Rotor QX2 MTB Chainring 104BCD

Rotor QX2 Chainring 104 BCD

Whether it be a pro rider on TV or a fellow local cyclist, you may have seen these ovalized chainrings at one time or another. You then probably immediately asked yourself, “What do they do?” Let us explain.

Rotor's ovalized Q-Rings vary drivetrain resistance during a pedal rotation to align with your leg’s natural strength spots and weak spots to boost your overall efficiency. In doing so, Q rings wisely utilize the strongest muscle groups to increase positive work, while picking up the slack in the weaker zones to reduce the negative work, smoothening out the rotation to a perfect spin that can shave seconds from every kilometer you pedal. This advance may seem miniscule, but in a sport where a second can be the difference between the top step of the podium and no podium at all; this type of advantage can be substantial.

Through Rotor’s Optimum Chainring Position (OCP) you have approximately 5 degrees of adjustment meaning you can micro adjust the position of your Q Rings to suit your style by simply making corrections toward both comfort and efficiency. Machined from 100% CNC T6 7075 Aluminum, this model of the mountain bike specific QX2 was designed to work with 9, 10, and 11 speed mountain cranks with a 104 bolt center diameter (BCD.)

Whether you’re a dedicated cross country racer or a versatile enduro specialist, mounting Rotor QX2 rings to your steed is a sure step toward increased endurance, explosive sprints and graceful climbing.
