Rim
An all-new aerodynamic and light rim shape, 30 mm height, 20 mm inner width and hidden nipples are the ingredients to let you reach new top speeds with ease.

Spokes
Pushing the aerodynamic advantage further are the DT aero comp II straightpull spokes, featuring a redesigned shape, making them faster than their predecessor.

Hub
The 370 hub now features the Ratchet LN system, and with its signature freewheeling sound, it will reward you at the end of every sprint.

Freehub body
The Ratchet LN System, thanks to the simultaneous engagement of each tooth, will let you count on its reliability while pushing hard on those accelerations.

Technologies

Aero+
The symbiosis of drag, handling and efficiency. When refining a wheel according to AERO+, the optimization of all parameters is subject to one single goal: higher speeds!

The Ratchet Technologies
Every ratchet has its purpose. Learn more about the different DT Swiss freehub systems. Each Ratchet System has its special characteristics, but they all provide the iconic reliability. This is a result of the simultaneous engagement of the teeth, creating far fewer point loads. Discover how the constructions differ and which common features they share.

Spoke technology
The production of high-quality spokes marked the beginning of the company. DT was synonymous with top quality Swiss spokes, even before the establishment of today‘s DT Swiss AG. To this day, DT Swiss spokes stand for durability and precision and are unrivalled thanks to their unique production process that combines lightweight with durability.

Nipple technology
The interface between spoke and nipple is highly important for the durability of a wheel. A good reason for DT Swiss to continuosly improve and fine-tune the DT Swiss nipple range in line with the different requirements of the various cycling-disciplines. All nipples are available with or without the locking system DT Pro Lock.
