ROTOR Q-Rings 110 BCD Oval Chainring | Enhanced Performance & Efficiency
Elevate your cycling performance and experience a revolutionary improvement in your pedal stroke with the ROTOR Q-Rings 110 BCD oval chainring. Engineered to work in harmony with your body´s natural biomechanics, these chainrings are designed for cyclists who demand maximum efficiency, increased power output, and reduced fatigue on every ride. Whether you´re a competitive road racer, a gravel adventurer, or a dedicated MTB enthusiast, Q-Rings offer a tangible advantage that you can feel from the very first pedal stroke.
The core principle of the Q-Ring is its intelligent oval design. Unlike traditional round chainrings, the oval shape effectively minimizes the intensity of the “dead spot” in your pedaling rotation—the point where your cranks are vertical and power transfer is at its lowest. By subtly changing the gear ratio throughout the pedal stroke, the Q-Ring maximizes the power you produce during the most productive phase (the downstroke) and helps you glide through the dead spot with greater ease. This results in a noticeably smoother, more consistent power delivery to the rear wheel, which can translate into faster acceleration, improved climbing ability, and better traction on technical terrain.
Many riders report a significant reduction in knee strain and overall leg fatigue after switching to Q-Rings. By smoothing out the peak torque loads on your joints, these chainrings promote a healthier and more sustainable pedaling motion, allowing you to ride longer and recover faster.
Unmatched Versatility and Fine-Tuning
These specific ROTOR Q-Ring chainrings are engineered for the acclaimed Aldhu modular crank system and modern Shimano cranks, offering exceptional integration and performance. They are available in two primary versions to suit your setup: one that bolts directly to the Aldhu 110×4 BCD spider, and another designed for Shimano-compatible 110×4 cranks, including the popular Dura-Ace 9100 and Ultegra R8000 series.
This versatility extends to ROTOR´s groundbreaking OCP (Optimal Chainring Position) Mount technology. When you combine these Q-Rings with a ROTOR Aldhu spider, you unlock the full potential of adjustability. This allows you to meticulously dial in the chainring´s orientation through five different OCP settings (1-5), personalizing the ovality to your unique pedaling style for truly optimized performance.
For those using a Shimano or Shimano-compatible spider, the chainring comes conveniently set to OCP 3. This position is the result of extensive biomechanical research and is the most commonly used and universally beneficial OCP, proving effective for over 90% of all riders. It provides an immediate and significant performance upgrade right out of the box.
