H 1900 SPLINE® A reliable pair of aluminium wheels, now featuring Ratchet LN technology to extend your e-MTB rides. When electric assist meets the pedalling power of an experienced mountain biker, the range of terrain open to you turns out to be far richer than you might expect. The H 1900 SPLINE was designed with exactly this in mind, and now incorporates DT Swiss's famous ratchet system. The Ratchet LN system spreads the combined forces of rider and motor over a larger surface area than traditional pawl freewheel systems, which also extends the service life of the system thanks to lower 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.
