The Ultimate MTB climbing upgrade!

- Will an oval (elliptical) MTB chainring - coupled with shorter cranks make you a better rider? Probably if you have to climb any hills.
Here I am, 160mm Goldix MTB cranks upgrade and an oval chainring and it's pretty awesome. I had my doubts but after a couple rides I have to say that for me - it's the perfect set up.

The trick to oval chainrings that nobody tells you is to use a chainring 2t smaller than you started with. In this video, he already went from a 32t to a 30t, so when he went oval it was the correct set up. Using a 32t oval chainring on 29" wheels will actually feel like you added a tooth or 2 to the front chainring. So, to compensate use a 30t oval on a 29er and you will notice the difference.
Don't you lose even more top end speed dropping down shorter cranks and chain ring?
It might help with climbing, but I think maybe I'd lose too much top end.
That's good to know cheers!
Round chainring makes my knees hurt, it's agony, so I stuck with ovals. It made a big difference on climbs for sure. I can ride for longer, push harder, and no pain in my knees, just normal fatigue in muscles. It won't add much wear on the RD. I never noticed it.
That's one of the reasons I will stick with traditional drivetrain instead of going to a gear box. Maybe someday when the chainring moves with the crank.
Yeah, I'm in agreement. Running 165 mm cranks at the moment and an oval chainring on one bike and a round one on the other. I could probably drop down to 155 mm cranks since I'm short. Both the cranks and the oval chainring help out with smoother pedaling and less knee pain. You simply spin more and mash less. 👌
I have kind of a mash going too with the one bike running 160s and oval and the other 170 and round but that bike has more ground clearance and seems to work out fine for me (trail bike.)
Hi, do you happen to know the q-factor of these cranks?
Is your stance narrower than let’s say “normal” mtb cranks?
Cheers from the Philippines! 😊
Interested to see how these would act with the torque on a mid drive now if it'll give you that bit more power down
@@EMTBonsai Interesting thought, would oval even matter on ebikes?
I tried oval chainrings on road and mountain bikes and didn't notice much difference compared to round when riding hills. On flat ground the round chainrings were better. That was in 1990 when oval rings were the newest great thing.
There's data to back it up but from what I've read, if you have good cadence you won't notice much difference.

1990?? It's been raining since then... Also you should know that those Shimano "biopace" chainrings were terribly designed in fact they had the ovality just the wrong way round!! In the blind spot is when it had the greatest diameter.
So , my usual ride i have 3 challenging short punchy climbs that i've never cleared due to my rear wheel spinning out
recently i changed to a 165mm cranks and downsized to a 30T absolute black oval from a 32T round.
First climb i made it 3/4 of the way till i hit a dip on the rocks .
and the rest of the 2 i cleared it first try.
all of the attempts not one rear wheel spin out .
apart from that , i felt my pedal stroke is smoother and more efficient
so its money very well spent.
Pretty cool how this seemingly small change can make such a difference. I changed my rear tire a few months back for better traction, maybe you should consider that.
@@VisionMTB I'm at that cusp of technical inability and equipment capability , I will try upgrading my skills first
i am running stock length cranks, i am 6'3", but i have the wolf tooth CAMO system with a 32 oval on my 27.5x3.8 fat bike. i really like this setup. the CAMO system lets you change chainrings without taking the cranks apart. I think for certain races with lots of climbing i could go down to a 30 but they are never in stock.
Huh, I think I have to check this system out! Wolf Tooth makes good stuff.
@@VisionMTB they certainly do.
Maybe can lower that music a tad in background its quite loud watching it on tv or tablet without headphones
