With the Vegast crank arms, the specialist for high-end CNC milling technology Rotor offers a state-of-the-art and extremely variable direct mount crank system for almost every application profile in road and gravel bikes, TT and triathlon.
The Rotor Vegast crank system for racing bikes was created together with the Rotor Aldhu and shares the innovative and modular design with it. While the Aldhu was extremely trimmed to be lighter, the Vegast scores with an excellent price/performance ratio and otherwise offers all the properties of its big brother.
The crank arms of the Rotor Vegast are made of particularly high-quality, cold-forged and CNC-machined 6082 aluminum, which is hollow-milled using "Trinity Drilling".
The Rotor Vegast is delivered as a crank arm set and can be combined with a large selection of 1x and 2x DM chainrings (oval and round), direct mount spiders for 110x4 (Shimano compatible) and 110x5, the INspider power meter and various axles. All components can be replaced at any time, for example when changing bikes. Thanks to the high degree of modularity, variability and compatibility, the Rotor Vegast fits perfectly into existing groupsets from other manufacturers.
Crank and chainring assembly requires only a 10mm Allen key. This makes assembly/disassembly or a chainring change child's play. And not only with 1x systems, but is also possible with 2x DM chainrings.
Rotor manufactures its products exclusively in Europe and in its own factory in Madrid. Short delivery times, an excellent supply of spare parts and support are thus guaranteed.
