Yeah sorry I brought it up
And a direct link here too. I really hope DoubleCrownAddict doesn't see it.
Hopefully, something novel like going down without needing rider weight. If it is just another post, it will be disappointing.
0 play weather extended or retracted, light, compact, easy to FULLY service would be great to see and if reasonably priced I’d probably consider it over the latest One Up perhaps
To match the fork
Milyard racing or Hover shock. What would win?
We will see about the dropper post but their prototype dropper lever had a really cool design and how it integrated the cable tension adjustment.
Reasonably priced… it’s Intend. Love their stuff, but none of it was reasonably priced so far. Even if the price is justified through production volume/company size etc.
However, I am curious, too, what Cornelius came up with…
On the other hand, compared to large players, it's not really unreasonably priced. It's not much more expensive than what Fox charges for their top of the line products in many cases. But it is a lot more niche.
Even if he does see it, he's been suspended alongside SaucyCheese so he can't say much of anything.
I think that Cornelius has completely outclassed Fox in the Upsidedown fork space. Options, quality, weight, price, reliability, performance, etc. Intend wins on every aspect.
What the Podium did for me, is make me really interested in the Intend...
I mean, everything seems reasonably priced to me
Context is important
Cranks are beautifully machined and 280€
A set of gx cranks around 100€ online, mass produced vs machined and hard anodized in Germany by a SMALL company,
The shock is 1100, comes custom tuned, a Fox X2 blows and retails around the 800€
Same goes with the forks
1650€ for a flash with perfect bushings and all and it’s almost the same for a fox 38 x2, again mass produced in Asia vs something from a tiny company in Germany.
Not cheap, but for what it is I’d say reasonably priced
genuine question, how hard is it to get support for intend n NA? either full service or parts for DIY? It always scared me off of niche Euro based product. I've been more likely to consider Push, simply because they are this side of the ocean.
Actofive charges 400 eur for cranks that are heavier than GX cranks. And the two piece glued cranks are no longer available (I wonder if it was the price or delaminating that killed them).
The price for those was very very high if I recall correctly
So probably that, although the Garbaruk are similar construction and like half the price or so
Actofive was 800 msrp.
Check out the Preston Petty No-Dive, from decades ago folks:
There were quite a few variations of Torque Arm Anti Dive set ups tried in Motorcycling - predominantly Road Racing, plus, a some hydraulic set ups - a few of which reached production Motorcycle models.
I've a couple of Preston's No-Dives, somewhere in my workshop, along with a few of his Fenders / Mudguards and his Headlights.
All of the Anti Dive systems basically 'disappeared'.
FWIW, modern F1 cars have quite a bit of anti-dive geometry in the front and anti-squat geometry in the rear, preventing the car from pitching back and forth during braking and accelerating to keep the aero platform (the underbody) as stable as possible and thus the downforce as consistent as possible.
The result of this is a lot less feedback to the driver (either way you cut it, any kind of movement or lean is a feedback on what the vehicle is doing) and some teams had and have a lot of problems with their drivers not being confident int he car and sometimes locking up the fronts very easily. Could some of this also apply to anti-dive setups for motorbikes and bicycles? So besides bringing some good stuff also bringing with them negatives?

Starting to make me question if we've been trolled and it's an e-bike...
I would love to ride this. You could make your fork soooo sensitive to small bumps and not have to worry about diving deep in stroke on steep loamy downhills when dragging front brake. The negative would be, how stiff does it resist when on the brakes, would it turn into a rigid fork? Always pros and cons...
F1 (and other highly aero dependent motorsports cars) are not a great example of suspension kinematics that will directly apply. This is especially true in the current ground effect aero era of F1 as a lot of the performance aspects of the car are in order to maintain a floor/diffusor distance to the pavement. That is so incredibly impactful of the performance of the current cars within the rule set, that it becomes the primary thing you optimize for, over and above mechanical grip. You'd see slightly more similarities with motorsports engineering with lower power cars without significant aero that are laterally traction limited (not being aero dependent makes this last qualification redundant).
In addition to that, the biggest differentiator between cars and motorcycles is really the tire contact patch surface area. This is obviously impactful under mechanical grip cornering from a design/technical data perspective. From the driver's perspective, the most impactful thing is the amount of braking grip that can be generated. If you've ever been on a street motorcycle and tried to stop as fast as the car in front of you, this may resonate.
Mountain bikes are a strange dynamic. With shifts/limits in traction and mechanical grip, and the fact that the payload out weighs the vehicle by so much and is incredibly dynamic, it is it's own beast of an engineering challenge.
I would say that is pretty consistent with how I felt riding the Trust fork - I felt much more disconnected from the front wheel so it was hard to tell where in the travel I was (without looking at the data) but it always seemed to have much more consistent grip, especially pushing in to turns. Unfortunately there was less warning when that grip ran out, so it was a strange catch 22 that encouraged you to push harder but took that away without much notice!
Since someone else brought up f1 - I was going to say (mostly joking) someone should do a Williams FW14b style (actual) active suspension that raises and lowers the suspension at each end - not altering with the spring or damper, just increasing and decreasing the length with a moog valve or some other actuator to maintain a more level chassis under braking, relative to the amount of deceleration. Only about and inch up or down each way, but considering raising the bars 10mm makes quite big difference it wouldn't need much
*edit - kind of like the bionicon or maybe Kona magic link
Interesting motor and battery placement on this ebike frame
That seems to be the Lapierre GLP4
In my opinion it's just a regular Lapierre GLP3 without the plastic cover (probably for better cooling/heat dissipation) ?
Vincent Ledieu is working for Michelin, I don't think he is involved in Lapierre bikes development.
That, is something Entirely different to a brake torque arm.
The Ribi Quadrilateral.
Designed by Valentino Ribi in the 70s. So much more than a 'traditional' Leading Link front end!
Tested - in part, - by Roger Decoster - He even did a few GPs on VRs original steel , twin shocked prototypes.
RD, persuaded Honda to buy the design / hire VR.
And, they went hog wild on it - getting to the Single Shocked version in around 1982 :
They never went much past that.
Just another design bought by a massive company, and , ultimately shelved. Though, quite a few other (small) companies, such as Cheney, made their versions of them:
And, many other enthusiasts have made their own,
Don't get me wrong, I'm quite the fan of the Ribi Quadrilateral - and, 'Funny Front Ends' in general. Made a few myself, liked them, but, still use those "Engineering Abominations" = Telescopic Forks. Though, I will be putting on my version of a leading link / Ribi front end on a 2t /4t hybrid I intend to use in Vintage and Veteran racing.
But, there's an enormous amount of pivots / bearings, even with the single shock Works Honda version pictured above - I think at the very least, with that Single Shocked version, 18. That's a Lot of wear points, and 'slop' issues to deal with. Hey, go into a MC store, and check the rear end on a linkaged MXer / Offroader - well, any type of bike . You'll probably find a bit of linkage slop, on a fair few of the brand new bikes in the store.
Heck, even a brand new PDS system can have it - even with the very best bearings available. I changed my linkaged 500 to PDS (because I love the PDS system with an Ohlins TTX shock, in my riding environment, and, I Can, being a 'maker' of 'things') and even that has a bit of 'slop'.
Something of note : a steering head mounted Linkage system, also has a hell of a lot of 'stuff', out from the pivot point, far more so than Triple Clamps and Telescopic forks. And that, brings it's own problems.
It's been an oft said thing, by Engineers when it comes to the non acceptance of their 'Funny Front Ends ' - they need the people that have been riding on Telescopic Front Ends, to die off, so their 'solutions' will become the norm ............
They're not doing a 4 unfortunately. The glp3 is a real hidden gem, best riding e bike ever made but I think they're only going forward with regular overvolts now the E-EDR is gone.
I know and wrote why F1 cars have antidive and antisquat, I fully understand it. The point I was trying to make is how it affects the driver and the confidence he (she) has, not the effects on driving/riding dynamics.
As the last few pages have shown, there have been A LOT of anti-dive front end solutions in MTB alone, let alone motor bikes. If it actually gave a meaningful advantage without any or at least without big drawbacks, they would for sure be the norm at least in high end racing if not general riding too. But they haven't. There has to be a reason for that and that reason can not be only the 'looks'. Even more so, looks can quickly be turned around if the guy on a weird thing starts winning everything - everybody will want that.
@TheSuspensionLabNZ touched on the issues with the Trust, @bearorso gives some good points with pivot slop (could be solved woth some preload, but that will add friction and thus harshness), etc. Sure, MTBs are not the same as MX bikes, bikes in general are not the same as cars, but all these tries at basically the same thing and all of them failing have to have a reason behind them? THAT's the thing I was trying to point out.
That's a GLP3 with the AVS motor protection: https://www.avs-racing.com/components/com_jshopping/files/img_products/Lapierre-GLP3-Sabot-aluminium-3.jpg
Have a few friends that own that bike and love it, frame is quite fragile though, a crash can easily lead to frame damage. No Bosch gen 5 version so far.
What about that post makes you think it's an e-bike?
