    Sort of the same for me. In fact, I run a Wolftooth oval on one bike and a round ring on the other. Both rigs get about equal ride time. If there is any difference, it's not something I can really put a finger on.

    I'm wondering if this prevents a) muscles completely adapting to the oval and/or b) prevents "shock" by keeping your muscles adapted to both.

    I had the worst cramps I've ever experienced when I hopped on a bike with round rings for the first time in months.

    I use to get cramp, on round when I first started out...

    Then I went Oval and cramp went away.

    Back on round (for just a wee while), no cramps yet.

    Think Oval taught me how to pedal more efficiently ;-)

    The WT feels more natural coming from round rings than the AB. It's a subtle difference, and I adjust to either one pretty quickly, but the WT doesn't feel as weird as often, and I don't feel that the AB offers much if any performance advantage. For me. I also like that the WT is made in the U.S.

    Going back and forth between the ovals I have (OneUp, Garbaruk, AB, and the Ridea SXX1)...I can't really tell the difference the way the rings are clocked. All I can really tell is that they get me over the dead spot at bit quicker.

    That's what people keep telling me. For whatever reason I'm just as good at dropping chains off of bikes as I am at tearing knobs off Schwalbe tires. Without a good chain retention device the chain just isn't going to stay on for long.

    So a 30t oval correlates to a balance of 28/32 rings depending on the point of rotation? Or is it more of a 1t variation either way?

    Thanks in advance.

    In my book 30t is 30t. Oval may have a smoother power delivery, but it still moves the same amount of chain every revolution. Smoother, but it's not magic IME.
    I got some bad ideas in my head.

    is that right? id assumed an oval ring - because of the radius at the point of drive from the bb centre - acted as a 2 teeth bigger ring. i assumed as much because the chain is only ever on so many teeth, so the radius seemed the most important factor - ie the leverage of the power delivery?

    You are moving more chain when your legs are making power, and less when they are not. I don't feel that I can push a bigger gear, but do feel smoother power delivery. 80 rpm is 80 rpm, round or oval. Maybe others do notice a bigger difference?

    The big difference I have noticed is knees. On 20+ mile rides my right knee would really start to hurt with round rings. I have done 30+ on oval with no issues.

    Hhmmm. The old guys like me insist it's helped with transferring better traction and more importantly knee pain. 😜

    I agree on the traction, but my knees feel about the same.

    I've never heard of an Enduro race that had anything other than fire road climbs.

    Well, lift served, I suppose, but "technical" climbing is not really a thing I, or most people, would associate with Enduro racing.

    I have an Absolute Black 30t Oval on...

    28t at its narrow point & 32t at the widest point.

    Smoother power delivery around the full pedal stroke.

    No dead spot.

    No hanging up during max.

    Easier on the knees.

    Legs, lungs less fatigued.

    I hate that!! ;-P

    ab, wt, 1up, are just a 99% copy of the rotor elliptical - without the adjustability-which is key to clock the shape to your pedaling style. Rotor rings were made for road bikes. They were designed with round and regular pedaling in mind. They are good for classic xc/marathon.

    If you like the elliptical and want to try something that helps more with quick acceleration and good on mashing, I found the asymmetric rings being better.
    O-symmetric and a bunch of European brands make them (ari, carbon-ti, frm, stronghlight).
    Going from elliptical to asymmetric is the same difference as going from round to elliptical.

    Getting another Absolute Black is quite ok with me, though.

    Just from eyeballing them, I'm not seeing much difference between AB's shape or clocking and Blackspire or OneUp's. Not perfect, but I got these lined up pretty well with the photocollage thing on my phone:

    Oh crap, I thought it was broken. I held them up against each other and they were extremley close. My BS replace AB.

    I've got a OneUp (also picked up for $30), Absolute Black, Garbaruk, and Ridea. Honestly can't tell the difference in clocking on the rings.

    I came across a German bike site (through Google Translate) and read that on back to back tests...they can't tell the difference in clocking on a AB and OneUp oval.

    Oval rings have now been added to my long time "no-brainer" list of...

    King rear hubs
    Oury grips
    Rethal bars
    XT brakes

    Oval rings create a subtle, yet positive difference, in the motor. And no negatives, except a small additional cost.

    I think I'm going to make a separate post.

    Just reporting my initial impression of round to oval.

    Yesterday was my first ride on a 5010 that was converted from 2x10 (22/36 with 11-40t) to 1x11 (30t 1up oval & 11-50t - m8000 with 1up 50&18). The whole drive train was replaced with moving to XTR shifter.

    For the first few miles I was constantly shifting just to get the feel of the system. Had to stop and move the brake & shifter outward to get it in the right position for me. Then I started going through each sprocket with forward, then back pedaling to evaluate chainline and see if I was going to have any dropping between sprocket while back pedaling (common report). I had no issues, everything was shifting very smoothly.

    Finally, after several miles I remembered the oval! By then it felt perfectly natural, I couldn't really tell any difference in the stroke. Took in up a climbing trail where I spent most of the time in the 37 & 42t sprockets - again very smooth transfer of power. The last couple hundred ft of trail ungulated and got steep enough that I needed my 50t. Again very smooth transfer of power, no lose of traction while riding near my climbing limit.

    Positive initial impressions, but I have so many changes going on that I really need more mileage to truly evaluate the oval. One other impression is that I may get a 32t or 34t chainring for long rides that don't have steep climbing.

    After a few weeks, put a 30t round ring on and compare.
    I hated the round ring in low cadence, high power situations after being on oval.

    I had a 3x on my old Trek Fuel Ex9 and I replaced the middle ring with an oval. After a while, even if I would change the ring to the smaller or bigger one (which where the original round ones) I was barely noticing the difference.
    Also, the brand I had, had 3 different mounting positions. So you could change the setup based on what you liked best. Unfortunately I don't remember the brand
    Edit: I found the brand. Q ring

    Increased traction, decreased knee pain. Worth the price to me for those two benefits.
