It was more than a century ago that the bicycle was invented and chainrings have been one of the components that have changed the least in appearance, but they have changed more at performance level. Yes, ROTOR oval chainrings are more effective than their round counterparts, but that does not mean ROTOR will not continue to develop them.
It’s up to you. You may be fully convinced of the benefits of the ROTOR oval chainrings and do not consider going back to round ones, but it may also be that you are comfortable with conventional chainrings and want to continue using ROTOR for the quality and performance they offer. If so, read on why ROTOR keeps making round chainrings for all of you.
If you visit our website you will see that we offer many of our chainrings in both oval and round versions. Oval chainrings are one of the products which ROTOR is best known for. Their advantages are evident; oval chainrings will allow you to carry a higher cadence, so that muscle fatigue will be less by avoiding those pedaling points (which exist to a greater extent in conventional round rings) where muscle power rises without it feeling reflected in a higher speed or better wattage performance. In addition, thanks to a more fluid pedaling, it prevents those spikes in muscle and joint tension, they will be a help if you are prone to having discomfort in your knees or hips.
It is as simple as the cadence increases, muscle expenditure is less due to not having as much tension, and the articular points make the entire pedaling cycle easier. In addition, and depending on the type of Q rings you use, in the case of those that come with OCP technology, you will be able to rotate the rings themselves so that the maximum pedaling points (greater ovalization) and the minimum (less ovalization) adjust to your pedaling preferences.
Even with all the advantages of oval chainrings, ROTOR round chainrings are manufactured to the same standards as the rest of our products, achieving rigidity, lightweight and compatibility with most of the transmission systems and cranksets on the market. The options on round chainrings that you can find on our website are almost limitless; direct mount (DM) for single or double chainrings, aero, chainrings with a 110×4 spider (BCD), spiders type DM with five arms … In addition, our round chainrings are also compatible with our INpower cranks with a built-in powermeter. The round chainrings are also made of 7075 aluminum and with CNC technology, in the same way as oval versions.
Many of you are also users who rely on round chainring systems because they have always worked well for you and adapt to your pedaling and why not, simply because you prefer the ‘usual’ rings and you do not have to switch to oval ones. For those of you who identify with this more ‘traditional’ way of pedaling, you can always continue to use round chainrings, but due to the enormous difference and benefit when pedaling that ROTOR oval rings offer, we encourage you to you try to compare the sensations and the greater performance that is obtained with the oval versions.
Also, at ROTOR we have wanted to continue offering round chainrings of the highest quality, for all those who use several bikes and do not want or cannot have two different pedaling systems. It is true that once you get used to the fluidity of the oval rings, returning to the round ones or alternating them is not the most appropriate because you can have a reading of power and cadence data somewhat altered. For this reason, many have preferred to continue using round chainrings until you can mount oval systems on all your bikes.
Obviously, it is a personal option to opt for one type of chainring or another. At ROTOR we encourage you to try oval rings if you have not already done so and see for yourself all the advantages that we have discussed on several occasions in our blog. And if we cannot convince you and you want to continue using round chainrings, you know that the ROTOR products are manufactured to the highest quality standards. Maybe we have been using round chainrings on many of our bikes for over a century, but it also may be time for the world to become ovalized.
