I have been cycling on a Centurion Pro Tour that was constructed sometimes in the 1980's - probably late 1980's, but still.
It works great. It coasts downhill far faster than my hybrid, it doesn't weigh very much and I have definitely gotten perfomance results from riding it.
But, it is still from the 1980s.
It kind of forces you to ride in an areo position. Once, I felt a pull in my back when I was riding up a hill (the topographic lines are very close together on that thing), and it took me days before I could ride again. Sometimes, I feel it a little in my elbows.
It is worth it to look at a new bike? My budget is really only 500USD or so. Or am I just not adjusting it properly?
I know it's a narrow question on the fact of it, but I can't be the only guy with a decent ancient bike who would like some opinions one acquiring a new one.
My bike shop told me to I'd benefit from a new one, but hey - they are trying to sell bikes.
