Wheelset 28 "Disc RR | Newmen Road Straightpull Center Lock hubs | Alchemist carbon rims
intended use : Racing bike RR, Gravel GRV
Racing cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Alchemist carbon rims and the indestructible Newmen hubs should therefore always be on the shortlist. The balanced selection of components guarantees you a high level of reliability and a long service life.
Hubs
The Newmen FADE hubs will also find many fans again. Here, too, you do not need to worry about setting the axial bearing play. The durable, double-sealed industrial bearings are precisely and tension-free ex works. A high degree of user-friendliness has been gained through this further development. You can better spend the saved time on your favorite trail.
The construction of the freewheel is completely different from the previous model. The goal was a low level of noise. The result was the FADE pawl system. Thereby 3 pawls engage in a new type of tooth profile. To increase durability, the diameter was increased and the individual pawls were made short and wide. In this way, the resulting forces are distributed over a larger area.
Despite the relatively low weight, no savings were made in terms of security. It is better to build in a little more material at critical points, like. For example, at the transition between the brake disc and spoke mounts, as risking a defect.
rims
Alchemist Race Zirconium carbon rims are made in Italy. Toray UD carbon fibers are used as the starting material. These are held in shape by a break-proof nanopolymer synthetic resin, which is also used in Formula 1 cockpits, and thus result in a resilient carbon rim with increased impact resistance. Technical details such as reinforced spoke holes, hybrid rim flanges and an asymmetrical profile leave no potential unused. The low weight, coupled with rigidity, offers unmatched reactivity and accuracy at high speeds and changes of direction.
Please note the maximum permissible system weight in the selection menu for the rim under "Display description".
Wheel construction at R2-Bike
Our wheels are completely assembled by hand by our wheel builders. During the entire construction process, it is important that not only the concentricity is correct, but also that the spoke tension is as even as possible. The special care allows us to give a lifelong guarantee against broken spokes, as long as this was not caused by force!
You will also receive the following services for our balance bikes:
A universal impeller bag for all common sizes.
A spare spoke + nipple in all spoke lengths required to be able to repair the wheel at short notice even after an accident.
A free initial inspection of the impeller, during which the resulting work is completely free! Only shipping costs are charged.
A crash replacement promise. If your wheel is damaged due to force majeure, we will rebuild your wheel once. We grant a 100% discount on all labor costs and only charge the material!
