Installing ROTOR Q-Rings

ROTOR Q-Rings are the famous oval chainrings manufactured by the Spanish company. In this article we are going to explain step by step how to install a set of ROTOR Q-Rings. These chainrings will make your pedal stroke much more effective. It can be used in road, MTB, cyclocross and triathlon bikes.

Fitting Rotor Q-Rings is quite simple. These oval chainrings for road, MTB, cyclocross and triathlon bikes can be used with almost all kind of crank arms. After some simple steps you will have them installed in your bike.

First thing you must do is to choose your Q-Rings properly. So, for road bikes there are five models, for mountain bikes are models which can be used with one, two or three chainrings, there are two models for cyclocross and if you are a triathlon enthusiast you can choose between Q-Rings TT or QXL. Downhill bike’s enthusiasts are also covered. On this link you can see the characteristic of all the oval Q-Rings chainrings for the different specialties.

Almost certainly you can use the crank arms that already have on your bike and with a little knowledge and the right tools can install them yourself in a simple way.

Remove the right crank arm to work more comfortably and then take apart the chainrings from your bike using an allen key so we can put the new ROTOR Q-Rings. Your new chainrings have different settings so you can find the perfect pedalling position. This is known as OCP or “Optimized Chainring Position”, the best way to place the chainring. We recommend trying in the position 3 and taking it from there… In the Q-Rings owner’s manual there are many examples to show you how to make these tests. First we install the bigger chainring and then the rest, assuming our bike has more than one. All of them go in the same OCP position. If necessary apply in the screws a permanent locking that you will find in hardware stores.

We will finish this part of the ROTOR Q-Rings assembly putting back the right crank arm, using a torque wrench to achieve the right tightening.

You must also place the shifter in the highest part of the ROTOR Q-Rings, that is between 1 and 3mm. Then make sure the shifter works properly switching from one chainring to the other.

Now try different settings with the OCP until you find the ideal position. Remember, when you purchase your new ROTOR Q-Rings you will find attached a lot of valuable and useful information.

Many ROTOR Q-Rings users have some doubts about whether the chain suffers or it will experience some problems due to the oval shape of the chainrings.

If you take a look at the ROTOR Q-Rings chainwheels you will see that the chain has to adapt constantly to the oval shape. The whole system has been designed to this purpose, so the chain does not jump unexpectedly, no even when shifting.

When assembling the Q-Rings chainrings we advise you to place the shifter in the highest part of the oval. This is the key to have the system working smoothly when switching chainwheels. Before going out for the first time make sure that everything works correctly.

You must never use ROTOR Q-Rings with a worn chain or in poor condition. This is part of the regular maintenance of your bike. The chain must be clean and well kept. Always use a good chain lubricant to improve the horizontal movement needed to change gears.

Last but not least, check the rear sprockets. If they are worn out replace them.

With the powertrain clean and in good order, the Q-Rings chainrings work just like regular chainwheels, only that you will benefit from a much more powerful and effective pedal stroke.
