Nice test, thanks!

Getting free stuff. Absolutely brilliant. Fantastic content Darren.

Well done sir. Congrats on the freebie.

I've been riding the absolute black chainring on my Jeffsy for about a year now. I share your impression that they help to put down the power more evenly in steep terrain, so when I ride with very low cadence and high power. So especially in technical parts of climbs I feel they help to keep a steady pedal stroke and keep the momentum over roots and rocks more easily. I have to say I noticed a slight "pedal wobble" on my first few meters in the flat on my first ride, but that feeling went a way in a few minutes of riding. I used a rotor oval chainring for a while on my XC bike but went back to the original round ring because the rotos chainring was quite noisy and didn't engage the chain smoothly. The absolute black in comparison is just as smooth and quiet as the original chainring.

Really interesting video and congrats for the swag! I have been wondering about those oval rings, maybe time that I give it a go

Good comparison and I liked your choice of music when changing the rings!!! ;-) I've been wondering about an oval chain ring for sometime. May well give it a go.

wowwww this vloggers are great thanks brother♥️♥️♥️♥️♥️

Beautiful trail bro. Nice ride

Good comparison! I recently installed one on my bike. They make the climbs less exhausting.

Amazing

Good Vid 😎 Thanks i just got a 30RF Oval For My CF Warden . Just waiting for it to Show up 😁

I can agree with you first few days you could notice the difference but now wouldn't go back started on a 36t was ok till winter came then put a 32t on and now got easy into hardish gears makes going up hill a lot easier

Three thumbs up!

This is my biggest issue l am having. On our hardest climbs I pretty much now only go down to 1st gear (1by12 (30,10/50) for the worst part of the hardest climb. I want to try and run the shifter in say 4th,5th,6th rather than 1st,2nd,3rd so was going to go to 28t oval. Most saying say same or go bigger (32t). What advice would the majority give?

Did you make sure the chainrings were similar sized and that you switched gears identically on both tests? Otherwise too many variables are in play to make it a decisive conclusion

interesting thank you! can you please clarify what size was the round ring and what size was the oval? ta

Idk if its placebo effect but honestly you just get better in climbing the more you do it. I would train on steep long road climbs between trail riding.

I have an AB oval on my Norco. I ride punchy climbs with lots of rocks/slabs lots of power moves. I have no idea if ovals would help with speed but it definitely helps give you an extra crank through at the end/top of the climb (usually at the point of fail). I noticed this on my very first tech climb after installing it. I had that same experience a few more times during that ride and subsequent but it's a subtle change but in the positive direction. A year later I still fail on climbs that my riding buddies are clearing without oval chainrings but I'll take whatever bonus I can get.

would you say you are less tired with the oval?

My other xc bike has an oval ring for 4 years now. Ovals for me feels weird on paved uphills. But it definitely helped me on technical climbs or uneven terrain. Who spends so much time in flats and paved roads on a MTB anyway?

I changed to an oval chain ring about a year and didn't notice when riding but I then found I was getting strava pr's on climbs so I've stuck with it .... in fact recently bought a new won & a bash guard so I don't break a tooth 🤦

I run round on my road bike and oval on my MTB's. It seems to me that the rounds are better on the road even with some climbs, whereas the oval is better in climbs on uneven terrain and going over roots and rock gardens.

Was there a difference in the number of teeth on the two chainrings?

i will join in race for mountain trail sir . 28T is good for me ?

Would something like an Oval Chainring matter for an eBike?

Iv been using a oval ring for about 6 months I prefer it

Hi. Very informative vid. What size of oval chainring should I use for my 27.5 mtb, 11x46 cogs. Currently using 34t chainring.

I see in the background he built Blake’s (from gmbn) bike rack and shelves

I think ovals work on power delivery better than round. Try accelerating on some single track and see what its like.

How many teeth were on both chain rings?

I wonder why the winning xc racers don’t run them, if they work so well?

Quite a difference in times there, may not be in depth scientific but it was a real world test and that is what counts 🤙🏼 Check you out getting freebies now 😃

wow this helps me a lot decided ill get one for my e-bike my mechanic friend said they won’t make any difference on any bike but seeing this video made me see they do make a difference think he just hates oval chain rings lol

you didn't say how may teeth each chainring had, if they were both the same count of teeth the oval would have a big advantage, the oval is taller, a test of a 32 oval vs a 34 round is a much fairer test..

I'm getting an oval!

Hi its me 🤪🤪

Haven’t watched yet but if the winner is “round” I’m calling BS.

Sounds inconclusive on the hills. We must also factor in the bias of receiving something for free & wanting more free stuff in the future 🫐🍆
