DT Swiss has expanded its Degrees of Freedom (DEG) hub technology to include the 350 and 370 Ratchet hub platforms. The new kits allow cyclists to customize pedal kickback mitigation through adjustable engagement settings.
Why it matters
The technology decouples rear suspension movement from chain tension, which helps riders maintain better control during heavy compression. This upgrade allows enthusiasts to fine-tune their bike handling by adjusting the degree of engagement based on terrain.
The standard upgrade kit features a 54-tooth system with 0-degree and 14-degree engagement options, while the specialized race kit offers 90T engagement. Configurable settings include 0°/40° for downhill and 10°/30° for enduro use.
The players

The details
Users can switch between engagement settings by reversing the positions of the inner and outer ratchets. The system is designed to handle high-torque e-MTB loads while providing micro-adjustment options for suspension tuning.
