    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.

Wheelset 28 "Disc GRV | Carbon-Ti Road Straightpull Center Lock Hubs | MCFK Gravel Carbon Rims

intended use : Gravel GRV

This lightweight yet stable wheelset is the first choice for the committed gravel or cross biker. The balanced selection of components guarantees you a high level of reliability and a long service life.

The bodies of the X-Hub SP hubs are elaborately CNC-milled and rotate around a multi-butted aluminum axis. With a diameter of 17 mm, this brings a good degree of rigidity to the hub. High-quality, double-sealed ball bearings are installed, which ensure a permanently silky smooth run. The axis play can easily be adjusted by hand from the outside. The new pre-load adjustment ring is now easier to operate.
The freewheel on the rear hub engages with four pawls, each with three teeth, in a 56-fold titanium tooth ring, in order to be able to withstand even performance-oriented riders.
The main advantages of the Straightpull hubs, in addition to the more modern design, are non-contact spokes that do not cause any unpleasant noises and spoke heads that cannot work into the spoke flange. If desired, the Straightpull hubs can also be cross-lapped.

The light, stable and beautifully finished carbon rims come from the lightweight construction specialist MCFK in Leipzig. These offer an exclusive and flawless look. With classic rim flanges, the rims are suitable for all clincher and folding tires. The construction not only makes the assembly of the tires easy, it also holds the tires securely in the rim base. Laminated spoke holes instead of conventionally drilled holes ensure extra stability and additional durability. The asymmetrical structure enables a more even spoke tension, which further increases the rigidity of a complete wheel.

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 spoke lengths required 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!
