H 1900 SPLINE® A reliable aluminum wheelset now with Ratchet LN technology for extended eMTB tours. When motor support meets human muscle power, the amount of terrain a bike can conquer inevitably increases. The H 1900 SPLINE is made for exactly this 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, thus increasing the robustness of the system through lower load peaks. The 370 hub, combined with reinforced hybrid spokes and a durable aluminum rim in two rim widths, enables full power transmission to the ground.
- Optimized for use on e-MTBs
- Tubeless ready aluminum rim
- optimal power distribution for more robustness
- reinforced DT Hybrid spokes for more lateral & torsional stiffness
When motor support meets human muscle power, the number of terrains a bike can conquer also increases. The H 1900 SPLINE wheels are made for exactly this and are equipped with the proven DT Swiss Ratchet technology. The Ratchet LN system distributes the power of the rider and motor over a larger area than previous pawl freewheel systems and thus increases the robustness of the system through lower load peaks. The wheels combine a 370 hub with reinforced hybrid spokes and durable aluminum rims to ensure full power transfer to the ground.
Tubeless technology
Tubeless tires offer some decisive advantages over the conventional combination of tire and tube. The tire can be ridden with less pressure without risking "snakebites" and therefore offers more grip. The lower pressure also ensures greater riding comfort. The absence of the inner tube means that there is no friction between the inner tube and tire and therefore less rolling resistance when riding off-road and over obstacles.
Pro Lock technology
The 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 enables 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 possible without any problems, although the adhesive strength decreases slightly with each re-centering.
Ratchet technology
The Ratchet System hubs are unique in that all the teeth of the two disks engage simultaneously every time. In the case of pawl hubs, the engagement surface is quite small. With the Ratchet System, on the other hand, the entire end faces engage with each other, which ensures a much lower point load. The result is the legendary reliability of Ratchet System hubs.
