R2BIKE wheelset 28" Disc GRV | DT Swiss 350 | Duke Baccara WRX 48 SLR2 Carbon | Sapim CX-Ray

Application: 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 350 hubs should therefore always be on your shortlist. The balanced selection of components guarantees you high reliability and a long service life.

DT Swiss 350 Straightpull hubs
DT Swiss hubs stand for simple construction and maximum reliability. Thanks to the use of elaborate seals and bearing sizes adapted to the loads, the hubs do not require any adjustment of the bearing play. This means that the rider does not have to worry about the function of the hubs for years! Should a service be necessary after tens of thousands of kilometers, the hubs can be disassembled and serviced within a few minutes without special tools thanks to the DT Swiss plug-in system.
Thanks to their simple but well thought-out design, the current 350 hubs are significantly lighter than the previous versions. The proven ratchet freehub system of the DT-Swiss 240 hubs makes the hubs an extremely reliable companion. Compared to pawl systems, the ratchet freehub offers a more even power transmission, which significantly reduces wear. With 36 teeth, the hub reacts very directly to acceleration. The new shape of the end caps makes disassembly even easier, making it even easier to convert to other axle standards.

Duke Baccara WRX 48 SLR2 UD-Carbon rims
Can it be a little wider? With an inner width of 28 mm, the Duke WRX 48 rim offers you the option of riding wide gravel tires with extremely low air pressures without the tire becoming unstable in fast corners. This provides you with excellent damping on rough gravel and off-road terrain and thus ensures more comfort and less fatigue on long distances. The tread height of 48 mm contributes to excellent aerodynamics without overdoing it with the weight. This allows you to pick up speed in fast sections and still be very agile on the trail.
The hook profile of the rims ensures a secure fit of the tire. The lower weight is achieved by optimizing the use of materials. Particularly stressed areas have been reinforced, while uncritical areas have been spared. In addition, the amount of resin used has been further reduced without sacrificing stability.
Thanks to the SLR2 production technology developed by Duke, it is no longer necessary 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. Despite the flat shape, 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.
