H 1900 SPLINE® A reliable pair of aluminium wheels, now featuring Ratchet LN technology to take your e-MTB rides further. When e-bike assistance meets the pedalling power of an experienced mountain biker, the range of terrain you can tackle turns out to be far wider than you might expect. The H 1900 SPLINE was designed with exactly this in mind, and now incorporates DT Swiss's renowned ratchet technology. The Ratchet LN system spreads the combined forces of rider and motor over a larger surface area than pawl-type freewheel systems, which also extends the life of the system by reducing peak loads. The 370 hub, combined with reinforced Hybrid spokes and a high-strength aluminium rim available in two internal widths, transmits all the power generated to the ground.
