DT Swiss H 1900 Spline Hybrid E-MTB Rear wheel - 29" - 30mm
A
highly reliable and durable aluminium wheel full of DT Swiss
quality now with Ratchet LN 18T Technology for extended eMTB tours.
When
motor assistance and leg power meet, the range of terrain a bike can
conquer grows almost exponentially. The H 1900 SPLINE is designed for
this, now upgraded with the famous DT Swiss Ratchet technology. The
Ratchet LN system distributes the combined forces from the rider and the
motor over a larger area than the previous pawl freehub systems,
increasing the systems’ durability thanks to lower load peaks. The 370
hub enables full power transmission to the ground with reinforced hybrid
spokes laced to a resistant aluminium rim.
Redesigned hub shell: Due
to the battery and motor, eMTBs tend to weigh more than traditional
MTBs of the same category. eMTBs are not ridden less hard; in fact the
opposite is often the case, as tours are longer and the load on the
components increases. In addition, the transmitted torque of the motor
is higher than with conventional MTBs. The hub shell was completely
redesigned for the new hybrid generation with these points in mind.
Ratchet LN:
Equipped with the 370 hub featuring the Ratchet LN freehub system. This
system allows for uniform load distribution over a large surface, where
the whole front face engages, creating much smaller point loads. This
provides the legendary reliability of the Ratchet System hubs. These
ratchets are optimised for e-bikes: Made of hardened steel and equipped
with 18 teeth, they offer high durability.
Resilient rims: Modern
eMTBs are developed to go faster and harder. Our Hybrid wheels are
proven to support a maximum system weight of 150 kg. DT Swiss rims have
additional material right where it matters. They have reinforcement on
the external central part of the rim, because this is where the biggest
loads are when the bike supports its and the rider’s weight. The forces
exerted on the wheels come from the top and go down vertically to the
ground. That is to say that the spokes which are on the lower part at
the time of the rotation, support most of the weight. Therefore, the
profiles of the rims have not changed and remain the same as the ones
that have been tested and approved on the most challenging trails. These
rims are available in a variety of internal widths so that every rider
can select the features they want and get the best grip and traction
possible.
Reinforced Spokes: When
it comes to dynamic stress, the same logic for the rim also applies to
the spoke head: under high loads, the spoke heads experience a
continuous dynamic load. In order to address this potential weak spot,
DT Swiss has reinforced the spoke head to 2.34 mm to ensure resistance,
even at a high total system weight. The output tension of the spokes
also plays an important role. It is therefore essential that residual
spoke tension is maintained in every riding situation, in order to keep
the peak load low on the individual components of the wheel. This makes
precise and knowledgeable wheel building of paramount importance. All DT
Swiss wheels are assembled 100% by hand in order to pay particular
attention to the tension of the spokes.
