My bike

Hey yall! This is my 2003 trek oclv 5500 that I got from my uncle last April. This is my first road bike but it has made me fall in love with cycling. This past summer I was trying to average around 100-200 miles a week (hopefully going to get more this year lol). Put about $1,300 into a new drive train, shifters, almost everything but the frame. I had to get a pic off the internet for the exposed raw red carbon lol. Lmk what you think I should do next!! I’m thinking new wheels and handle bars
