    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 29" XC | Berg MTB straightpull 6-hole hubs | Duke carbon rims

intended use : Cross Country XC

XC racers always want to win and are therefore looking for light yet stable wheels. The combination of Duke carbon rims and Berg hubs should therefore always be shortlisted. The balanced selection of components guarantees you high reliability and a long service life.

With a total weight of just under 300 grams, the BERG hub pair is a perfect starting point for an ultra-light XC wheelset. The aluminum hubs impress visually with their elegant straight pull design and white lasered BERG logo. The hubs also know how to impress with their inner values. The built-in SKF bearings ensure long durability and low frictional resistance. A toothed disc freewheel with 45 locking points per wheel revolution guarantees instant acceleration and quick response in technically demanding passages. BERG uses 6 toothed disc springs for even power transmission. In addition to the built-in XD freewheel body, a Shimano Micro Spline compatible freewheel body is optionally available. If the hubs need servicing, they can be disassembled in just a few steps without any special tools.
In order to guarantee the safety of your components, all BERG components have undergone extensive tests according to the ISO standard in Germany in addition to intensive test drives. In order to guarantee the high quality standards in the long term, the tests are repeated on different product batches.

The carbon rims from Duke from France stand for low weight and excellent workmanship. The hookless construction is ideal for using tubeless systems. The reinforced bead means that any punctures can be better tolerated without causing damage. The fairly flat and wide rims reliably support the tires in every situation, so you don't have a spongy driving experience even with little air pressure.
The asymmetrical shape enables more even spoke tension, which further increases the rigidity of the entire wheel.

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!
