DT Swiss 350 Hybrid Boost Hub
DT Swiss 350 Hybrid Boost sits as the market-leading, workhorse option for e-bike thru-axle hubs thanks to a proven ratchet-based drive design, reinforced internals for e-bike torque, and modular freehub body options (Shimano HG, Micro Spline and SRAM XDR variants). It balances durability, low maintenance and a midrange price point, offering a more cost-effective, serviceable package compared with boutique high-engagement hubs from Industry Nine or the premium Chris King units while delivering lower parasitic drag than some sprag-clutch designs.
