Im trying to identify my vintage road bike. I've had it for years and years, i thought it was a shimano untill i was informed shimano never made a complete.

So i thought i'd ask some people that live fore this stuff. i know nothing about this bike except, it used to have a sr headset(the aluminum has a crack in it(if its worth fixing ill buy another) everything(and i mean everything) on this bike is from shimano, except the brake handles, those are from a company called
"exige" or something like that. I can post more pictures of anywhere if needed. Also when i took it to the bike shop for new tires and tubes and a chain, i asked the owner(an old school bicyclist) if he had any idea what year it was, and he guessed it to be a 75'.





I'm also kinda looking at seling it, not right away, its to much fun to ride but in the future after i fix the headset and decide to get rid of it to fund my bmx habits what would ya'll recomend asking for it?
