R2BIKE Wheelset 29" XC | Extralite MTB Straightpull 6-hole hubs | Porte Carbon rims
Application: Cross Country XC
XC racers always want to win and are therefore looking for lightweight yet stable wheels. The combination of high-quality Porte 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 integrated 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
The PORTE Rathe rims play in the absolute top league of lightweight rims for XC racing. Their combination of an above-average inner width of 30 millimeters and very low weight is record-breaking. In practice, this results in an extremely easy to accelerate rim and a very stable running tire, even at very low air pressures. In addition, the large inner width allows tires up to 2.7" wide to be used. The tubeless inner profile ensures a secure fit of the tire on the hookless rim. The low weight of the handmade rims was achieved thanks to the relatively low profile height of just 21 millimetres. The asymmetrical spoke holes with an offset of 2 millimetres provide the necessary rigidity in the wheel. A reinforced rim bed provides secure support for the spoke nipples and makes the wheels more stable.
In order to guarantee the safety of their components, all BERG components have undergone extensive tests according to ISO standards in Germany in addition to intensive test rides. In order to guarantee the high quality standards in the long term, the tests are repeated for different product batches.
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 offer a lifetime guarantee against spoke breakage as long as it is not caused by force.
The following services are also included:
You will receive a universal wheel bag for all common sizes.
You will receive a replacement spoke with nipple in all required spoke lengths so that you can repair the wheel quickly after an accident.
You will receive a free initial inspection of the wheel, where 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, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
