Smooth Pedal Stroke & Great Traction

  • Familiarity: I've used it several times

Setting up the chainring was a breeze once I had the correct crank puller. After I installed my new gold oval chainring, I went down and hit the Slaughterpen trails in Northwest Arkansas. I immediately noticed that my pedal stroke felt much smoother. After a couple of techy and steep climbs, I quickly began to notice the subtle increase in traction. In climbs where my rear tire would usually start slipping, I suddenly had more traction and was able to climb through it. Maybe this is just in my head, but I also felt like my legs weren't as fatigued at the end of the day compared to my previous chainring. So basically if you're in the market for a new chainring, I would highly recommend the Absolute Black Oval ring. If you buy one and don't notice a difference, it was only $70!

Great traction

  • Familiarity: I've used it several times

Works really well, smooths out my pedal stroke and makes it easier to get good traction on steep, techy climbs. Mounts great to my RaceFace crank. Only issue I had is I tried to retrofit this one to a boost bike, and it was way too close to the chainstay. Absolute Black makes a separate one for Boost bikes, and we have it in stock.

Hi, is this the new model with the offeset for improved 49mm chainline?
The old model had a 52mm chainline.


Hi John, These are the newer 49mm offset chainrings.

Consistent Power

  • Familiarity: I've used it several times

I am running this ring on my rigid single speed and aside from the setup being a little different than what I am used to, it works really well.

On my first ride, I noticed an obvious variance in my pedal stroke and feedback, but by about an hour into the ride I seem to have adapted to it and I no longer noticed any irregularity. I did notice an improvement in the way I was delivering power to the rear wheel. More consistent power throughout the pedal stroke, it seemed like I was able to get through the dead spot, or weaker point in the stroke more quickly, allowing me to stay in the power. I also noticed better traction, likely as a result of the more consistent power to the rear wheel.

Setting it up, since it is an oval ring on a single speed with no chain tensioner it took a little extra attention. Initially I had just a little too much chain tension and had noticeable resistance at one part of the stroke where the most tension was on the chain. By backing off of the tension just a little the problem was solved.

I would recommend this chainring, it is worth a try and if you need to replace your ring, why not. I will continue running it, and when it eventually wears out, I will buy another Absolute Black oval ring.

Any Questions about this chainring?

Will this work on a bike with a boost axle?

Hi Luke,

There is a Boost version of this chainring that Absolute Black makes, but we do not currently have the Boost version in stock.

Great Upgrade for Your Bike

  • Familiarity: I've put it through the wringer

I really like the elliptical ring. I think my pedal stroke feels smoother and I can last a little longer before having to gear down. I am not noticing a huge advantage, but definitely no disadvantage. If you are in the market for a new ring, go for it!

1x + elliptical ring = sweetness

  • Familiarity: I've put it through the wringer

I've logged over 5,000 singletrack miles the last few seasons using an elliptical ring and have yet to drop a chain. I'm a huge fan of the rings in this application, but admittedly most of those miles have been on a Rotor setup - crank & ring combo. It was flawless.

So when I recently got a new whip, and my Rotor crank wouldn't fit, I was pretty bummed, and had to look for a new solution. Absolute Black nailed it, and after a couple hundred miles, I'm all smiles, and likewise have yet to drop a chain.

In all fairness, the pedaling has slightly more feedback on this ring than I had experienced with the Rotor -- it's not enough of an issue to reconsider my build, but worth mentioning.
