Ya I'm kinda lost what to do. The 620 looks to be an '84. I am leaning towards just selling the rb-1 and walking away from this trade. Using the $$ to buy something. What to buy is the question. I really wish this frame was my size. How much do you think the rb-1 would be worth? I will sell it cl, Im in SF, the market is pretty good. I'm hoping with the money from this plus $300 or so I can get a capable road bike with ability to add a rack for some overnite rides. But honestly it will be 98% road rides in marin trying to keep up with $5k bikes (And passing them) and few tours a year. So I don't know if getting a touring specific ride is the right call. FYI my daily riders are a Fisher Carbon pro caliber from mid-late 90's- great for ripping around the city, and a SSp Nishiki international with lotsta leather for style points. So this bike will be for rides and tours only- function over fashion on this one. thx for any advice it is appreciated.
