Wheelset 28 "Disc RR | Carbon-Ti Road Straightpull Center Lock hubs | Duke Carbon rims
intended use : Racing bike RR, Gravel GRV
Racing cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Duke Carbon rims and Carbon-Ti hubs should therefore always be on the shortlist. The balanced selection of components guarantees you a high level of reliability and a long service life.
The bodies of the X-Hub SP hubs are elaborately CNC-milled and rotate around a multi-butted aluminum axis. With a diameter of 17 mm, this brings a good degree of rigidity to the hub. High-quality, double-sealed ball bearings are installed, which ensure a permanently silky smooth run. The axis play can easily be adjusted by hand from the outside. The new pre-load adjustment ring is now easier to operate.
The freewheel on the rear hub engages with four pawls, each with three teeth, in a 56-fold titanium tooth ring, in order to be able to withstand even performance-oriented riders.
The main advantages of the Straightpull hubs, in addition to the more modern design, are non-contact spokes that do not cause any unpleasant noises and spoke heads that cannot work into the spoke flange.
The carbon rims from Duke from France stand for excellent workmanship and low weight. Thanks to the SLS2 manufacturing technology developed by Duke, the latter was able to be 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 self-damping, which benefits increased driving comfort. The modified structure also enables the unrestricted use of modern tubeless tires.
Wheel construction at R2-Bike
Our wheels are completely assembled by hand by our wheel builders. During the entire construction process, it is important that not only the concentricity is correct, but also that the spoke tension is as even as possible. The special care allows us to give a lifelong guarantee against broken spokes, as long as this was not caused by force!
You will also receive the following services for our balance bikes:
A universal impeller bag for all common sizes.
A spare spoke + nipple in all spoke lengths required to be able to repair the wheel at short notice even after an accident.
A free initial inspection of the impeller, during which the resulting work is completely free! Only shipping costs are charged.
A crash replacement promise. If your wheel is damaged due to force majeure, we will rebuild your wheel once. We grant a 100% discount on all labor costs and only charge the material!
