Brompton Brompton 1975 Edition C Line 12-Speed 2026 - Folding Bike
The signature thermal fade and gold highlights of the 1975 Edition reflect colours that emerge around the bright gold joints of a Brompton frame in the minutes following brazing. In this transformational process, metals fuse and cool to form a structure that is strong enough to last a lifetime. Each brazer’s work develops a distinct style over time, as unique as handwriting. They finish this bike with a robust, threepart, semi-transparent colored lacquer, allowing every unique detail to shine through.
Occasionally, without notice, manufacturers change product design and/or specifications.
