H 1900 SPLINE® A reliable pair of aluminum wheels, now featuring Ratchet LN technology to extend e-MTB rides. When electric assistance combines with the pedaling power of an experienced mountain biker, the range of accessible terrain reveals an unexpected richness. The H 1900 SPLINE was specifically designed with this in mind and now incorporates DT Swiss’s renowned ratchet technology. The Ratchet LN system distributes the combined forces of the rider and the motor over a larger surface area than that offered by standard ratchet freewheel systems, thereby extending the system’s lifespan by reducing peak loads. The 370 hub, combined with reinforced Hybrid spokes and a high-strength aluminum rim—available in two inner widths—ensures that all generated power is transferred to the ground.
