just imagine how fast it wouldve gone with headset cable routing !!!
lol
Based on the extra aerodynamic resistance that the loose cables provide. About 89.4ms
I would like to see Cathro ride this.
He do not like to ride this shit
It'd probably be the right size too
Why him over matt?
Fuckin Cathro NEEDS to swing a leg over this thing 🔥🔥🔥
PB race team should all ride Grim Donuts.
Since Pivot is making the frame, I'm not convinced until Bernard Kerr rides it. I want a Pinkbike/Bernard Kerr LSD collab.
Hella agreed 👍🏼
They need to fly it out to New Zealand! They really should tbh, it's great marketing.
The donut concept might actually have a good chance in the DH WC with some travel increases
My thoughts exactly. Need to get rid of the climbing gears and the dropper post.
the fox 40 is only 200mm or 190mm
More travel is gonna have it slamming the ground every 5 seconds
@@sorinvladu7021 I assume they mean the rear suspension travel
@@skatefreak666666 I assume they mean the rear suspension travel
Don't forget about adding a Keep It Straight (KIS) headset system to stay up to date. Plus the bike centre of gravity needs to be lower, so the rear shock and linkage needs to be UNDER the BB.
patented by canyon no?
@@calroberts5154 according to the interwebs it was patented by Syntace/Liteville, and "Canyon who helped with developing KIS integration has exclusivity for the new tech for a year".
So just in time for the next Grim Donut.
Also make it electric and with ABS brakes
How about testing it against some DH bikes ? that could be interesting
Very cool though !
This was my thought. I am curious if they ran a SC V10 down or something similar if it would have been at 2:15 as well or even faster.
This!
Love the shot at transition lmao
What was that about?
@@jeremyrobinette2563 headset cable routing 2:51
@@Jay_radd gotcha I seen the flash of a Transition but the Sentinel I had last year didn’t have that cable routing.
The design process of "push it too far and make it stupid, and then scale it back based on what we learned" on this has been interesting to see. I'm sure in many ways it's weird or less fun to ride, but cool to see that it definitely goes fast.
This approach was actually done in alpine skiing when carving skis came. It quickly went to extreme radius on the skis, and then it was slowly dialed back to find the sweet spot.
It is a good philosophy in many ways, also when it comes to technique, to try too far forward/rearward positions and so on, to really learn the boundaries of whatever sport your doing. Same with speed, you eventually need to try where the limit goes to get better.
But of course, when it comes to production bikes, where there is so much money invested in a line, and high competition between brands, it makes sense that chances are incremental. They Don dare stick out too much. But that's where prototype bikes for pro racers would have a place.
@@widkin you could almost say the same for powder skis, where the first inspiration was ski bindings on water skis. Definitely a step to the extreme.
I think companies found the perfect Geo years ago. They just slowly move bikes in that direction so we have to buy a new bike every few years lol.
Bingo, the mtb bike industry has turned into a money grabbing mobile phone formula.
Makes a lot of sense
The bike I’m currently on has a 445mm reach, 64.6° hta, a 77° sta, and 442mm chainstays. It came out in 2020. Aside from the standover and seat tube length being higher than what I’d prefer I’d call it perfect for an all mountain/enduro rig. I don’t think geo needs to keep going longer and slacker, but frame compliance and tech needs to be focused on instead. Making frames more reliable, reducing cost, etc.
@Phil B I miss the days when they did 4 to 6 year model cycles. Bikes alot cheaper back then. Still rocking my 2015 full suspension, not planning on upgrading as long as parts available and frame holds up.
You don't "have" to. That's a lie. They are not pointing a gun to your head forcing you to buy a new bike.
My bike is a decade old and it still rides like how it did when it was new. I did replace the cassette (wear and tear), shifter and rd, but the rest of the bike is the same.
This never gets old ;)
If I ever ride a bike like this, I’m gonna need a full face and 4 mouth guards
I'll need a jockstrap and a cup riding behind the seat.
I love the idea that something stupid turns out to actually be briliant. Keep it up!
Props to pivot for coorporating on this crazy project
You should run a mullet set up in the next one 29"/26"
Is "supermullet" already a thing?
I would like have seen the GD2 go first and then GD1 and then the control bike. This could have helped mitigate Matt getting used to conditions that day. But maybe he did a bunch of pre rides on the trail before doing test. Either way, this is super cool.
He holds a couple KOMs on cypress so I don't know how much he has to get used to the track
You guys should develop a ridiculous bike for the Black Snake trail in Val Di Sole. So many people were talking about that track being so gnarly it needs its own evolution of bike. You already have the grim donut. If you can build that with like 250mm travel F&R, maybe you can turn it into a flow trail?
No one mentioned the rock shox lyrik and Zeb vs the fox 40 in the time comparisons.
Was looking for this comment. Surely the 40 contributed to at least a few of those seconds. I know the track he is riding on Cypress and it's fast and rough. The price/damped feeling and confidence on steering you get versus a single crown would be a big difference on that terrain.
@@hobmarg not that big of a difference. more matters how suspension is set up and geometry of the bike
@@maxm2096 really? I haven't ridden two bikes back to back with identical setup besides a 40 and single crown, but I've owned multiple DH bikes and multiple long travel enduro, including a 170mm Fox 38 currently, and the dual crown always felt way more planted and confidence inspiring in fast rough stuff to me.
@@hobmarg it’s definitely gonna feel more planted and take big hits better but for the sake of going fast it’s less of a difference than the completely radical geometry is. that being said i still prefer my downhill bike for rough stuff.
Props to Pivot for being willing to engage in this.
Awesome video. I had a lot of fun watching Part 3 after all that time 🤩
Sick design, sick colorway, sick performance and result. PB should prototype this beast soon on future races.
To be honest, that was actually pretty convincing, the original was so extreme that you could see how it would be entirely track dependant like on some steep straight tracks it would be way better but equal performing or worse on the average track, having a regular bike in the testing was interesting bc it showed that the range makes up for the donut v1s slackness in cornering performance and ended up being just as good overall time wise
Watching the Sea Otter classic it's clear that the Grim needs to be a mullet with a 36 inch front wheel.
Hilarious intro top notch bro science, best PB video of the year
😁
The grim donut with 61 degrees headtube angle would be pog
Was the fork on the GD2 set to like 170mm? I wonder how much suspension performance can be attributed to have a 200mm dual crown fork on the front vs the GD1. Ofc it makes sense to have the dual crown. But just an interesting adjustment that was made from spec to spec.
How I feel moving from my OG xc hardtail to a 160mm status...
Lol yup!
Two years per episode ? No problem , long time 'Project Binky' follower , I can wait.
Bloody classic loved the hazy room at the start - must be the secret to the design
Wow! PB has gone where no bike company has gone. The design is so good, they have to dial the design back.
Geometron is not as extreme but close
“The design is so good they had to dial it back” - winning comment on this whole video. Good job sir
lol
Shots fired @ 2:51 :D !!!
Fricking Levy, good work Matt!
This is the future 🤯
This is super duper futer shit.
i think transition was taking notes when they made the spire, such a long slack beast..
If you have plans to make another one of these, you should make it a super mullet with 29-26 inch wheels for even more over the top-ness
That would be a Penny Farthing, not a mullet 😂
More likely to see a mullet with a 29 on the back and something even bigger 👀
Loved the invisible watch at the beginning
Levy’s acting deserves some sort of pinkbike award
There was no acting, he was actually smoking bud when his boss called
We’ve been waiting one whole pandemic for this update!
I've been waiting to see the Pivot Donut video.
I would’ve loved to see it compared to a dh bike as well, just because of the dual crown. Curious if that made a difference at all.
Get Bernard Kerr on the Grim
This bike actually looks awesome to me where the first one just looked rediculous
Yes duuuuuuuudes that was cool can't wait for the next episode!!!
That silhouette... it just cracks me up.
Thanks love laugh loam for getting pb to finally post this
And there never was another. Long Live The Grim Donut
Finally it is here. I’ve waited for so long for this video 😋
Try adding the BMB Raised Reverse stem
This is the single greatest video of all pinkibke history 🤣🤣🤣🤣🤣
Perfect bike to try canyons steering gizmo on
2:51 The editor really went in on Transition 💀
It's closer to 2:50.

OMGG I NEEDED ANOTHER GRIM DONUT VIDEO
Awesome, very well done.
While you guys are in there doing the headset cable routing, you should also add a K.I.S. system. Equally important in these modern times.
What a fun project, and this thing is just about a proper DH rig. Why did they put a Fox 40 on the front? I know it was set to 170mm, just curious why they didn't go with a Fox 38.
Next version: get with Pivot and make a new class of bike. 29 up front, 26 in the back and call it the 69er!!!!
I'm a bit weirded out by Beer's leg at 5:00
😅
Isn't it Matt that ate shit riding full speed down aline when the headtube of his boutique brand test bike snapped in half? Pretty bold of PB to have him try to set a good time on the OG grim donut lol .. glad you survived to tell the tale Matt
Imagine if bernard kerr would have had this bike in the 2022 dh season
You gotta make a steel hardtail version of this
@@jamesfynnhere6983 Cotic and Chromag are sweating nervously at the thought
If PB only did grim doughnuts videos, I would be happy.
lots of inside jokes on this one lmao
Head of to pivot for helping out 👍
Please do an EWS and DH Wordcup with that thing
Could you put a linkage into the headtube so that although the handlebars experience a normal feeling range of motion, the angle of the fork can be lessened/tightened up when cornering, thus, allowing you to gain from the redonculously steep head angle when riding the gnar but not have to suffer from it in the corners?
Also, the 1995/6 Kona XC bike approach to standover reach may need to be reigned in slightly 😅
How did they colour those spokes. Paint, Stickers?
I have enjoyed this series.
PB Racing has a new rig! Who needs a V10 when you can ride a GD2.0 w/ the PB link!
What a Mysterious trail!
Insane head angle anyway the dual crown play big on stability
You know it has to do a world cup dh race now aye!
i love this hobby do much
TR at 2:51 ....hilarious!
A water bottle mount inside the frame?! My 27.5 Firebird would like a word with you.
One thing i would like to see in the pinkbike grim donut game is changable bikes so you can have any bike you want. That would be really good and would make the game more fun. oh and more levels. @Pinkbike can you please add these features to the game.
I didn't notice the geometry, I only notiiced the doble crown fork on the Grim Doughnut, and a sigle crown one on the Norco. I guess I am old school.
Levy gives me lockpicking lawyer vibes with how he presents his voiceovers lol
I would love to take the old grim donut of your hands xD
what wall mounts are used near the end of the vid? nice to see the grim donut having an update.
Steadyracks
That was amazing 🔥🔥
Well this was a great surprise to wake up to. I’m 100% invested in any grim donut content.
Just please don’t do the April fools thing again this year.
Yes the return!!
I’m a simple man. I see grim donut, I hit like.
Yes! More Grim Donut!
God damn I want this, exactly like this.
It is perfect.
The flash of transition bikes, lol!
This is good stuff!😅
Levy is the heart and soul of pb.
how does the head tube cope with the slack angle,you would expect it to snap on first huck lol
better than christmas
PB giveaway. Donut rides.
You need to do prototype suspension. Like 12 inch travel
I would low-key purchase a grim donut
[Mike looks at an invisible wrist watch to tell us time] I want this technology instead!
It's a beauty!
What chainstay length did you use for this test? Why fox DPX, is the linkage super linear?
Unbelievable… at the morning I watched the video with Grim 1 😅
If only this lad hadn't spent all his money on tattoos... Would be raking it in by now after launching this beast to mass production...
The best!!
I'm all for media transparency Levy, I'm calling you out; that video took longer than 2 hours to produce! 🤣
Episode 4 coming early 2024!
