R2BIKE wheelset 28" Disc GRV | Extralite Road Straightpull Center Lock hubs | Light Bicycle Carbon rims
Area of application: Gravel GRV
Road cyclists and gravel riders are always looking for the best compromise between weight, aerodynamics and stiffness. The combination of Light Bicycle Carbon rims and the lightweight Extralite hubs should therefore always be on the 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
Light Bicycle were ahead of their time with the Falcon Pro WG rims. While many manufacturers only launched gravel wheels with an inner width of 30 millimetres or more in 2024, the Chinese have had their high wide gravel rims in their range since the beginning of 2023. The advantages are obvious. Wide tires are integrated into the rim profile in a streamlined manner, making the system more aerodynamic and less susceptible to crosswinds. The large inner width also gives the tires more volume, which has a positive effect on the damping properties and provides more reserves against punctures. In addition, the tire remains stable on the rim even at extremely low air pressures and high lean angles. The hybrid hook profile on the rim flange also ensures a secure tire fit.
Despite the extreme dimensions, the WG rims in the Flyweight version weigh less than 400 grams thanks to a complex manufacturing process and are nevertheless more resistant to mechanical loads when riding.
Please note the maximum permissible rider weight of 90 kg.
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.
