After the "as is" ride then tear down then cleaning, I got her dressed in modern 9 speed running gear and she aced the Chilly Hilly. Great ride! Love that steel feel. Parts were then swapped to another bike and her fate was again up in the air. A full 7400 series Dura-Ace opportunity came my way in the form of a cracked-at-the-bottom-bracket Centurion Ironman and here is the result. I love riding this bike even more than when it had STIs! Get in on some of this downtube shift action if you aren't already!

More Info:
With pedals, she is 24.5 lbs of stable speed with a real slot car-like hunkered down feel. Very very smooth. :) Oh, and that Ironman and this Tempo are identical in weight. So spend less on this sleeper Schwinn and still get stellar performance!
