R2BIKE wheelset 28" Disc RR | Extralite Road Straightpull 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 exclusive Extralite hubs should therefore always be on your shortlist. The balanced component mix guarantees you high reliability and a long service life.
Hubs
It has long been known that the Italians around Extralite create small CNC works of art. Their extravagant design stands out from the crowd and is an eye-catcher on any bike.
They have once again outdone themselves with the next evolutionary stage of the Cyberhubs. The one-piece hub body is CNC-milled from high-strength 7075TX aluminum at great expense. This rotates around a stable 17 mm aluminum axle with double-sealed deep groove ball bearings. The axial play can also be finely adjusted in future using the micro-tuner.
The spoke mounts have been changed slightly. These are now closer to the hub body, but still use the straight-pull version to minimize susceptibility to punctures. The holes have been enlarged and rounded to a diameter of 2.8 mm and can accommodate conventional stainless steel spokes as well as carbon or even textile fiber versions. This means you are already equipped for the future. In addition, the coordinated geometry of the hub flange ensures an optimum spoke angle and can also withstand high spoke tensions. This guarantees you a very stiff and durable wheel.
A pawl freewheel provides propulsion. Two pawls engage in a titanium ring with 32 ratchets. This reduces the free travel and also reduces wear.
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 previous models, 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.
