Video: We Really Examined Our Bike From The Future – The Grim Donut Half 2
THE GRIM DONUT 2
Half 2: The Proper Quantity of Silly
Phrases by Mike Levy
The Grim Donut wasn’t presupposed to work. It must be near-unrideable, a joke of a motorbike taken too far, and a punchline that took lengthy to achieve. However if you happen to’ve already watched the video, you may know that solely the final a part of that’s true. The Donut was supposed to be silly, however might it’s the correct quantity of silly?
Okay, superb, it won’t work in every single place, however its 57-degree head angle, 83-degree seat angle, and Winnebago-like wheelbase aren’t fairly so humorous now that we have executed timed testing with Yoann Barelli…
How’d We Get Right here?
The concept behind the Grim Donut was to skip the drawn-out strategy of manufacturers attending to the geometry we’ll clearly be utilizing in 2030. I imply, if that is the place we’re going, why do not we simply go there now? To do this, we regarded on the distinction between the numbers we utilized in 2010 and people we’re utilizing in the present day, then we merely utilized the distinction. To be sincere, I am unsure why nobody’s executed this earlier than.
We’re much better at misguided strategies than welding, although, so we reached out to Genio, a comparatively small however high-end Taiwanese manufacturing facility.
The 160mm-travel body is named ‘GF7-1-160A’ in Genio’s catalog, however after welding two downtubes collectively to get the required size and making use of our future-proofed geometry, it is higher often called the Grim Donut. If it’s worthwhile to catch up, here’s the first part of the story.
The one factor left to do was journey it, which brings us to the subsequent chapter within the Donut’s protracted life.
Timed Testing Aboard the Grim Donut
It isn’t that I wasn’t excited to journey the Donut, it is simply that I had some reservations. Positive, I’ve to get used to a new-to-me bike each few weeks, however I am often not questioning if the headtube will determine to take the break day. And the bikes often aren’t seven or eight levels slacker and a couple of foot nearer to the bottom. So yeah, I used to be apprehensive.
I survived, regardless of having extra pedal strikes in three-hundred-feet than I’ve during the last three-years, and the Donut’s headtube continues to be on responsibility to at the present time. But it surely was apparent that my cautious method and the less-than steep path have been, um, lower than ultimate for the geometry we’ll be utilizing in 2030. Fortunately, we all know a man who won’t even know what ‘cautious’ means in English…
It acquired critical as quickly as I handed the Donut over to Yoann Barelli. In spite of everything, it is one factor for me to exit and have some laughs whereas using our wacky bike, but it surely grew to become apparent that Barelli wasn’t joking round. Off the bike, sure. On the bike, not a lot. The Frenchman was inserting properly within the Enduro World Sequence just a few years in the past, and judging by his latest movies I am unsure he is slowed down one bit since.
The take a look at monitor was round two-minutes lengthy, stuffed with sharp rocks, steep slabs and, fortunately for the Donut, not a lot pedaling. It is also a path that Yoann was very aware of, having used it to guage his bikes through the years. That is vital as a result of it means he might take constant traces at a constant effort throughout the timed laps slightly than having to be taught the path. And talking of studying, Yoann spent all of some minutes getting used to the Donut, his solely modifications from my setup being to lift tire pressures a nip and to rotate the brake levers as much as near-level.
After posting a 2:09 aboard his personal bike, itself practically twenty-seconds faster than the present KOM, it was the Donut’s flip to go up in opposition to the Freelap clock. And if you happen to thought Yoann could be a bit apprehensive given its odd geometry and unfamiliar parts, his GoPro footage says in any other case…
Yoann went six-seconds faster aboard the Donut over the span of a brief, two-minute descent. On his first timed lap. Utilizing utterly unfamiliar brakes, tires, and cockpit. My response within the video is real – I did not assume the Donut could be a lot slower, however I actually did not anticipate Yoann to go quicker. So much quicker.
Is it a coincidence that the Donut is about six-degrees slacker than Yoann’s private bike and he additionally shaved about six-seconds off his time? Given the Donut’s rigorous improvement and groundbreaking method to selecting geometry, I would say there’s zero probability of that being the case.
Yoann clearly made the Donut work for him, however that may not imply it is smart as a day by day driver for these of us with no professional racing license. ”No, I do not assume so. As a race perspective, I believe sure. And I believe that perhaps this take a look at would possibly make manufacturers see a little bit out of the field, and if they need racers to be quicker, perhaps they must make correct bikes for the racers.”
”Would I journey this bike every single day? Completely not,” mentioned Yoann after his run on the Grim Donut. ”The best way it’s proper now, the geometry is not nice. If you pedal, you are going to hit them on the bottom. And it would not nook correctly, but it surely works once you go tremendous quick.” Having executed some tentative take a look at laps of my very own on the Donut, I can affirm that it is a handful once you’re not at ten-tenths. ”However on one thing like that,” he mentioned of the rocky, high-speed path, ”the place it is kinda quick with lengthy corners, you simply must be fairly centered on the bike and also you simply go for it!”
It is smart to listen to Barelli say that the Donut’s lengthy, slack, and maybe-a-bit-too-low geometry most closely fits eye-watering speeds, and there is no doubt that its overly-active suspension only helps that cause. Stability and traction equal velocity, and that is even more true when each are onerous to come back by.
“The EWS in Chile? This bike wins by a minute,” Yoann mentioned of the dusty, free South American occasion the place racers usually say they discover solely anti-grip.
What Do We Do Now?
What do the microwave, Submit-It notes, chocolate chip cookies, and the Grim Donut all have in frequent? They have been all lucky accidents. This was initially meant to be a two-part sequence and the joke was presupposed to be on us; the Donut was presupposed to be horrible and we have been presupposed to be taught some form of lesson. As a substitute, we might have stumbled onto one thing promising. Too promising too ignore.
So we’re gonna do the one factor we are able to, which is to start work on the subsequent Grim Donut prototype. Anticipated launch date: 2030.
