Rotor SRAM AXS 2X Chainring, 4-Arm, Q-Ring, 110 mm BCD, Spider Mount

The 2x SRAM AXS 110x4 Spider Mount Q-Ring chainring by Rotor - expert level

The oval Rotor 2x SRAM AXS 4-arm chainring Spider Mount with 110 mm bolt circle diameter is crafted with a high level of expertise for your AXS derailleur. It can be mounted on Rotor ALDHU, VEGAST and other cranks if you use a suitable spider (e.g. INSpider power meter). The chainring is CNC-milled from ultra-light aluminium and improves shifting efficiency thanks to an optimised tooth profile. OCP Mount technology provides almost unlimited adjustment possibilities.

Technology:

Aluminium CNC
Computer Numerical Control (CNC) milling ensures a precise and uniform production process. This is particularly important when manufacturing components that must function properly and work in congruity with other parts. Thanks to state-of-the-art CNC equipment, Rotor parts are manufactured with extreme precision, down to a hundredth of a millimetre.

Oval Chainrings
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.
