R2BIKE wheelset 28" Disc RR | Zipp Road Center Lock hubs | Duke Carbon rims
Application: Road bike RR
Road cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Duke carbon rims and the exceptional Zipp hubs should therefore always be on your shortlist. The fine selection of components guarantees you a high level of reliability and a place on the winner's podium.
Hubs
With the Zipp ZR1 SL, Zipp brings a lightweight hub set with maximum performance to the market. Based on the proven ZR1 hubs, the SL versions have a lighter hub shell and an optimized bearing system. Originally developed for the premium NSW wheels, the hubs are now also available separately.
The sophisticated freehub system offers 66 engagement points per wheel rotation and ensures fast power engagement with six offset pawls, which are organized in two groups of three pawls each. This means that three pawls always engage simultaneously, ensuring direct power transmission from the pedal to the wheel. Another clever detail: when the hub is dismantled, the pawls remain fixed, which makes maintenance much easier.
Equipped with high-quality ceramic hybrid ball bearings, the hubs have extremely low frictional resistance. For easy maintenance, the ZR1 SL hubs come with classic hub flanges for J-bend spokes, which are still the most common spoke shape today. The hubs can be installed on e-road bikes and e-gravel bikes with motors with a torque of up to 60 Nm.
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 around 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 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 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.
