    The asymmetrical shape enables more even spoke tension, which further increases the rigidity of the entire Wheel.


    Application: Road, Gravel, Cross Country, Trail
    Weight incl. nipple: approx. 5.45g (1 piece)

    The wing spoke made of cold drawn Sweden steel has an elliptical shape which takes advantage of the flat, light and aerodynamically more favorable but weak aero spoke and the stronger but less aerodynamic and heavy classic round spoke. This gives it the diameter necessary for torque transmission and at the same time favorable and superior aerodynamic properties with low weight!

  • The nipples are made of brass in order to achieve the best possible and long-lasting result in terms of color. The robust material is insensitive to corrosion and does not stick to the thread of your spokes, so that re-centering is still possible without any problems even after years of use. In addition, they are neither attacked nor damaged by any sealing milk that may have got into the rim well.

    Weight per piece: 1.0g

Wheelset 28" Disc RR | Carbon-Ti Road Straightpull Center Lock hubs | Duke Carbon rims

intended use : Road bike RR, Gravel GRV

Road cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Duke carbon rims and carbon-Ti hubs should therefore always be shortlisted. The balanced selection of components guarantees you high reliability and a long service life.

The bodies of the X-Hub SP hubs are CNC-milled and rotate around a multi-butted aluminum axle. With a diameter of 17 mm, this brings a decent stiffness to the hub. High-quality, double-sealed ball bearings are installed, which ensure a permanently silky smooth run. The axle play can easily be adjusted by hand from the outside. The new pre-load adjustment ring is now easier to use.
The freewheel on the rear wheel hub uses four pawls, each with three teeth, in a 56-tooth titanium ring to be able to withstand the acceleration of performance-oriented drivers.
The main advantages of straightpull hubs, in addition to the more modern design, are spokes that are built without contact and do not cause any unpleasant noises and spoke heads that cannot work into the spoke flange.

The carbon rims from Duke from France stand for excellent workmanship and low weight. Thanks to the SLS2 production technology developed by Duke, the latter could be reduced by around 10% compared to other rims, while at the same time increasing durability and stability. The use of high-modulus carbon fibers also improves the inherent damping, which benefits increased driving comfort. The modified structure also enables the unrestricted use of modern tubeless tires.

Please note the maximum permissible system weight in the rim's selection menu under "Show description".

Impeller construction at R2-Bike

Our wheels are assembled entirely by hand by our wheel builders. During the entire construction, it is important that not only the concentricity is right, but also that the spoke tension is as even as possible. This special care allows us to give a lifetime guarantee against broken spokes, as long as this is not caused by violence.

Furthermore, the following services are already included:

You get a universal wheel bag for all common sizes.
You get a replacement spoke with nipples in all required spoke lengths, so that you can repair the wheel at short notice after an accident.
You get a free initial inspection of the impeller, with the resulting work being completely free. Only shipping costs are charged.
You get a crash replacement promise: If your wheel is damaged due to force majeure, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
