R2BIKE wheelset 28" Disc GRV | DT Swiss 180 Road Straightpull Center Lock hubs | Duke Gravel Carbon rims
Application: Gravel GRV
This lightweight yet stable wheelset is the first choice for dedicated gravel or cross bikers. The well-balanced selection of components guarantees 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
With the Duke Baccara RX and WRX rims, you get even more choice of ultra-light carbon rims for your gravel bike. Five different rim heights from 27 to 56 millimetres give you all the options you need to choose between aerodynamic properties and low weight.The large inner widths of 25 mm (RX version) and 28 / 29 mm (WRX version) give wide gravel tires very good support at low air pressures. The hook profile of the rims ensures a secure fit of the tire. The low weight is achieved by optimizing the use of materials. Particularly stressed areas are reinforced, while material is saved 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 120 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.
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.
