The Lucky Jack by DUKE is a very light and wide rim for cross country and marathon use.
With a weight of 330g (manufacturer), the weight is surprisingly low. Great added value has the dimensions of the rim. With 30.9 mm outside and 25.6 mm inside the rim not only offers excellent lateral stiffness, but also the tire optimum support width. Even at low air pressure, the driver (in) no spongy feel, since the tire can bend to the side worse. Grip and comfort of the tire increase remarkably! Of course, the rim can be driven with sealant Tubeless.
The rims are provided with an asymmetric rim profile, which causes a more uniform angle of attack of the spokes. This optimization of the spoke angle brings with it a multitude of advantages. The spoke tension on both sides can be better matched to each other, which is beneficial to the durability of the spokes and the entire impeller. The usually directional lateral stiffness is also adjusted, so that the impeller appears stiffer in itself.
For the rim is a driver weight limit (including clothing and luggage): from 90 kg!
