H 1900 SPLINE® A reliable pair of aluminium wheels, now featuring Ratchet LN technology to extend your electric mountain bike rides. When electric assistance meets the pedalling power of an experienced mountain biker, the range of terrain open to you is far richer than you might expect. The H 1900 SPLINE was designed with exactly this in mind, and now incorporates DT Swiss's renowned ratchet ring technology. 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 lifespan 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 of the power generated down to the ground.
