    The asymmetrical shape on the rear wheel enables a 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 "RR | Extralite Road hubs | Duke aluminum rims

intended use : racing bike RR

We also have wheels in our range for traditionalists with proven rim brakes. The combination of Duke aluminum rims and lightweight Extralite hubs should always be on the shortlist. The balanced selection of components guarantees you a high level of reliability and a long service life.

It has been known for a long time that the Italians around Extralite create small CNC works of art. With the development of the Cyberhubs, they have outdone themselves. The hub body is CNC-milled extremely complex from high-strength 7075TX aluminum. This rotates around an aluminum axis with double-sealed, smooth-running deep groove ball bearings. With the spoke flanges positioned very far outwards, the rigidity of the wheel is extremely increased without additional weight. The revised micro-tuner enables quick and easy bearing preloading without tools. Two titanium pawls work in the freewheel body in the rear hub, which simultaneously engage in a 32-fold titanium toothing.

The excellently processed Duke Road Runner rims are real multi-purpose rims. They are light enough to climb any mountain, durable to enjoy your wheel for many thousands of kilometers and very stiff so that every turn of the crank is converted directly into propulsion. The rims are tubeless ready and have a large inner width so that wider tires can also be safely mounted.

Wheel construction at R2-Bike

Our wheels are completely assembled by hand by our wheel builders. During the entire construction process, it is important that not only the concentricity is correct, but also that the spoke tension is as even as possible. The special care allows us to give a lifelong guarantee against broken spokes, as long as this was not caused by force!

You will also receive the following services for our balance bikes:

A universal impeller bag for all common sizes.
A spare spoke + nipple in all required spoke lengths to be able to repair the wheel at short notice even after an accident.
A free initial inspection of the impeller, during which the resulting work is completely free! Only shipping costs are charged.
A crash replacement promise. If your wheel is damaged due to force majeure, we will rebuild your wheel once. We grant a 100% discount on all labor costs and only charge the material!
