The DT Swiss 350 hubs are all about performance on a budget. You get the same exact internals found in the venerable 240S, the standard against which other hubs are measured. The 350 hub line up is designed with durability in mind. No Tool concept means less time in the shop, and more time in the saddle.
Boost compatible hubs have an enhanced flange distance. This has significant advantages: a flatter spoke angle and improved symmetry allow building a stiffer and stronger wheel, always an advantage, but especially for larger diameter wheels in challenging terrain.
