Rotor Aldhu Q-ring R8000 / R9100 Drev

The Rotor Aldhu Q-ring R8000 / R9100 front blade is suitable for Shimano Dura Ace R9100, the Ultegra R8000 and Rotor ALDHU 3D+ crank sets. These chainrings are CNC milled so you get a very nice and lightweight chainring. In combination with the Rotor Aldhu 3D + Spider you can adjust the blades in any angle, so that it is adapted to your needs. The Rotor NewQ 110*4 chainrings take the dead center out of your torque, so you'll experience more efficiency with every pedaling movement.

The thoughts behind the Rotor Q-Ring chainring are clear: each pedal movement has a 'dead center'. This is the moment when your cranks sit vertically. At this point there is no possibility to keep pressure on your crank/pedals which makes you want to get beyond this point as fast as possible. Rotor Q-Rings have less teeth on its dead center which makes you go faster past this point. The next thing that happens is that you feel maximum resistance, at this point you can get maximum power out of your rotation. With this technology you will pass your dead center faster which ensures less power loss before you point of maximum power. This results in an efficient pedal movement, and less fatigue in your muscles.

The technology behind the rotor is characterized by efficiency. Rotor believes in fact that its products are initially not so much 'faster' but it's mostly the efficient pedal movement which improves the actual net time.

Several scientific studies have proven the positive effect of Rotor Q-Rings chainRings. Perhaps even the best proof is the many victories achieved in the pro peloton on Rotor Q-Rings / QXL-Rings.
