I also have 3 Twentys but when I travel I use my Bike Friday. I have had it for 25 years and it is light years lighter than any Twenty. They a made in Eugene Oregon so for you it wouldn't be hard to visit Bike Fridays plant and see how they are made. You give Friday the measurements off your favorite ride and they will give you a bike that dupicates that bikes riding. The make a bunch of different models for you to choose from.
