With the rotor aldhu 3D+ rotor has developed a forward-looking racing wheel crank system, which can be freely configured and mounted without special tools and expertise. The exchange of leaves is a matter of minutes thanks to the Direct Mount system when using the combination chain blade in a one-piece design or with simple blades with Direct Mount Spider. One Allen key is enough. Whether with round chain rings or the oval Q rings from rotor, everything is possible and available in many variants. The Direct Mount System The aldhu 3D+ allows for the first time the fine adjustment oval chain rings in 1 degree increments and thus an incomparable individualisation to the personal requirements. In the configuration of the aldhu 3D+, several are available from a block milled (one-piece design), chain blade combinations and press the system weight under the magic 600 gram mark. Alternatively, the crank can also be configured with a light Direct Mount Spider and two individual chain blades. The chain rings are mounted on the spider of the aldu 3D+ and are mounted on the axle without tools using this direct mount process. To change the chain rings, only a 10-hex key is required to assemble/dismantle the crank arm of the drive side. The rivalry of the chain rings is 12.5 %. The chain rings can also be mounted on Shimano 4 arm cranks in the OCP3 position, which is used by most drivers. For optical reasons, we recommend the appropriate rotor cover when used on Shimano.
