I am considering buying a used Trek 5000 OCLV Carbon bike. I don't really know a lot about it except that the seller says it is 'awesome shape'. I did a little research on the web and it looks like this is a pretty good bike. Asking price is around $9oo. Do you guys think this is reasonable? and is this a good bike? I am a biker who likes to go fast on the bike paths in our city and will ride 3 to 5 times a week during the spring, summer, and fall, 10 to 12 miles at a time. Thanks for any input.
