R2BIKE wheelset 28" Disc RR | Chris King Road Center Lock hubs | Duke Carbon rims
Application: Road bike RR, Gravel GRV, Time trial
Road cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Duke carbon rims and the indestructible Chris King hubs should therefore always be on your shortlist. The balanced selection of components guarantees you high reliability and a long service life.
Hubs
When the engineers at Chris King started developing the R45, everything was created under the motto "light & fast". Every detail was fine-tuned and the result is something to be proud of. Not only is it lighter than its predecessor, it is also considerably stiffer thanks to the 17 mm axle. As a result, it twists less and transmits steering commands very precisely. But one thing has remained the same: the soul of Chris King.
Thanks to the enlarged hub flange, shorter spokes can be used in wheel construction, which not only saves weight but also makes for a very stable and durable wheel.
At the heart of the hub are the ball bearings. These are also developed and produced directly at Chris King. This means they can be fully adapted to the specific loads and forces. Thanks to the multiple seals, the ingress of water or dirt is virtually impossible. Adjusting the bearing play is very simple and can also be carried out when the wheel is installed.
The unmistakable sound of the freewheel is the trademark of the rear wheel hubs. It is generated by the 45 grid points of the stainless steel toothed pulley. Thanks to this 3-piece ring drive system, every pedal stroke is immediately converted into propulsion without much idle travel.
These unique features are still part of the hubs in the 4th generation, but the inner workings have been fundamentally improved in terms of maintenance and service. Thanks to universal and versatile axle components, conversion to other hub or freehub standards has become much more cost-effective. The use of common bearing sizes guarantees better compatibility with each other. The disassembly and assembly of the hub has also been significantly simplified and the preload can be adjusted more precisely.
Rims
The carbon rims from Duke in France stand for outstanding workmanship and low weight. Thanks to the SLR2 manufacturing technology developed by Duke, the latter has been reduced by approx. 10% compared to other rims, while at the same time increasing durability and stability. The use of highly modular carbon fibers also improves the inherent damping, which benefits increased riding comfort. The modified structure also allows the unrestricted use of modern tubeless tires.
Please note the maximum permissible system weight in the rim selection menu under "Show description".
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 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 get a crash replacement promise: If your wheel is damaged due to force majeure within 2 years of purchase, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
