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 you can tackle opens up in unexpected ways. The H 1900 SPLINE was designed with precisely this in mind, and now incorporates DT Swiss's renowned ratchet ring 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 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, transfers all of the power generated to the ground.
