Product details


DUKE Rim 29 "Lucky Jack Ultra SLS2 Carbon UD tubeless ready

So far, the Lucky Jack Ultra SLS2 is the lightest wheel developed by DUKE for cross country and marathon use.
With ultra-light 275 grams (manufacturer), the weight is surprisingly low. Great added value has the dimensions of the rim. With 30 mm outside and 24.5 mm inside, the rim not only offers excellent lateral stiffness, but also optimal tire width for the tire. Even when the air pressure is low, the driver does not have a spongy feeling because the tire can bend off to the side. Grip and comfort of the tire increase remarkably! Of course, the rim can be driven with sealant and tape tubeless.

A new manufacturing process reduces weight by about 10% compared to the Duke Lucky Jack while increasing rigidity and stability.

The rims are provided with an asymmetric rim profile, which allows a more uniform angle of attack of the spokes. This optimization of the spoke angle brings 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 is stiffer in itself.

For the rim is a system weight limit (driver including clothing, bike and luggage): from 90 kg!

3 years warranty on carbon rims
Duke selects the materials used very carefully to offer you the best possible product. Therefore, the quality standards for all products, subcontractors and partners are very strict. Duke guarantees that over the period of three years, the offered rims have no hidden defects. However, improper installation or use of the products invalidates the warranty.
