The DT Swiss H 1900 Spline wheel is a reliable aluminum MTB wheel, now featuring Ratchet LN technology to extend e-MTB tours. When electric assistance meets the pedaling power of an experienced mountain biker, the range of accessible playgrounds is surprisingly rich. The H 1900 Spline was designed precisely with this in mind and now incorporates DT Swiss's renowned toothed crown technology.
The Ratchet LN system distributes the combined forces of the rider and motor over a larger surface area than that offered by ratchet freewheel systems, thereby improving system life through lower load peaks. The 370 hub, combined with reinforced Hybrid spokes and a high-strength aluminum rim, available in two internal widths, allows all of the power generated to be transmitted to the ground.
The + product:
- A tubeless ready aluminum hook rim is available in an internal width of 30 or 35mm, and a diameter of 29 ?or 27.5?.
- First wheel equipped with the Ratchet LN system, ensuring a distribution of forces over a larger surface, for increased durability.
- DT Hybrid 1 spokes have been reinforced and increase lateral stiffness and torsional stiffness of the wheel.
