Rotor QX2 Outer Chainring $150.00
Eliminate dead spots.
Rotor took its road-winning technology and finally released ovalized mountain bike rings, as well as single-, double-, and triple-specific REX mountain bike cranksets this past fall. The QX2 is designed as the outer chainring for a 2-ring mountain bike drivetrain.
Ovalized chainrings are essentially designed to maximize the efficiency of your pedal stroke by prolonging the power zone and minimizing dead spots. They are machined with a subtle oval shape and, with multiple mounting holes, can be "clocked" to maximize the effects for your biomechanics, pedaling style, and bike geometry. The QX2 features an ovality of 10%, which helps you accelerate better, experience smoother torque, and grip better off road. Additionally, the alternating thick and thin tooth profile keeps your chain from dropping — even in the roughest conditions. This eliminates the need for a chain guide.
The Rotor QX2 Outer Chainring comes in sizes: 104-38t, 104-40t, 110-36t, 110-38t, 110-39t, 110-40t, 120-38t, and 120-40t. Each ring comes in the color Black.
