Both bikes are from 3rd party sellers that don't have too much info. on the bikes. They seem to be in good condition though, I think the Trek is mid 1980's and the Premio is early 90's. I won't be riding this bike more than 30-40 miles a day, so it is not important that i get the PERFECT bike for me. Im more curious if you think a Trek 620 for $150 + roughly $75 to fix up well is better than buying a Premio for $350. Plus, its a lot more fun doin' a fix up!
