It is not just the bike that got older since around 1985 but you did too. That makes a lot of difference in how you perceive riding the bike. I bought a Motobecane Le Champion road bike in 1973. It was their top-of-the-line production bike at the time. It weighed 21 pounds and was equipped with first rate components. I worked for a bike shop at that time so it was properly fitted and set up. It was a great pleasure to ride it when I bought it but as the years went on it got less fun to ride. It was not because the bike became outmoded or only had 15 speeds. It was me. I developed cyclist palsy from being an avid cyclist and motorcycle rider. Eventually I tried mountain bikes (still own two) but that wasn't much better. You can get a new bike with a less aggressive geometry (less weight on hands and shoulders) but eventually time may catch up with you. BTW, I tried giving the Motobecane away to friends who ride but nobody wanted it so I gave it to a charity that takes donated bikes for people who need transportation but don't have a car. It came back to the charity within a week because the new owner wanted something with fatter tires and more comfort. He was happy with a BSO rather than a quality bike with high pressure, narrow tires. I still ride but now ride a recumbent trike because even though it is heavier than the Motobecane it is way more comfortable.
