I am new here and recently I got a Schwinn World off craigslist. I am wondering what its exact spec as I couldn't find it anywhere on the Google and that seller did not keep any of the paperwork. He said that the bike was about 10 years old. I found the serial number below the frame and it's GM835814. Also, it has a 12-speed Shimano Light Action (SIS) gear and 27" tires. Any idea guys? Here's the pictures. Any help would greatly be appreciated. Thanks!!
