When motor support meets human muscle power, the number of terrains a bike can conquer also grows. The H 1900 SPLINE wheels are made for exactly that and come with the proven DT Swiss Ratchet technology. The Ratchet LN system distributes the power of rider and motor over a larger area than previous pawl freewheel systems and thus increases the robustness of the system by lower load peaks. The wheels combine a 370 hub with reinforced hybrid spokes and durable aluminium rims to ensure full power transfer to the ground.
Tubeless tires offer some decisive advantages compared to the conventional combination of tire and tube. The tire can be ridden with less pressure without risking "snakebites" and thus offers more grip. The lower pressure also provides a more comfortable ride. The absence of the tube means that there is no friction between the tube and the tire, and therefore less rolling resistance when riding off-road and over obstacles.
DT Pro Lock spoke nipples prevent the spoke-nipple connection from loosening on its own. A patented two-component adhesive is injected into the nipple thread, which allows the construction of extremely durable wheels. As soon as the nipples are screwed in, the adhesive is activated and then hardens completely. Repeated re-centering is easily possible, although the adhesive strength decreases slightly with each re-centering.
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 area of engagement 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.
