Description
The QXL series is an even more extreme chain ring from Rotor compared to the Q-Rings. With a ovality of 16% these chainrings are 6% more oval than the standard Q-Rings that are ''just'''10%.
These 4 arm variant makes it possible to ride with QXL-rings on the new cranksets of Shimano. The Ultegra 6800 and Dura Ace 9000.
The following combinations are possible : 54/44, 53/38, 52/36, 46/36.
The Rotor Bolt Cover Set is not supplied! These are the black caps you can see on the third picture.
The thoughts behind Rotor
Rotor’s intention with the Q-Ring and QXL-Rings is clear: every pedal stroke has a ‘dead center’ when the cranks are in a vertical position. This is where your power output is the lowest so you want to get over that point as efficiently as possible. Rotor Q-Rings and QXL-Rings have less teeth on the chainrings so you’re past that point quicklier. It has more teeth where you have more power. This principle sees that you get over the top-dead-center efficiently so you get to your maximum power output with as much momentum as possible. Your pedal stroke has way better power distribution which improves your cadence and is less tiring for your muscles.
This technology is characterised by efficiency. Rotor believe that their products may not make you speedy as such, but that these rings improve your pedal stroke in such a way that your actual nett time is guaranteed to be faster.
Several scientific studies have proved this positive effect of Rotor Q-Rings / QXL-Rings. Even greater evidence for this are the many victories of professionals that use the Rotor chainrings.
