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 you can tackle turns out to be far richer than you might expect. The H 1900 SPLINE has been designed with precisely this in mind, and now incorporates DT Swiss's renowned toothed ratchet technology. The Ratchet LN system spreads the combined forces of the rider and the motor over a larger surface area than traditional pawl freewheel systems, which also extends the system's service life thanks to lower peak loads. The 370 hub, paired with reinforced Hybrid spokes and a high-strength aluminium rim available in two internal widths, transmits all the power generated down to the ground.
