They fit human pedaling motion perfectly and involve the hip joint to a larger extent, which takes the load off the knee, noticeably reducing knee pain if you suffer from it [with round rings].
With that, they have become one of, if not the most popular brand, engineering and producing Oval chainrings in the Bicycle industry. In their words:. Riders are simply applying less muscular force input for a given power output vs round rings , or in other words, it allows them to pedal at higher power outputs with the same effort as with round rings before. It also results in improved efficiency, which is a metabolic measure the ratio between the mechanical work and energy expenditure.
With that, they have also become one of, if not the most popular brand, engineering and producing Oval chainrings in the Bicycle industry. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it or not , but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.
Without boring you on all the numbers and science behind why and how these do such a great job, we will just simply say that with the decreased amount of effort a rider gives and a more consistent pedal stroke lead to an overall more efficient ride.
But wait! You may be asking yourself why does this really matter? Smoother power delivery to your rear wheel means that you will be able to maintain better, constant cadence; get less stress on the joints knees and therefore be able to keep a certain level of effort for longer. This results in higher average speed. Moreover, 11 studies made by various Universities in the World show that using oval chainrings human legs utilize more muscle groups compared to round one , but each of them to a lesser degree.
Load from pedaling an oval chainring is spread over greater muscle mass which in effect gives you the feeling of fresher and more relaxed legs. All-around shredder and customer service champion, Logan Ammon has spent some time on an oval-ring to see exactly what the fuss was all about. That happens when the long diameter sides of your oval chainring are at their furthest distance from the rear derailleur.
One interesting thing I learned while researching this article is that the difference in chain tension as the effective radius of the chainring changes is so minimal that you can even use oval chainrings on a fixed gear and single speed bike. When choosing an oval chainring, the most important consideration is that it fits your crankset.
Every manufacturer uses a different crankset mounting system. For example, Shimano cranksets require different chainrings than Sram. One brand may sell cranksets with different mounts as well. For example, Shimano uses different chainring mounts for their different groupset classes. Luckily, most oval chainring manufacturers sell multiple versions of their chainrings so they work with most cranksets on the market. Remember that more teeth give you higher gearing and fewer teeth give you lower gearing.
Amazon has an excellent selection of oval chainrings here. Oval chainrings are becoming increasingly popular among road and mountain bikers. They offer a number of benefits over round chainrings under certain circumstances.
If you climb ride in a particularly hilly area or have a less than perfect pedal stroke, you are a good candidate to at least give oval chainrings a try. Generally, mountain bikers benefit more from switching to an oval chainring than road riders. Maybe they experience knee pain. Where do you stand on the oval vs round chainring debate?
Share your experience in the comments below! For more info on chainrings and putting a drivetrain together, check out my 1X Vs 2X gearing pros and cons list. Sign me up for the newsletter! I compete in rowing and cycling so my pedal stroke could be smoother.
I fine oval rings smooth out m pedal stroke I don't go any faster maybe slower in tail wind but I can ride longer at higher average speed. That's interesting that they smooth out your pedal stroke. It seems like oval chainrings work better for some people than others. I use oval on my mountain bike and the climbing results are definately better.. Im less fatigued and quikcer up the slpoes.. It seems to help on climbs BUT it also seems to hurt me on very techy like trials tech where every movement of the pedal stroke is needed to propel me up onto and over a feature like big rocks.
It seems the weaker spots in the pedal stroke leave kinda just spinning with nothing happening and me vulnerable to loosing balance. I can produce a lot of power so I tried going up a gear but the difference in pedal force to the back wheel is hard to finesse.
Ever heard of this? Make sense? Or is it me? Nice article. Thank you for laying out the differences between the chairings. It gives me something to think about if I want to switch around on one of my bikes. Glad you found the info useful.
Let me know how it goes if you end up trying out an oval chainring! What Are Oval Chainrings? How Do Oval Chainrings Work? Facebook Twitter Pinterest Email Reddit. Click here to cancel reply. Bruce Tuesday 31st of August Furthermore there have also been some issues with the chain drop being potentially higher. And some say again that they are not recommended with singlespeeds.
And also some say they feel weird to begin with and this could be a feeling that you might not never get over. Personally if these oval cahinrings have you interested at all it might be worth trying them out to see how they work for you.
The benefits of efficiency might be worth it, especially for long days in the saddle. When looking at the oval chainring options available on the market. Each one serves a different purpose and benefits. Let me explain product by product. Then after we will answer some common questions and dive deeper into the pros and cons of Oval chainrings to normal round chainrings. All Absolute Black chainrings are compatible with 10 and 11 speed drivetrains. If energy saving is a priority for you this is the main reason to consider these unique chainrings.
In particular the Absolute Black are said with the same energy output with a round chainring you will consume less energy. Even though some mention these types of chainrings are not ideal for singlespeed. When climbing specifically this ring gives you more power to the wheel and is much smoother, and overall effort is put to the wheel way more efficiently. The Wolf Tooth Elliptical prides itself on being less aggressive then some of the other rings in this article.
