Ready to get in on the fun of biking?
In Minneapolis, Minnesota, a group of young people who love bicycles have been trying to figure out how to make bicycles for everyday use and weekend rides without wasting money. They have continued to build tough, long-lasting, and fun bicycles with frames suited to each rider, and with the ability to install a variety of parts. Surly is a well-known manufacturer of bicycles made by such unparalleled bicycle enthusiasts.
The Preamble is a steel bike for everyday use, from paved roads to gravel roads. The Preamble is a steel frame that can be used for everything from paved roads to gravel roads, and it is a bike that can be used in your everyday life. Double-butted chromoly tubing strikes a perfect balance between comfort and rigidity, providing a smooth ride and the suppleness to withstand daily use.
Equipped with a rack, fenders, and two bottle cage pedestals, it is ready for commuting, riding around town, or even a short trip. The geometry is stable enough to ride over rough pavement without worry and easy to handle in everyday, stop-and-go situations. The frame's flexibility means that it will always be there for you, no matter how far or how long you travel.
The appeal of Preamble is its simplicity and choice. You can casually ride around town on the flat bars, or go for longer rides on the drop bars. You can load it up with baskets and bags, and the bike will still work quietly and unobtrusively. There are no extra bells and whistles, but the bike has a lot of blank space.
It's in the affordable price range of the Surly line, but its core philosophy is the same as the other models. This is a bike that makes you realize that "there are good roads even if they are not special occasions. This is a bike that we can confidently recommend as the first bike for those who want to experience the charm of steel.
