Hi, I'm new to the forum and would like some advice please. I have a Trek 5000 that I purchased new in 1998 ($1800) and I'm considering upgrading it for the second time. Last year I put Kyserium wheels, speedplay pedals and a sella italia seat on it ($600). Now I'm considering getting rid of the stock forks, threaded quill-stem and headset and replacing with an Easton or Reynolds 1" fork, a Chris King nothread headset, and a longer stem. I'm also looking at replacing the stock handlebars with Easton EC70 to go from 42cm to 44cm. Obviously this is going to be another fairly large investment. I love the bike and it's still extremely light and fun to ride. I don't really want to drop 2k on a new bike either. What would you do?
