Description

Description

Rotor Road Inner Q-Rings are designed to capitalize on the strongest part of your pedal stroke and minimize the negative effects of the weak portion known as "dead spots." The Q-Rings have a subtle oval shape and, with multiple mounting holes, can be "clocked" to maximize the effects of your biomechanics, pedaling style, and bike geometry. And aside from those benefits, the shift pins and ramps on the Q-Rings have been redesigned to provide faster shifting.

The Q-Ring's oval shaping smoothes the pedal stroke through the dead spots and takes advantage of your power potential at the optimum time -- in the power zone. The multiple mounting hole system is called OCP (Optimum Chainring Positioning) and it allows each rider to maximize the benefit of the Q-Rings.

The long axis of the oval chainring should be vertically aligned in the power zone when the crankarms are at or just below horizontal. This position gives the rider maximum leverage, and therefore maximum torque transmission to the rear wheel. Inversely, the short axis of the chainring is aligned so that it nears the vertical when the crankarms are also close to vertical. The short axis of the oval creates a shorter lever when you make less power. The effect is a subtle acceleration of the legs through the top and bottom of the stroke and less muscle strain at these traditionally weak points in the cycle. With Q-Rings, you'll put more power to the ground while taxing your muscles less.

Might not be a boost in your power

  • Familiarity: I've used it several times

I spent the last six weeks doing blind power testing on Q-rings, Osymmetrics and circular chainrings. There wasn't a significant difference between the circular and the q-rings. So if you are trying to increase your power, I would just hit the trainer harder. Also you are likely to experience problems shifting with these rings

very little information on your "blind test". Did you measure your heart rate whilst comparing the two? How about the effort at certain RPM's? Your review is extremely vague...just sayin'
