ok, so i have two older roadbikes ones a singlespeed cheapy murray, the other i just picked up is a 1990 univega. I know univega is a good name brand, however the thing is pretty heavy even for a chromo frame. So i was gonna buy some lighter forks off a guy in town who sells older road bikes/ parts. However like i said they would be off a older 90s-or older roadbike. So what brands should i look for, or what style? Aluminum? or what? Sorry im new to roadbiking, and if i can get ideas on how to lighten it up that would be nice also. thanks!
