Rotor Corona BCD110*4 36d DM/SH 9100/8100 Black

• 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 crown positioning :The
  OCP (Optimum Chainring Position) adjustment of Q-Rings chainrings allows 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:La
  OCP adjustment of the q-Rings allows you a comfortable ride in any position:SeatedOut of saddle
  
  (uphill or sprint)
