HU 1900 Spline designed for durability. E-touring wheels are often ridden with an increased system weight, which puts considerable strain on the wheel and its components. This can lead to damage to the rim and spokes in the long term. The HU 1900 Spline has been designed and tested accordingly. Certified for a maximum system weight of 180 kg and specially designed for e-bikes, the wheel can cope with these increased loads: With a thicker cross-section and fitted with reinforced 2.34 mm spokes, these wheels are built to last. The 370 mm hub rounds off the package with the legendary 18-tooth ratchet system. The reliability of a wheel is based on the quality of its assembly. All wheels are hand-spoked by professionally trained wheel builders to ensure the same spoke tension in every riding situation.
