Rotor Oval Crown Aero QXL 130X5 53D

GREATER OVALIZATION IMPROVES PERFORMANCE
ROTOR introduces a new member to the Q-Rings family, the QXL.
The new QXL is a Q-Ring with a higher ovalization. It has a similar shape to standard Q-Rings and ensures exceptional stability in transmission. The QXL do not replace the normal Q-Rings, rather they complement them by increasing the range of use and the different profiles of each cyclist.

IMPROVED PEDALING
Many professional cyclists who previously refused to use Q-Rings have changed their minds and have not regretted it.
These athletes have better sensations when riding off the saddle and in sprints. The QXL are efficient in conditions of maximum power and intense sustained efforts, such as in TT, sprint, climb, etc.

DESIGNED FOR CYCLISTS WHO WANT A HIGHER OVALITY
QXL crowns are perfect for "powerful" athletes with more developed muscle mass that produce a higher peak and have a higher average power.
QXL chainrings greatly improve performance during off-saddle (sprint or climb), helping more in moments of maximum effort when "dead spots" become much more critical.

WHY Q-RINGS?
Q-Rings allow you to go faster. The savings can be more than 1.6 seconds per kilometer compared to traditional gears. A round crown forces the rider to ride less efficiently, while Q-rings allow you to use your maximum power.

PERFECT PEDALING 
Q-rings increase performance by doing what round chainrings cannot: they vary the resistance of the transmission depending on how you pedal. This maximizes the use of effective zones and reduces the intensity of weak and inefficient zones (thus creating less negative work). Unexpectedly, this variation is not contrary to the concept of "perfect pedaling", indeed it is the only way to approach it.

FASTER PEDALING
Recent independent scientific research on Q-Rings has shown that during high-intensity pedaling there is an increase in performance compared to round chainrings. A sprint test showed an advantage of 1.6 seconds per KM and an average power increase of 27 W (for example, some aerodynamic wheels with 60mm profile are said to gain 1.5-1.8 sec/km and 16 W savings). In addition, oxygen consumption and heart rate were statistically lower with Q-Rings.
What does it mean when you're on your bike? Q-Rings provide such pedaling benefits that they will get you a noticeably better version of yourself. You will develop a new, deeper resistance, a newfound ability to accelerate to drive to the limit. They will help you stay with the "leading group" that usually detaches you inexorably, boost the sprint and persevere like never before.

TECHNOLOGY

OCP SYSTEM

Optimal placement of the crown:
The OCP (Optimum Chainring Position) adjustment of Q-Rings allows you to meet the needs of every cyclist.
Thanks to the OCP adjustment, a classic crown combined with Q-Rings oval crowns allows a positioning of holes of 5 degrees between the fixed positions.

Comfort in any position:
The OCP adjustment of the q-Rings allows you a comfortable ride in any position:
Sitting
