Discount DT Swiss HU1900 Spline 29″ Hybrid Utility Disc Brake Front Wheel

Description

The DT Swiss HU1900 Is Built To LastAs a result of recent developments in electric motors and pedelec concepts, it is now possible to transport even larger loads while covering longer distances, often also on rougher tracks. However, this results in higher loads and charge on the wheels and their components. Hybrid Utility wheels by DT Swiss have been specifically developed and tested to cope with these increased physical strains. With an approved maximum system weight of 180kg, this DT Swiss HU1900 Spline 29″ Hybrid Utility Disc Brake Front Wheel will provide long-lasting reliability and trust to the user.Hybrid WheelsLoads on e-touring bikes tend to be higher as the system weight is generally higher than on a classic, non-motorized SUV, trekking, or mobility bike. Additionally, these e-touring bikes can carry a heavy weight on longer distances with less effort for the user. Accordingly, DT Swiss has Hybrid-specific test requirements, based on the application range of ASTM F2043 Condition 2. DT Swiss Hybrid Utility wheels must pass several tests, which are specified in the DT Swiss internal test standard. The applied test methods reflect higher loads and an increased quantity of load cycles compared to other wheels, to ensure sufficient strength and durability under the demanding e-touring riding conditions.Hybrid SpokesA bicycle wheel in motion faces different load cases. For the spokes, the most common load is a tensile force. This force may vary from case to case, for example, for a single rotation of a wheel in use, each spoke will face different and changing tensile forces. These increased loads on the spokes primarily occur due to higher radial forces on the wheel and higher drive and brake torques. To face the specific higher requirements of a Hybrid wheel, the DT Swiss Hybrid spokes are reinforced at their head, resulting in a 30% stronger tensile force resistant spoke compared to a classic spoke.Hybrid HubsTo bring a heavy e-touring bike into motion in a short amount of time requires high driving torque in some cases. To slow down again, the braking will result in a braking torque through the wheel. The higher system weight and the increased amount of load cycles carry during use also leads to higher loads acting on the hub. The additional motor power leads to higher drive torques. The higher system weight leads to higher brake torques, which are necessary to decelerate an e-touring bike.
