- I never really see oval chainrings discussed much. For how popular they are, there seems to be a stigma surrounding them that they're just odd. However, I think there's a real benefit and difference when using these chainrings, and I go into more detail in this video.
I was glad to see a video talking about oval chain rings and seeing it put on a single speed. Disappointed you didn't talk about chain tension and if it dropped the chain at all on your single speed. would like to try one but I ride single and I don't want to put a tensioner on their.
Great vid. All the info was helpful
I Run A 30 Oval instead of A 28 ..... I Like It ALOT More .... The Thrust Is Easy To Manage and EXTRA . Love The Variable Gearing 😎
hello which hub mounts on the bike of the video where mounts gx 12 speed?
I just got a wolftooth 32t to replace my shimano regular 32t. I could notice it quiet a bit around my block but even less on my trail, nevertheless I noticed it helping me. Its smoother less fatigue on my body. To me tho it doesn't feel like a 30t on the smaller oval side when cranking, more like a 31t but that still helps.i kinda wanna buy a oval 30t or a 31 if that exists, it just kinda pains me that in some cases I loose top speed easily on a 1x. I'm not racing but eventually I'd like to get back into it. maybe I should buy a shimano or sram 12 speed. I have shimano 11 speed but have my eyes on shimano 12x .
It makes sense.
These are interesting. I was once pretty good on a road bike and central to that was learning how to spin effectively. Not just pumping down on each stroke. By learning how to apply pressure to the pedals through a greater section of the circle greater efficiency is achieved. Much greater. Learning how to spin properly increased my performance by 20% at least. I am curious how these oval chainrings affect spin since clipless pedals are used much more frequently on MTB than they used to be.
I wonder if it makes your chain any weaker ? I'm considering using one for a dirt jump bike
Have you had any problems with dropping the chain on your single speed?
Seems like there is a large slack section when you’re paddling.
What is your single speed gearing ?
Am I wrong or the oval chainring id installed the wrong way?
installed correctly, described incorrectly
1:37 installed incorrectly
1:51 installed correctly
I wondered why he never explained how to correctly install it
If you put one of the oval chainrings on a bike ,do you have to put them on all your other bikes?
Not at all! I actually just put one on a bike to try it out. I liked it, so I bought some more.
I got my asymmetrical chainrings, 2g Doval 52/36 and a 4g 52 single ring. I've ridden them for a few weeks now and really like them. I have another bike with round rings. When I rode the round rings it felt like I was slogging through mud . My legs felt like they were working really hard. Going back to the oval rings felt like I was trying to hurry my pedal stroke to catch up to the crank. That being said, I ride both bikes equally now because both chainrings work different sets of muscles. The asymmetric rings to me are faster with less effort and they seem to climb better. However, I dont think they sprint as well. That's no loss to me because the races I do are 12 and 24 hours long. I can't see a sprint happening there. Maybe a good plan would be using both bikes in an event and switching when I get tired. Too early in the season to tell just now. With the Corona crap I don't know if the races I'm looking forward to will even take place! At first I didn't think there would be any difference between the rings at all but I do think the asymmetric rings are easier on the legs but only time will tell. I've read some posts where folks have tried the oval rings and say they feel no difference at all but I can't see how they can say that unless they are numb from the waist down or haven't really tried the rings at all. I hope this helps someone. I really like the asymmetric rings but the only drawback to me is that with the aggressive rings the 2g Doval is 22% asymmetric and there is a slight chunk,chunk sound in the small ring on the extremes of the cassette that also happens in the big ring on the extremes of the cassette. It has gotten way quieter since the rings were new but it may annoy some folks. Overall I like them!
You actually spend more time in the deadspot, meaning your knees have more time to change directions making your pedal stroke smoother. You had it 100% correct for 4 minutes but got it completely wrong at that point. If you spent less time in the dead spot, your knees would whip around in a very uncomfortable manner.
With an oval chain ring you usually ride in a higher gear anyway so youre knees wont be whipping around. I got an oval chainring and i actually have less knee pain than i ussually would
@@michael0450 While reduced knee pain is the result, the oval chainring simulates a higher gear in top dead center and bottom dead center when properly installed. This slows the whipping down so that you could, if you chose to, spin a LOWER gear without damaging your knees. Using higher gears is also available since the shift to the power stroke feels smoother, thought you're not getting the full benefits that way. Try spinning a little more and seeing how it feels. However, as always, if you are able to bike for years without pain or stiffness keep doing what you're doing!
James McPherson if the chainring is installed correctly it should go faster past the deadzones and simulate a harder gear when in the powerzone
@@michael0450 That is incorrect but a common misconception that is spread widely because it helps sell oval chainrings to people that don't really care to think it through. While you could install some chainrings that way, it would reek havoc on your knees and offers no actual performance benefits. It would also reduce traction on climbs as you would experience exacerbated power spikes on that would break the tire free. Installed correctly, oval will mitigate power spikes by slowing the transition allowing you to spend more time close to that breaking point giving overall higher traction. The slowed transition also allows your leg muscle systems time to switch from lift to push, allowing much more efficient pedaling, making it feel like you can push a bigger gear or spin a lower one. The biomechanics of our legs' ability to switch directions efficiently is the limiting factor, not the available leverage in the power-stroke position.
James McPherson but you would have more traction with a bigger chainring because there is less torque going to the back wheel and surely you would want to spend less time in the deadzone
I tried an oval chain ring once and it bent under pressure of my foot when I was in a higher gear. Never gonna use one again.
You broke an absolute black chain ring?
Total wasting of money! I have 2 oval chainrings,and I have never ever felt any benefits of this nonsense! I don't own a car, so cycling is my everyday habit,and bicycle is my only transportation,so,a experienced 'cyclist'
Keep your money, don't get hyped!
Peace,and greetings from Croatia from Kris 😊
I agree that chainrings are important.
I cannot understand the price.
