Quando LThe engine assistance and the power of the cyclist’s legs meet, the range of land that a bicycle can explore and conquer grows almost exponentially. The 1900 Spline set is designed for this reason, now updated with the famous DT Swiss DTA crown technology. The Ratchet LN distributes the cyclist’s combined forces and the engine on a wider surface than previous free wheel systems with nightlies, increasing their useful duration thanks to lower load peaks. The hub 370 allows you to transfer all the power to the ground, with reinforced hybrid rays connected to a robust aluminum circle, available in two internal widths.

Technologies

We believe in the art of engineering and in the continuous search for the most sophisticated solutions during product development. Continuous innovation and search for perfection: this is this L’Idea that underlies the work of the technicians and engineers of DT Swiss.
