For extended eMTB tours

When motor assistance meets human muscle power, the number of terrains a bike can conquer inevitably increases. The H 1900 Spline is made for exactly that and is now equipped with the tried and tested DT Swiss Ratchet technology. The Ratchet LN system distributes the combined power of driver and motor over a larger area than the earlier pawl freewheel hub system and thus increases the robustness of the system through lower load peaks. The 370 hub, combined with reinforced hybrid spokes and a robust aluminum rim with two internal widths, enables complete power transmission to the ground.

Highlights

  • Impeller specially designed for the needs of eMTB riders
  • Very stable and wide, aluminum tubeless rim adapted to a higher total weight
  • Robust DT370 hub with ratchet freewheel, also for switching operations under load

Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

Ratchet LN
Toothed lock washers instead of pawls. The simultaneous meshing of toothed lock washers ensures a larger contact area and a more even distribution of the load. The result: outstanding reliability. The modular design of the hub also enables the pressure angle and the freewheel body to be easily adjusted. With the Ratchet LN, DT Swiss pawl systems can be converted to the Ratchet system. To enable this conversion, the seal of the freewheel system was attached to the freewheel body and not, as with the other ratchet systems, on the hub shell.

Tubeless
All DT Swiss wheels are tubeless ready and the ASM versions are supplied with the tubeless tape and the corresponding valves fitted.

Pro lock
In the Pro Lock process, a two-component adhesive is injected into the nipple thread, which enables extremely durable impellers to be built. As soon as the nipples are screwed in, the adhesive is activated, which hardens completely after approx. 6 - 7 hours at room temperature. Repeated re-centering is possible without any problems, whereby the adhesive force decreases slightly with each re-centering.

Pressure angle
The pressure angle is the largest possible angle that the freewheel body can turn until the teeth of the freewheel body completely mesh and the hub shell is accelerated. In the opinion of DT Swiss, 36 intervention points represent the best optimization within the three-dimensional perspective in terms of reliability, weight and intervention points, taking into account factors such as suspension, maximum free travel (backlash) and pedal kickback.

camp
DT Swiss hubs are designed in such a way that they function optimally once they are installed in a bicycle. In order to achieve this, the clamping force created by the wheel fastening system must be taken into account when designing the hub. Optimal turning properties without adjustable bearing play.
