I had an ‘85 Trek 460, their entry level racer for weekend warriors. Not as light as I wanted but did discover the key to a lighter feel was in the wheels, tubes and tires. Put some fast rolling Michelin 23’s or even the Power Competition series 23’s. Great tires that will be a noticeable difference. I was using heavy Bontrager B sports 25’s. Then switching to Michelin 23mm Krylions, that first ride was eye opening and put a grin on my face.

Enjoy your season on a Trek, well built!
