    The wing spoke made of cold drawn Sweden steel has an elliptical shape which takes advantage of the flat, light and aerodynamically more favorable but weak aero spoke and the stronger but less aerodynamic and heavy classic round spoke. This gives it the diameter necessary for torque transmission and at the same time favorable and superior aerodynamic properties with low weight!

  • The nipples are made of brass in order to achieve the best possible and long-lasting result in terms of color. The robust material is insensitive to corrosion and does not stick to the thread of your spokes, so that re-centering is still possible without any problems even after years of use. In addition, they are neither attacked nor damaged by any sealing milk that may have got into the rim well.

Wheelset 28 "Disc RR | Syntace Road Straightpull Center Lock hubs | Alchemist carbon rims

intended use : racing bike RR

Racing cyclists are looking for the best compromise between weight, aerodynamics and stiffness. The combination of Alchemist carbon rims and Syntace 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.

The heart of these wheelsets are the Syntace hubs. These combine the finest turning and milling art, are simple in their optical appearance, but with superior inner values.
The hub body is equipped with stable precision deep groove ball bearings, which have a special grease filling for perfect corrosion protection and outstanding durability. The 17 mm oversize axle ensures maximum rigidity with minimum weight. An additional, double sealing washer in front of the ball bearing prevents the ingress of splash water. The infinitely adjustable MicroAdjust adjustment cap enables quick and easy adjustment of the axial hub play.

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!
