    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!

Colour Spoke Nipples

  • 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 29" XC | Ursus Straightpull 6-hole hubs | Newmen carbon rims

intended use : Cross Country XC to light Trail TR

With this wheelset, racers can also really let it rip. The robust Ursus hubs and the excellently crafted Newmen rims forgive even a driving mistake. The balanced selection of components guarantees you high reliability and a long service life.

Ursus is an Italian bicycle company based in Rosà, a small town in northern Italy. With almost 50 years of experience in development and manufacturing, they have built a comprehensive portfolio of bicycle components. All components are developed in-house, manufactured and tested on modern CNC machines, ensuring consistently high quality.
The Ursus XD51 is the right choice for anyone looking for a comparatively light and stiff hub. This is achieved by using aluminum 7075 and a 15 mm axle . By choosing large bearings with a good LLU/LLB seal and additional splash protection in front of the bearings, a long service life with minimal maintenance is achieved.
The special shape of the 6-hole mount ensures optimal distribution of the braking forces and thus leads to a more sensitive braking feeling.

Like all Newmen carbon rims, the Advanced rims are made of high-end UD fibers and impress with their first-class mechanical properties and extremely low weight. They are the ideal basis for a tough cross country wheelset.
The hookless design makes them ideal for tubeless use. The significantly reinforced rim flange can withstand potential punctures better and allows driving with little air pressure. In order to avoid weak points and increase the service life, the spoke holes were drilled using a special process. The large inner width gives even wide tires reliable support. Due to the slightly outwardly positioned sides, the shape of the tire is more rounded, which results in significantly better cornering grip and increased safety.

Wheel construction at R2-Bike

Our wheels are assembled entirely by hand by our wheel builders. During the entire construction, it is important to ensure 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 broken spokes, as long as they are not caused by violence.

The following services are also already included:

You get a universal wheel bag for all common sizes.
You will receive a replacement spoke with a nipple in all the required spoke lengths so that you can repair the wheel at short notice 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 charged.
You get a crash replacement promise: If your wheel is damaged due to force majeure, we will rebuild it once. We offer a 100% discount on all labor costs and only charge for the material.
