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.
