HU 1900 SPLINE® Built to last. Touring e-bikes often have a high system weight, placing considerable stress on the wheel and its components, which over time can damage the rim and spokes. The HU 1900 SPLINE has been designed and tested to avoid this risk. Certified for a maximum system weight of 180 kg, this e-bike-specific wheel copes with heavy loads without any problem. Built to last thanks to its thicker rim section and reinforced 2.34 mm spokes, this model is also fitted with the 370 hub, featuring the legendary 18-tooth Ratchet System. The wheel's reliability comes from the quality of its build. All our wheels are hand-built by qualified professional wheelbuilders, ensuring even residual spoke tension in all circumstances.
