R2BIKE wheelset 28" Disc RR | NONPLUS Components Road Straightpull Center Lock hubs | Duke Carbon rims
Range of use: Road bike RR, Gravel GRV, Time trial
Road cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Duke carbon rims and lightweight NONPLUS hubs should therefore always be on your shortlist. The balanced selection of components guarantees you high reliability and a long service life.
Hubs
After the NON+ MTB hubs made a name for themselves among lightweight builders worldwide, the decision was made to transfer their unique technical properties to an ultra-lightweight pair of hubs with center-lock brake disc mounts for road and gravel use.With their slim hub bodies for straight-pull spokes, the NON+ Road hubs fit perfectly into the overall look of modern road bikes. Their matt black anodized finish not only looks good, it also protects the hub bodies from corrosion.
Two large bearings support the hub body on a 17 mm axle, two further bearings support the freewheel and the micro-gap end caps keep dirt and water away from the inside of the hub. On the opposite side, the patented freehub mechanism is concealed inside. The unique bevel gearing has a contact surface that is approx. 400 % larger than that of conventional spur gears and therefore enables maximum power transmission with minimum wear. Together with the hard anodized surface, the special, very elaborately manufactured back of the tooth ensures low abrasion and thus additionally increases the service life. The 45-fold toothing results in a maximum free travel of 8°. This means you have immediate propulsion when you need it in difficult passages, for example, and don't lose any valuable time when sprinting to the finish.
The pair of hubs weighs in at just 211 grams, putting them on a par with the lightest hubs on the market. Despite their extremely low weight, the hubs are approved for a system weight of up to 120 kg in road bike use.
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 approx. 10% compared to other rims, 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 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.
