Review
Review
It's a bike that turns heads on the street, people asking where it was imported from. Very comfortable, fast, excellent vibration absorption, and the geometry allows you to attack any type of terrain with confidence and ease. (4/5) Juan Mejia. - INOX 316 Gravel.
F Duarte custom-made a Columbus steel gravel bike for me, and I use it for long stage trips as well as short training rides. The bike's comfort and performance on both paved and unpaved roads, with and without luggage, are outstanding. I'm very happy with this purchase! 5/5 Hugo Tomas - D89 Columbus
