  • H 1900 SPLINE

    When motor assistance meets human muscle power, the number of terrains a bike can conquer inevitably increases. The H 1900 SPLINE is made for just that and is now equipped with the proven DT Swiss Ratchet technology. The Ratchet LN system distributes the combined power of rider and motor over a larger area than the previous pawl freehub system, increasing the robustness of the system through lower peak loads. The 370 hub, combined with reinforced hybrid spokes and a resistant aluminum rim in two jaw widths, allows full power transmission to the ground.

    Inside, the Ratchet LN uses the same mechanism as the well-known Ratchet system. The difference in the systems is in the placement of the seal. To ensure the convertibility of ratchet hubs, the seal had to be attached to the freehub housing of the Ratchet LN hubs. On hubs with the classic Ratchet system or Ratchet EXP, the seal is on the hub body.

    Ratchet System hubs are unique in that all the teeth of the two discs engage simultaneously each time. In the case of ratchet hubs, the engagement area is quite small. In the case of the Ratchet System, however, the entire face surfaces engage with each other, resulting in a much smaller point load. The result is the legendary reliability of Ratchet System hubs.
