    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 | Syntace Road Straightpull Center Lock hubs | Duke Gravel Carbon rims

intended use : Gravel GRV

This light yet stable wheel set is the first choice for dedicated gravel or cross bikers. The balanced selection of components guarantees you high reliability and a long service life.

The heart of these wheelsets are the Syntace hubs. These combine the finest turning and milling skills, are simple in appearance, but have superior inner values.
The hub body is equipped with stable precision deep groove ball bearings, which have a special grease filling for perfect protection against corrosion and outstanding durability. The 17 mm oversize axle ensures maximum rigidity with minimum weight. An additional, double sealing washer in front of the ball bearing prevents the ingress of spray water. The infinitely variable MicroAdjust adjustment cap allows the axial hub play to be adjusted quickly and easily.

The carbon rims developed and manufactured by Duke for gravel use are made for tough off-road use with their large internal width and the high approved system weight. They will definitely not let you down. You have the option of driving very wide tires, which increases comfort and grip. They are also tubeless compatible, which reduces the risk of punctures.

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. The special care allows us to give a lifetime guarantee against broken spokes, as long as this is not caused by violence!

You will also receive the following services with our wheels:

A universal impeller bag for all common sizes.
A spare spoke + nipple in all required spoke lengths to be able to repair the impeller at short notice even after an accident.
A free initial check of the impeller, where 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 for the material!
