R2BIKE wheelset 29" XC DC | Extralite MTB Straightpull 6-hole hubs | R2BIKE carbon rims
Application: Cross Country XC, Down Country DC
XC racers always want to win and are therefore looking for lightweight yet stable wheels. The combination of lightweight R2BIKE carbon rims and Extralite hubs should therefore always be on your shortlist. The well-balanced selection of components guarantees you high reliability and a long service life.
Hubs
Extralite hubs set standards in all respects. They are light, attractive, reliable and can be converted to different axle standards. The design of the hubs is optimized using modern simulation technology and the oversized shape offers an optimum flow of force in the material.
The freewheel is realized via a toothed pulley that engages directly with a toothing inserted into the freewheel. In order to transmit even the highest forces safely, all teeth always engage with each other. This not only results in a noticeably shorter freewheel travel until power is applied, but also an incomparable sound. This extremely direct power transmission offers clear advantages, especially when pedaling hard or in technically difficult terrain. The 2nd generation also has an improved seal between the hub shell and freehub and is easier to maintain. If the gearing is ever worn, it can be replaced and the function restored.
The main advantages of Straightpull hubs, apart from the modern design, are contactless spokes that do not cause any unpleasant noises and spoke heads that do not work their way into the spoke flange. However, if desired, the Straightpull hubs can also be cross-spoked.
Rims
If you don't want to compromise, here is the perfect rim for your adventures. Very light, stable and durable, there are no limits to its XC use and your opponents will only see your rear wheel. And it doesn't skimp on safety either, as it is approved for a system weight of 100 kg.
How did the developers achieve this? First and foremost, of course, the choice of material plays an important role. Not all carbon is the same. The decision was made to use high-quality T700 fibers from Toray Industries, one of the world's leading suppliers of this material. These have incredible strength, are very stiff and also weigh very little. However, high-end material alone does not make a high-quality product. It also depends on the manufacturing process, which is where the rims score points. Their sandwich construction combines different carbon layers. This enables specific, punctual reinforcements and therefore greater overall stability of the rim without increasing the weight.In addition, a carbon strip has been used in the spoke hole area to prevent the nipples from tearing out and to allow a higher spoke tension.
The unique, flawless look in an elegant matt finish is also achieved using a special resin. This allows the carbon layers to harden perfectly, prevents bubbles from forming and ensures a resistant surface. This means that even stone chips cannot harm it.
The hookless rim flange ensures the best tubeless compatibility and high puncture protection. This has been specially reinforced to distribute the forces over a larger area. This significantly reduces the likelihood of damage in the event of punctures. Lateral bruises are also much easier to absorb, so you can be forgiven for the odd riding mistake.
The rim has an asymmetrical rim profile, which enables a more even spoke angle. This optimization has a number of advantages. The tension on both sides can be better aligned, which is beneficial to the durability of the spokes and the wheel as a whole. The normally direction-dependent lateral stiffness is also adjusted, making the wheel more stable in itself.
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.
