Rotor Chainring QX1 MTB, 4-arm, Q-Rings, 76 mm BCD
Item number: 37796
Oval chainrings that have already become XCM world champions with Christoph Sauser.
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
Optimum Chainring Position (OCP) indicates the various adjustments that Rotor Q-Rings offer to adapt to the rider's specific pedalling characteristics. Q-Rings have up to 5 OCPs (Road) or up to 3 OCPs (MTB). These positions help to optimise your pedalling behaviour.
You can determine your OCP if you know your optimal chainring angle (OCA), which you can determine by a Torque 360 step analysis with the user software of Rotor 2INPower and INPower.
