The Lucky Jack by DUKE is a very light and broad rim for cross country and marathon use.
Weighing 330g the weight is surprisingly low. Great value have the dimensions of the rim. With 31 mm outside and 24.8 mm inside the rim provides not only an excellent lateral stiffness, but also the tire optimum support width. Also at low air pressure, the driver (in) no spongy driving feel, as the tires can snap off bad side. Grip and comfort of the tire increase remarkably! Of course, the rim can be driven with sealing Tubeless milk.
The wheels are provided with an asymmetrical rim profile, which requires a more uniform pitch angle of the spokes. This optimization of the spoke angle brings a number of advantages. The spoke tension on both sides can be better matched to one another, what is the shelf life of the spokes and the entire impeller conducive. The normally directional lateral stiffness is also adjusted so that the wheel appear rigid in itself.
For the rim a Rider weight limit (incl. Clothing and luggage) applies: 90 kg!
