ROTOR Round Q 110 BCD Outer chainring 37T

Q RINGS BCD110x4 Q53T(39) OUTER BLACK You turn on to the road that rolls out ahead of you and tuck in for an adventure that may last hours. Every muscle movement has been trained to leave it all on the road; nothing gets wasted in this deliberate harmony between drivetrain and forward momentum. We created Q rings 110BCD for your compact cranks based on the concept that you could pedal more efficiently if you could only take greater advantage of your maximum power effort while lessening the time spent in the dead spots of a pedal rotation. Q rings´ subtle but efficient 10% ovality combined with an unprecedented orientation factor yield an improved pedal stroke marked by performance. Choose from 5 Optimum Chainring Positions (OCP) to fine-tune your improved riding experience and go further and faster with less fatigue. Weight: 148g per set 50/34 Sizes: Outer - 53 Characteristics: - 100% CNC-machined, 7075-T6 aluminum alloy - Steel shifting pins - 5 OCP points (4 points in 50/34) - Designed to work with all 9, 10 and 11 speed groupsets - Some cranks require specific Q rings Technologies: 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 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.
