Is the Trek 520 all original equipment? If you want to check specs, google a search for '1999 Trek 520', and go to epinions.com site (should be first site showing) and check details. Also be aware that Trek had a recall of the ICON handlebar stems that year on their 520s. I also have an '84 Trek 520 that is just a great bike--that year they used a longer chainstay on the 520s. Mine was a thrift store find--$35, w/ original equipment & in excellent condition except for some paint stratches on the top tube. Sometimes you win the lottery!
