The Dt Swiss H 1900 SPLINE 27.5 35mm 12x148 Disc 6T Micro Spline Rear Wheelis a mountain bike wheel that offers the perfect balance between durability and efficiency.
Since the introduction of the first generation of Dt Swiss Hybrid wheels, e-bikes, their riders, and their range of uses have changed significantly. Not only have average riding forces increased significantly, but more powerful batteries have nearly doubled the average ride duration. As a result, modern e-bikes and their components must now prove themselves in these new conditions.
With the current line of Dt Swiss Hybrid wheels, the Swiss team at Dt Swiss has taken these developments into account and, drawing on 27 years of experience, has adapted the E-Bike-specific wheel series to handle higher loads. The H 1900 wheels offer you an affordable introduction to Dt Swiss Hybrid wheel sets without compromising on durability or reliability.
Robust Rims
The insert-molded aluminum rims (sleeve-bonding process), with their generous 30-millimeter inner tire width, provide excellent support at low air pressures. To accommodate a maximum system weight of 150 kg (rider, luggage, and bike), the rims have been reinforced at critical points. In particular, the inner area around the spoke holes—which is crucial for power transmission—has been given a thicker wall. Of course, the rim profile is designed for Tubeless use and comes with Tubeless tape and a matching Tubeless valve.
Dt Swiss 370 Hubs
To handle the higher driving forces of the E-MTB, the Dt Swiss 370 hub features a specially hardened steel cassette body. Its Ratchet LN pulley system distributes the combined power of the rider and the motor evenly, without load spikes, at a rate of more than 18 teeth per wheel revolution.
Dt Swiss Hybrid 1 Spokes
The Dt Swiss Hybrid 1 spokes were specially developed for use on E-MTBs. The straight-pull spokes have been reinforced, particularly at the spoke heads. With a maximum tensile strength that is 30% higher than that of conventional MTB spokes, they can better absorb higher drive and braking torques, thereby ensuring the wheels’ permanent lateral and torsional stiffness.
Pro Lock Technology
In the Pro Lock process, a patented two-component adhesive is injected into the nipple thread, enabling the construction of extremely durable wheelsets. As soon as the nipples are screwed in, the adhesive is activated and cures completely after approximately 6–7 hours at room temperature. Repeated centering remains possible without any issues, although the clamping force decreases slightly with each re-centering.
