Rotor Double Chainring DM Spidering for ALDHU / VEGAST / INPower, Q-Rings

Even more customisation: the Spidering Double Chainring by Rotor

The Rotor Spidering double chainrings are made from one piece and are mounted on the axle using the Direct Mount method without tools. To change the chainrings, only a 10 mm hex tool is needed to mount/dismount the drive side crank arm. Crackling from the screw connections between spider and chainring is now a thing of the past.
Whether it's with round chainrings or the oval Q-rings from Rotor, everything is possible. For the first time, the direct mount system facilitates the fine adjustment of oval chainrings in 1-degree increments, which helps to create unique customisation options tailored to individual requirements.

Technology:

Oval Chainrings
Bio-mechanical studies show that Q-Rings provide better performance than conventional chainrings. The effect is achieved by making the largest muscle groups in the legs more effective and eliminating the dead centre when pedalling. This results in a much smoother and rounder ride overall, with less muscle fatigue. The biggest advantages of using Q-Rings are the significant improvement in general fitness due to improved pedalling, greater sprinting ability due to the elimination of dead centre, slower muscle fatigue, and ultimately an increase in cardiovascular endurance for athletes.
A submaximal test followed by a time trial over a distance of 1 km proved that the Q-rings reduce heart rate and oxygen consumption while improving performance by 1.6 seconds compared to round chainrings.

OCP Mount
The exclusive Rotor technology OCP Mount stands for biomechanical optimisation of the pedal stroke when using Q-Rings. OCP Mount allows you to adjust the alignment of the chainring on the crank in 1 degree increments. The shape of the axle allows independent positioning of the crank arms and Spider or Direct Mount chainring, changing the relative position so that the optimum setting can be found for the user.
The multiple positioning possibilities of OCP Mount allow a super fine adjustment of the OCP (Optimum Chainring Position). This makes it possible to prevent or eliminate knee problems, to optimise the effectiveness of the crank rotation or to improve the traction on the MTB and cyclocross.
Position your chainrings with Rotor's OCP Mount System to get the most out of your ride.
