Q RINGS QARBON BCD110x5 Q53AT(38) OUTER

Your bike´s aesthetics matter and, to maintain its sleek, elegant look, we´ve bonded a 3K woven, high-modulus carbon sheet to the outside of a Q ring to reinforce the Q ring´s structure. Carbon fiber´s structural properties allow for a more aggressively-machined aluminum section in comparison with a conventional aluminum chainring. 8% lighter with 20% increased stiffness, Q rings Qarbon give you all the benefits of Q rings but with carbon fiber accents to both reduce weight and distinguish your bike as a performance machine inline with your sophisticated tastes.

TECHNOLOGIES:
- AERO:
Allied against the wind
ROTOR Aero components, such as Aero chainrings or the flagship aero FLOW crank, help cyclists maximize their wattage output in the war against wind resistance.
Tapered FLOW crank arms optimize aero behavior, while a smooth, solid aero chainring surface reduces aerodynamic drag.

-ALU 7075:
Why we choose aluminum
7075 aeronautic-grade aluminum alloy offers superior physical properties with which to craft components like our signature Q-Rings, REX 3 and 3D24 cranks.

-ALU CNC
Manufactured with the latest technology

Computer Numerical Control (CNC) machining provides a precise and consistent manufacturing process. This is especially important when it comes to crafting bike components in order to ensure flawless funcionality with respect to all the parts working together. Equipped with the latest CNC resources, ROTOR parts are precisely machined to within a hundredth of a millimeter.

- Optimum chainring angle:
Get to know your best effort
OCA stands for Optimum Chainring Angle and is one of the proprietary metrics offered by ROTOR INpower and 2INpower. OCA is closely linked to ROTOR Q rings, as it helps to find the proper chainring setup.
OCA determines the angle in degrees, measured from the upper dead spot (with the cranks perpendicular to the floor) in which the effort barycenter (area enclosed by the torque/force curve) is shown in the TORQUE 360 graph.

- Optimum chainring position:
Only possible with Q rings
Optimum Chainring Position (OCP) represents the different setup positions that ROTOR Q rings offer to fit a rider’s distinct pedaling style. Q rings feature up to 5 OCP´s, with OCP 3 as an intermediate starting point, all to optimize your pedaling style.
You can determine your OCP if you know your Optimum Chainring Angle (OCA), which can be found by conducting a TORQUE 360 pedal analysis via ROTOR´s 2INpower and INpower User Software.

-Qarbon:
Weight, stiffness and strength – get all three
3K woven, high-modulus carbon fiber is bonded to the outside of a Q ring to reinforce the Q ring´s structure. Carbon fiber´s properties allow for weight reduction in comparison with conventional aluminum chainrings. At the same time, the stiffer carbon fiber sheet offers increased lateral stiffness.
