AEKO, a manufacturer of custom-made bikes and high quality components, presents ZIRCULUM90,
an innovative carbon rim specifically designed for lighter but stronger fat bikes. ZIRCULUM90 rim is the result of over two years of tests.
ZIRCULUM90 rimshows highmechanical strength. Each prototype has been veri fiedwith over 1000 hours of testing. Its weight is particularly low due to the choice to use carbon fiber with different thicknesses.
The insertion of additional carbon layers, at the coupling of the spokes, allows a better nipples fastening to the circumference. Different thicknesses give a higher stiffness that prevents the natural drift of the wheel.
Not least, AEKO developed ZIRCULUM90 rim with hookless profiles to give a performance advantage. The tyre is more stable and the wheel corners muchbetter.
AEKO, with the advice of engineers specialized in compositematerial design, optimized the final version of ZIRCULUM90 rim. The rim has been developed with a specific software that simulates the final product. This analysis improved the overall mechanical performance, leading to the final weight of 425 grams.
To make ZIRCULUM90 rim, AEKO chose only materials and components made in Italy and decided to cooperate with an Italian workshop, specialized in molding carbon fiber components for the automotive sector.
