R2BIKE wheelset 28" Disc RR GRV | DT Swiss 240 | Duke Baccara RX 42 SLR2 | Sapim CX-Ray

Range of use: Road bike RR, Gravel GRV

Gravel and all-road riders are looking for the best compromise between weight, comfort and durability. The combination of Duke Carbon rims and the indestructible DT Swiss 240 hubs should therefore always be on the shortlist. The balanced selection of components guarantees you high reliability and a long service life.

DT Swiss 240 EXP hubs
Lighter, stiffer, more precise and easier to maintain - these are the strengths of the new DT Swiss 240 hubs. These properties have been achieved thanks to the Ratchet EXP technology. This not only means that the hubs have fewer components and therefore lower weight and less wear, it also allows the bearing to be positioned much further out on the drive side. The greater distance between the bearings results in greater hub rigidity, lower bearing loads and therefore greater durability. The stiffness on the hub body serves to distribute the load more evenly on the spokes. Drive and braking forces are transmitted even better from both spoke flanges to all spokes. One-sided load peaks are prevented, which protects the hub, spokes and rim. The super reliable toothed pulley freehub system with its large contact surface and 36 engagement points ensures extremely direct and reliable power transmission.

Duke Baccara RX 42 SLR2 carbon rims
With the RX rims, Duke is launching an extremely versatile rim series on the market. The lightweight and robust carbon rims with an inner width of 25 millimetres cut a fine figure on road bikes as well as all-road and gravel bikes. They can best demonstrate their aerodynamic properties with 29 - 30 millimeter wide tires. But they also provide sufficient support for wide gravel tires and up to 2.4" wide tires on beach racers thanks to their large inner width. The hook profile of the rims ensures a secure fit of the tires.The low weight is achieved by optimizing the use of materials, reinforcing particularly stressed areas and saving material in uncritical areas. In addition, the amount of resin used has been further reduced without sacrificing stability.
Thanks to the SLR2 production technology developed by Duke, there is no need to rework or paint the rims during the production process. This alone can save up to 10% in weight and achieve a very high surface quality. The use of highly modular carbon fibers also improves the inherent damping, which is particularly beneficial for riding comfort.
The rims are definitely top of the class in terms of load capacity. With a maximum system weight of 125 kg, you can take a little more luggage with you.
The rims have an asymmetrical rim profile, which enables a more even spoke angle. This optimization of the spoke angle has a number of advantages. The spoke tension on both sides can be better aligned, which is beneficial to the durability of the spokes and the wheel as a whole. The normally direction-dependent lateral stiffness is also adjusted, making the wheel more stable.

SAPIM CX-Ray spokes
With the CX-Ray, Sapim has succeeded in developing an exceptional spoke. In addition to its low weight, it has an exceptional load capacity and flexibility. This also results in a wide range of applications. Whether road cyclists or mountain bikers, everyone benefits from these positive characteristics. In addition, the flattened middle section ensures excellent aerodynamics. The high material quality enables the construction of stable wheels and guarantees a long service life.
Sapim's CX-Ray spokes can be installed in all standard hub holes.

Wheel construction at R2-Bike

Our wheels are assembled entirely by hand by our wheel builders. During the entire assembly process, great importance is attached to ensuring that not only the concentricity is correct, but also that the spoke tension is as even as possible. This special care allows us to give the first owner a lifetime guarantee against spoke breakage, as long as it was not caused by force.

The following services are also included for first-time buyers:

You get a universal wheel bag for all common sizes included.
You will receive a spare spoke with nipple in all required spoke lengths so that you can repair the wheel quickly after an accident.
Within 2 years of purchase, you will receive a free initial inspection of the wheel, during which the resulting work is completely free of charge. Only shipping costs are incurred.
You get a crash replacement promise: If your wheel is damaged within 2 years of purchase due to force majeure, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
