R2BIKE wheelset 28" Disc RR GRV | DT Swiss 180 Road Straightpull Center Lock hubs | R2BIKE Carbon rims
Application: Road bike RR, Gravel GRV
Road cyclists and gravel riders are always looking for the best compromise between weight, aerodynamics and stiffness. The combination of R2BIKE carbon rims and the reliable DT Swiss 180 hubs should therefore always be on the shortlist. The well-balanced selection of components guarantees you high reliability and a long service life.
Hubs
Lighter, stiffer, more precise and easier to maintain - these are the strengths of the DT Swiss 180 hubs. The smooth-running SINC Ceramic ball bearings offer you a further decisive advantage; they ensure minimal rolling resistance. The stiffness of 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 RATCHET EXP toothed disc freewheel has also been further developed. This highly reliable system ensures direct power transmission without losses.
The main advantages of Straightpull hubs, apart from the modern design, are contactless spokes that do not cause any unpleasant noises and spoke heads that cannot work their way into the spoke flange. However, if desired, the straightpull hubs can also be cross-spoked.
Rims
Perfectly finished, light and yet sufficiently stiff are the most important specifications of the R2BIKE rims. Depending on the rim height, you can conquer summits or set a good pace on the flat. And they have not skimped on safety either, as they are approved for a system weight of 90 kg.
How did the developers achieve this? First and foremost, of course, the choice of material plays an important role. Not all carbon is the same. The decision was made to use the high-quality T800 fibers from Toray Industries, one of the world's leading suppliers of this material. These have incredible strength, are very stiff and yet are among the lightest on the market. However, high-end material alone does not make a high-quality product. It also depends on the manufacturing process, which is where the rims score points. Their sandwich construction combines different carbon layers. This enables specific, punctual reinforcements and therefore greater overall stability of the rim without increasing the weight.In addition, a carbon strip was used in the spoke hole area to prevent the nipples from tearing out and to allow higher spoke tension.
The unique, flawless look in an elegant matt finish is also achieved using a special resin. This allows the carbon layers to harden perfectly, prevents bubbles from forming and ensures a resistant surface. This means that even stone chips cannot harm it.
The rim flank has a classic hook for secure tire guidance. This prevents the tire from bouncing even at high air pressures and you always have your bike under control. Of course, the rims can also be ridden tubeless.
They also have an asymmetrical profile, which allows a more even spoke angle. This optimization has a number of advantages. The 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 in itself.
Wheel construction at R2BIKE
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 is not caused by force.
The following services are also included for first-time buyers:
You will receive a universal wheel bag for all common sizes.
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, where the resulting work is completely free of charge. Only shipping costs apply.
You receive 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.
