Carbon as material for rims
When compared with aluminium, carbon has the decisive advantage that it hardly changes its shape. Consequently, the runner wheel is distinctly more long-lived and less susceptible to side or radial run-out.
Complex layer structure
No two carbons are ever alike. The layer structure and the orientation of the fibers are decisive for the function and stiffness of a carbon component. Our products meet all requirements on low weight, stiffness, comfort and esthetic appearance by a complex mix of woven and non-crimp fabrics.
A very important aspect of the development was the avoidance of weak points. Whereas competitor rims are made by bonding several parts, our wheel rim is laminated and cured completely in one piece. This requires a higher level of effort but it adds stability, saves weight and makes a homogeneous rim.
26,5 mm outside width
The wider the rim profile, the better the lateral stiffness of the rim. Our wide rim profile ensures outstanding stiffness levels of runner wheels in this weight category. Force transmission with no force loss– you will feel it, e.g. when riding out of the saddle.
55 mm height
The height of the rim profile decides the radial stiffness. Radial loads to which the rim is exposed on uneven ground, by bumps or bottoming are reduced by a high profile. The load on the spokes is hardly reduced, which increases the life of the structure directly. Our rims with 55mm height are the perfect compromise of stiffness, aerodynamic design and weight. Agility is retained and excellent rolling properties ensured.
3.5 mm asymmetry
3.5 mm asymmetry are responsible that the difference hub flanges, whose position to the hub centers is obviously asymmetrical, is reduced by 7 mm. The lateral spoke angle and the spoke tension on the right and the left side are adjusted by the asymmetry. Stiffness and life profit from this geometrical intervention.
18 mm inside width
Ideal for racing tires and cross tires with a width between 23 and 35mm. Hooks laminated in the inside flank efficiently prevent the tire from coming off the rim at high pressures or in tubeless application.
Laminated spoke holes
Another important advantage of our rims is the pre-compressed laminated spoke holes, which are not drilled – this means no fibers are cut through, which adds even more stability to the runner wheels. Besides, it protects the rim from spoke strip.
Preformed ball-head nipple seats
To ensure a perfect fit on the nipples in the rim you need the right nipple seat. The nipple seats in our rims are preformed, compressed and adapted specifically to the nipple geometry of Sapim and DT Swiss nipples.
For tubeless tires
The advantages of the tubeless technology can now been exploited to the full. Lower inflation pressure provides better grip, traction, comfort and riding pleasure. The rolling resistance is reduced and propulsion guaranteed. Our rim base is suitable for tubeless ties of all common makes.
Integrated valve design
A special design at the valve seat makes the valve head “disappear“. This technology has been developed specially for the application with tubeless tires. This makes mounting the tire with pre-installed valve a lot easier. Even non-tubeless tires are easier to fit.
By dismissing the brake flanks we are moving with the times. The future of deceleration in cycle racing and cross-country events belongs to the disc brake. No heat is transferred, for example, on long, steep downhill tracks – safety profits. Scraping noise and reduced braking in rain and muddy ground are things of the past. The rim does not wear and you can enjoy it for a long time.
