R2BIKE Wheelset 28" Disc GRV | Carbon-Ti Road Straightpull 6-hole hubs | Duke Gravel Carbon rims
Application: Gravel GRV
This lightweight yet stable wheelset is the first choice for dedicated gravel or cross bikers. The well-balanced selection of components guarantees high reliability and a long service life.
Hubs
The bodies of the X-Hub SP hubs are elaborately CNC-milled and rotate around a multi-butted aluminum axle. With a diameter of 17 mm, this provides the hub with a high level of rigidity. High-quality, double-sealed ball bearings are used, which ensure a permanently silky-smooth running. The axle play can be easily adjusted by hand from the outside. The new pre-load adjustment ring is now easier to operate.
The freewheel on the rear hub engages via four pawls, each with three teeth, in a 56-fold titanium ring gear to withstand even the most powerful riders.
The main advantages of the Straightpull hubs, apart from the modern design, are contactless spokes that do not cause any unpleasant noises and spoke heads that cannot work their way into the spoke flange. However, if desired, the straightpull hubs can also be cross-spoked.
Rims
The carbon rims for Gravel use, developed and manufactured by Duke itself, are made for tough off-road use with their large rim width and high permitted system weight. They are guaranteed not to let you down. You have the option of riding very wide tires, which increases comfort and grip. They are also tubeless-compatible and therefore reduce the risk of punctures.
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.
