I used to have Oval Rotor Rings, they were awesome for a long while, zero issues. Then there was that one day, my Oval ring kept on dropping chain during every shift on the front mech, that was the day I decided I was just done with Oval. I did realize the power gain and less fatigue. It took a little while to get used to the Round Rings again. However, I have never looked into Oval again unless the bike is a 1x. My chain drop experience was with DuraAce 7900 group 10+ years ago. I have always wondered if I had that set up again in the modern Di2, if that would resolve the chain-drop issue, Although I wondered many times, I am still not willing to try again. Any feedback would be greatly appreciated!

Is that like a 56 or 58t Dayum that chainring is massive

Can't wait for these guys to turn up, suffering with dodgy toes so the wider future will be plush

Unfortunately, it’s an issue with your power meter and probably not your hip.

Come back in a years time and tell me they're great. They wear really badly because they do not have shifting pins.

You've got some work to do to sort your imbalances out. The chain rings wont solve anything. Nor is there any evidence to prove that they create any power improvement. Absolute Black isnt a great company either

are there different oval implementations. Like 2:05 looks like the oval is ~120° off the crank whereas in others it seems to be more like at 60°

In the tests I've seen they never say what sizes they are using, a 32t round, vs a 32t oval is an unfair advantage, I call a 32t oval a part time 34t because of the height.. just go from a 32t round to a 34t round and you'll see a good improvement.. people changing from a 32t round to a 32t oval should see a difference, its TRICKNOLOGY !!! it sells stuff, I'm waiting for oval wheels...;) !!! Pro rider Dylan Johnson rode oval 2 years now what does he ride on? kzfaq.info/get/bejne/oNp6ash63te1YHk.html

will the 56 cm fit a 6'2" guy?

Me resultan muy incómodas las lake cx 238,tienen demasiado arco en la suela,yo tengo el arco pronunciado y pensaba que me irían bien,pero se clavan el la parte exterior de la planta del pie,es un suplicio al llevar 2horas

I purchased this lake shoe in 2021. What a difference in comfort. I have a broad foot so happy to have found lake shoes. I purchased them from RXM Custom, being able to try shoes on to obtain the correct size. Great service from them.

I think your glutes should be doing the pulling --- the scraping the mud off your feet and pulling part from about 5 to 7 o'clock whereas your quads will be pushing most at from about 3 to 5 (but also if you sit far back, earlier allowing one to push over the top, from about 12 to 3 as well). I think that the "smaller muscles" don't really do much. But, as you say, the big part of oval at around the 4-5 allows for greater power output when the main muscles are working, (both pushing and pulling) and less when there there aren't. This allows people to put a bit more power out, I guess, and makes the bike more suited to the rider. Shimano Biopace did the opposite, taking the strain off the main muscles and requiring power in the dead part of the stroke. I guess that they were 1) for old people (like me) who want to put less strain on their knees and 2) to train people to pedal more smoothly so that the rider becomes more suited to the bike. I am surprised that you did not Biopace (rotate) your AbsoluteBlacks if you had hip pain, but it worked. I see that there are Litepro ovals very cheap from China but I am scared that I will not be able to set up the front derailleur. The microphone you use from 5:34 is so good I thought I had swapped from my headset to speakers, or had you in the room.

What’s the lowest temperature you’ve used these at with road shoes and still felt comfortable?

Just fitted them to my road bike, if you want proof they work pedal with one leg; You really feel the effect of being able to maintain a full circular pedal stroke.

Why don’t you get Eddy Merckx to explain how he did it. Typical modern day bullshit.

Most pain issues are the result of muscle imbalances or poor bike set up. I tried oval chainrings for a few years and found they made no difference to my muscles. What I did get was a lot of chainsuck issues which is really annoying and can damage your frame. To be fair to Absolute Black, I had chainsuck mainly with Rotor chainrings and not the AB ovals.

Thqnk you, very useful to know

I am thinking about invent oval wheels or front oval rear circular or vice versa....

Some materials I've read somewhere mentioned that power meter is not accurate on oval chain rings. Have u noticed the difference so far?

I get the impression oval chainrings suit a spinner more than a big gear grinder. Cadence is surely more facilitated as a result.

I mountain bike. I don't even notice mine is on until I start to climb some steeper rougher terrain I like the oval chain ring

I wonder if they can make oval cassettes to go with the chainring oval?

great review very genuine

Thanks for the video! I felt the same on my first ride today, a kind of pulsating feeling, but it quickly disappeared. Lately, I'm also experiencing some right hip pain, so I hope these oval rings will help alleviate that. Also, switching from Ultegra 52/36 to AbslouteBlack 46/30 should help on steep climbs.

I am glad it works for you, Nuno knows is busines , ride safe my friend 😎👍

2 things! Soreness on 1 leg maybe due to height differences between legs. Sometimes we bikefit the wrong leg! Try shims to see if goes away. 2nd! Performance improvements are easy to demonstrate. Get indoors. Get power. Run both systems and prove the one you are selling uses less watts to maintain the same rider at 40 km or such.

Great video, thank you!

Buenas noches, funciona bien con el desviador di2? gracias

You feel difference in putting down power?

Interesting stuff - would be good to see some more info on what was found, and how your position/set up changed.

You've sold them out everywhere :) :(

you can buy a neoprene wetsuit glue that works really well, certainly did on my wetsuit and lasted for 8 years in high stress and movement location, about £8 a tube.

Helpful review mate 👍 I'm getting these. And for that rip that you have got there I would recommend black witch neoprene glue.

Those glove are not worth £80!!!!!

The fitter had pressure mapping for the feet?? That's really nice. In my entire country I know of anyone using pressure mapping whatsoever.

dark chocolate often has milk in it

Where did you get the CX237? Those are hard to find now

Which Polish Spray?

I just bought pair. I too have wide-ish feet. Not had a chance to ride in them yet, but coincidentally, I have also put my cleats right back and going to see how it feels. I certainly find I curl my toes though. Where did you go for your bike fit?.....1 hour later, watched all your videos. Sent Orbis an email.

I had cx237 since 2015, still using now!

Nice video! Let's be KZfaq friends!

Carb up Tom.Put on weight.Focus on TTS.You know it makes sense.

Will there be a episode dedicated to dynamo’s?
