Are Rotor Q-Rings worth it?
Q-Rings do not eliminate the dead spots, but they do lighten the load for the weaker areas and transfer that load to the stronger muscles.” “With Q-Rings the pedal stroke remains circular. It is only the rings that are elliptical. This is one reason why the system is an excellent one for trained athletes.

What are Osymetric chainrings?
The shape of the Osymetric rings attempts to concentrate your pedaling power where your force is at a maximum, while effectively reducing the load where your power input is at a minimum. This decreased chainring radius helps you go faster through the dead spot.
How do you calibrate a rotor power meter?
Push “Calibrate” without any weight on your pedals. The calibration value should show “1000.” After you see 1000 appear on the screen slowly turn the crank counterclockwise two or three turns and place it in a 6 o’clock vertical position again. Push “Calibrate” again and record the offset value shown in the monitor.
Can I change front chainring?
Replacing the Chainring In some crankset styles, the chainring bolts face outside instead and require a tool like a nut wrench tool to hold it in place from behind while you use a hex or Torx wrench to remove it from the front. Again, the bolts may take a bit of force and leverage to remove.
