The amazing thing for me to see here is I had no idea how much flex you can see in front forks just before compression.
Forks' flex is always surrealistic when you watch this... as well as the rear derailleurs' ballet (and despite of their clutches).
@Pinkbike we need to see a huck to flat fork experiment.
Dual crown, single crown, big tube single crown and USD.
Team Zeb/38 says it's stiffer, team USD says USD is stiffer.
Who is right?
The amount of frame flex, chain slap and tire compression is an eye opener. The amount of stanchion flex, twist and deflection of the forks is actually quite scary.
Flex = comfort and compliance, not necessarily danger. If you want a responsive and rigid ride, you have to make some compromises. A stiffer fork will stress the frame a bit more and possibly fight the rider. Everything works in harmony, and the right formula will vary from person to person
Where are you seeing frame flex?
In the tubes at the gooseneck in a couple of the bikes near the beginning. More interesting is the difference in the number of major impulses hardtail to full sus in the compression of the fork.
The forks flex due to brakes being applied. Same with the bobbing rear suspension compression. Some rear sus are better at mitigating this issue but a fork will always flex when brakes are applied
You definitely want some flex in both the frame and forks,handlebars etc,if they were too rigid they'd just snap in half on the first bigger impact
6:29 that looked like it could have hurt.😮
But those 5.10s right
That doesn't look like it was a carbon crank. I'm suprised it broke 😮
@@FIGHTTHECABLEthat does look like a carbon crank and is actually a carbon crank 👌😅
carbon crank powa 😅
Wow, ain't buying those cranks, what are they?
A picture is worth a thousand words! This is a priceless tool for seeing so many of the top rated frames
flexing in the frame and bending the front shock forward, chain slapping, and the overall manners weather, it's good or bad mannered. This is one heck of a reference guide, and I thank you so much for all your hard work putting this together. Thank you so much my good brother!
Watching a coil spring fully compress is oddly satisfying.
Crank arm rip off was epic!
That was so sick! New fear unlocked for sure! 😅
Looked like the insert on carbon cranks
That Starling! So smooth!
That was a pretty epic compilation
Incredible slomo. Is it just me that is seeing the flex in many of the handlebars? Some much more than others, I believe.
As always great content 😀👍
5.36 Absolutely blown away with that Giant Trance X Derailleur spining right up into the chain stay That's frightening!! Just can't get over how all the rest just don't go past a 90Deg and that Giants goes the whole 180! That's an expensive accident waiting to happen!
Ha ha I saw this as well... and still can't believe what I saw :)
looks like the clutch was not on the derailleur. I have the same bike and have never had that issue.
Best Christmas ever!
Odly satisfying to watch 🙂
The christmas present we all really needed
Me, waiting for my bike:
Never seen a crank arm fail like that!😳
4:00 Ibis Mojo
5:25 That’s my bike!
The hardtails put less weird stress on the forks. I didn't expect that.
same here. Fork flex is a thing.
@KeywordManagement how did you not know about fork flex?
Do you not ride a bicycle?
I think it’s the way they landed. The forks also flexed more when the rider applied brakes.
Obviously the bigger the suspension travel the more they send it, so the more we see the front suffering, neverless some forks surprised me for being super flexy.
Those two Marin hardtails are so cool!
Something else I noticed is you can see the different levels of damping on the rear shock, but they all appear to bottom out for sure.
Thx, my knees hurt now.
5.36 Giant Trance X check that Derailleur!! Practically spins up to the chain stay! That's abit much! Cool to see all this but this was some spring back on the Derailleur only on this bike rest are meh OK but think if bike companies seen this they might change them springs! Great video
I think what a lot of you think is frame flex is actually the rear suspension engaging first, slackening the bike. The actual front triangle isn't flexing that much
Its so satisfing 🙃
that is some harsh landings, hope your knees and back are good.
6:29 the crank snapped WTF.
Pivot frame suspension seem to be really good on big drop.
Where do u get all the bikes from? Do u rent them?
At 6:30 when the crank leaves the chat 😬
@6:30 Broken crank from a normal flat, good lord are they checked and withdrawn from the market?
The crank arm snapping on that Specialized Turbo Kenevo wasn't a good look 😵
Hardtails are built different
Hey, if it dosent bend it breaks right. This is modern engineering at its finest
Thats a good point
Some of the derailers look like they are shattering on impact!
Got the snapped off carbon crank on the Levo, but not the disintegrating rear triangle on the Pole a few years back, I remember when they had a rear triangle basically turn into an overpriced CNC machined noodle. Also pour one out for Jason Beer's knees haha.
I was a little disappointed that they omitted the Pole. I still remember their "prototype" excuses. I'm glad no one was hurt on the things since the reviewers had to ride the sketchy prototype parts.
That’s a lot of very expensive bikes 😮
Ah well that S works Kenevo Turbo crank arm clean snapped right off I was away to buy one these e Bikes wonder if this happens alot with these cranks on them.?
Still need to do a GT hardtail. I wanna see if that triple triangle works yo
It's beyond me why the industry isn't pushing more towards USD forks... the flex on these are just insane.
True, even though I'm not worried about the flex actually, but upside down forks just make so much more sense lol
actually there are reasons behind this, it's not like the bike industry never tried USD, it did, just that USD had proven not that beneficial as you think, and there are several obvious reasons as following:
a: almost all of the mtb forks are "unbalanced" if that make sense, meaning one side is purely spring unit and the other is purely damper, this has proven to be the method of saving weight and provide good enough support for what human power can put onto it. But this creates uneven movements from left to right so a bridge between each side will help a lot with lateral flexes. while moto forks are generally balanced with both sides having damper and spring unit so this isn't an issue so they don't even need a bridge for right side up forks.
b: that magnesium lower is just an engineer marvel. Being one of the a single unit that cost the most on the entire bike molding-wise, that lower provides enough stiffness to support the lateral support that mtb forks needed while also reduce A LOT of weight, since there's no aluminum counterpart nowadays so it will be hard to compare but it was something like more than 300g of weight savings 20 years ago with even better stiffness and strength, and 300g is quite a lot on mtbs, don't know who came up with the idea but magnesium alloy is just the best suited material for lowers.
c: USD is not as perfect as you think, more prone to leaking, more lateral and steering flex because there's no bridge, a lot more prone to damaging stanchions that compromises sealing and smoothness (that's why all the USD forks have boots, and if anyone is trying to sell you an USD fork with no boots, stay away from it), saving weight and reduce flex? yes if everything is made outta aluminum and a bridge between each sides is not allowed, but that's not the case on mtbs. Can't remember where I got this calculation from (from an engineer in one of the big twos actually but i can't say who) but if all things (damper design, spring unit etc.) are equal or similar, an USD fork will need to have similar upper tube diameter to modern right side up fork's stanchion just to be competitive weight wise, that means if someone is trying to build an USD fork that weight similar to ZEB using current designs and technologies available, the upper tubes will also be somewhere around 38mm or just a tad bigger, and that won't be reducing frontal flex at all while introducing all of the other flexes... so people just ditched the USD idea.
btw it's also A LOT cheaper and less problematic/less tech intensive to make an USD fork compare to modern right side ups because there's no need to deal with that magnesium lower, but people stay with the more expensive and complicated method... this pretty much explains everything. It's not like the industry is stupid, there's always reasons behind things
@@colebtl that's actually a really good explanation, on anything else than a DH bike I wouldn't run a USD for actually and I think the DH bikes are exactly on the edge of where a upside down fork would make sense again... But either way, I'd like to try a Manitou Dorado someday to test out if they are good for my style of riding or if I don't like them at all.
Who would have thought, with all the marketing, the tests, the long term rides, that huck to flat tests would reveal defects? I wonder if Pinkbike loves or hates these now?
3:14 can someone explain why the head tube angle is so slack 😂😂
can never have enough huck to flat ❤😊
my eyecandy playlist in one video 😋😩😩😩😋
That was cool, but, from now on you should have the guys were a three-piece suit!
Love the huck to flat but would really be intrigued by a huck to flat to rebound! Just to see which brands pogo and which dont🤷🏾♂️
IMO it depends mostly on the rebound setting, not the brand.
@@piast99 ultimately thats true but it also depends on kinematics for different brands also different brand suspensions have different valving to go along with the different brand frames🤷🏾♂️
You can easily adjust the rebound.
You can't easily adjust the overall stiffness of the structure or geometry.
They focused on the important area in this video.
So I wasn’t imagining things - hardly any field tests this year.
Why are the seats out of position?
the yeti sb 165 looks the smoothest
Main takeaway: don't buy carbon cranks.
@6:31 OUCH
Faltou a transition smuggler 2023 !
What’s with the handlebars flexing on the Mondraker at 1:50 ?😮
I think some flex is wanted. Aircraft wings flex a lot. Flex ensures it doesn't snap so easily.
That's another point for me to wax that chain. Not that I bottom out that often but when that chain literally digs in the ground you're fkd if that's full of oils.
*It's pretty satisfying to see both my bikes didn't split in half. Thanks pinkbike for the assurance 😂
It appears that the vertical shock mounted systems lack progression and this causes the bike to almost fold . As the rear tyre travels through its arc quicker this results in the head tube angle becoming slacker and therefore flexing before the front suspension moves through its travel. With flexing you have stiction. It's seems the more horizontal shock placement designs have more progression and this in turn let's the front suspension compress before flexion thus increases the efficiency of the shocks in unison. Just saying..
En la gran mayoría cuando el amortiguador delantera tiene mucho movimiento, noto que el rider usa mucho el freno delantero ( marketing de que paga poco )
😂… no sera que esta usando un poco el freno para usar todo el recorrido que es el fin de estos videos … 😂… TODAS las orquillas flexionan así …
At 06:29 what name cranks are those??
Praxis Works
@@andrewsandalov1033 Thank you for letting me dodge the bullet
1 lonely bike that decided it was a good idea to have the whole crank set on the swing arm 😅
Seeing that carbon crank explode was sketchy. Aside from that would be great if they didn’t hit the brakes to avoid the suspension bob in both front and back.
Funny Not One Knolly ......
was the crank arm supposed to break at 6:30? But seriously, while cool, is anyone learning anything from this, I'm just curious.
4:56 Canyon Stoic
the last bike was named wrong..
Front-Braking immediately on landing makes the front wheel to have a jerky bottom-out to release action 🤔
PLS upload the videos at 60FPS
The last bike shown is not labeled correctly
rip your knees 😂
Last one is a Pole, not an Ibis
Cranks of the specialized crack like plastic
😊
Idk, but I don't think that last one was an ibis
06:29 Praxis Carbon Crank?...
Looks like it.
The last one aint no ibis
First! ( taking into account every other comment is a bot (LMOA)).
I hate knowing how much handlebars flex.
And watching chains slap the ground is freaky.
I think some flex is wanted. Aircraft wings flex a lot. Flex ensures it doesn't snap so easily.
@@FIGHTTHECABLE I know right! And that freaks me out too! 😳🤷🏻♂️
That is a pole not an ibis Hd6
Nah did anyone noticed his tires we're flat in the thumbnail?
noo... marin but not nukeproof scout
6:28 ногу сломал?😮
wow... Bikes are floppy.
There is way too much flex in most of these bikes
Why does noone talk about Rose Bikes?
Left side of bike, right foot forward. Right side of bike, left foot forward. 🙄
🫡respect+
What is there to watch here? Am I missing something obvious?
its just for people to geek out , we will just skip to the bike we own and watch how it performs in slomo
@@awfully.averageother people will have a broader interest. Comparing the geometry, suspension design or lack thereof, basic intent of the bike, etc
@@procatprocat9647 you're right , i was just describing myself
@@procatprocat9647 I see what you mean . But you would get a better idea looking at the spring rate chart from manufacturer than this video. I also wonder how the suspension is compressed so much? I mean are they running high sag like 40 % to bottom out so easily ? You should be doing 12-20ft drops to bottom if suspension is set right
@Zenpedaler spring rates and damping can be changed.
What's of real interest is how fork angle affects the quality of the stroke and the deflection of the overall structure.
That's what upsets a rider.
As a professional Engineer, these comparisons are like bicycle porn. Try slowing them down even further for more detail. Running 2 videos next to each other is also fascinating
Grim donut....what a joke. good luck on hi jumps. bye bye fork
Soooo boring....
You guys need to do this with a banshee morphine. I want to watch the ground flex.
6:30 !!!!!
