Rotor Q-Rings 5 arm MTB (Inner 74mm BCD): 5 bolt inner MTB chainrings for use with 2x 9/10 speeds systems. Rotor Q-Rings help overall endurance & performance by reducing the dead spots while riding. The oval shape allows for your legs to create a smoother & more effective pedaling stroke. How It Works: Rotor Q-Rings allow for easier moving of the legs through dead spots creating the feel of a smaller circular chainring & enabling your legs to remain in the power stroke for a longer periods of time. Q-Rings change the equivalent tooth size by decreasing it before the dead-spots & increasing it when the rider is at the pedal down stroke Utilising the OCP (Optimum Chainring Position) enables you to customize (fine tune) the position of the chainring for your personal riding habits & riding position on the bike. This ring is designed to fit the Rotors own MTB double chainsets or any other 5 bolt double chainset with 74mm BC inner ring BCD CNC machined 7075 T6 aluminium Black Anodised 9/10 speed compatible 5 bolt 74mm BCD Designed to run with the matching 40T outer ring ...

Rotor Q-Rings OCP3 (Outer): Rotor Q-Rings help overall endurance & performance by reducing the dead spots while riding. The oval shape allows for your legs to create a smoother & more effective pedaling stroke. How It Works: Rotor Q-Rings allow for easier moving of the legs through dead spots creating the feel of a smaller circular chainring & enabling your legs to remain in the power stroke for a longer periods of time. Q-Rings change the equivalent tooth size by decreasing it before the dead-spots & increasing it when the rider is at the pedal down stroke. For example a 53T Q-Ring is equivalent to a 51T around the upper dead-spot but when power is applied & the pedal goes down the equivalent chainring tooth size reaches 56T allowing for longer power strokes. Reduces heart rate, knee strain & lactic acid production Faster recovery & reduced fatigue Great for acceleration & sprints Easy to install Aluminium with a special nickel plated finish Will fit to Shimano Ultegra 6700 series standard 130mm BCD Chainsets Will also fit SRAM BB30 Standard 130mm BCD Chainsets This ring has Optimum Chainring Positioning number 3 only (OCP3) Design to run with the matching 39T inner Ring ...
