Forbidden DRUID: High Pivot with Idler Suspension Design REVIEW

[@Veil_Ants]

You have THE BEST suspension breakdown videos by far. I looove this stuff it's a shame you only have 5k subscribers.

[@TrailPOV]

Thanks very much. It's growing😀

[@HackJoward]

Hey man! Liked the video, good rundown of the bike! Just a couple of pointers from experience with this bike; having built a couple, you don’t need to buy two chains for most of the frame sizes, it’s only at the XL size that you need a whole chain, plus 3-4 links. Also, it’s a remarkably quiet bike, when built properly! Another interesting point is that there is the ability to access the inside of the DownTube via a small ‘hatch’ located by the BB! Enough room for storing a tube and some other spares in there, very neat!

[@TrailPOV]

That's good to know, thanks for the input. I remember when I upgraded my bike's drivetrain last time the chain only included about 4-5 more links than I needed so I just suspected that running over an idler would necessitate a super long chain....or two chains. Very cool to hear about the downtube access! I wonder why this wasn't highlighted more on the Forbidden website and other sites.

[@igethanxcmtb9437]

That was really informative, thanks so much! I like the new video design, it seems very professional and clean.

[@TrailPOV]

Glad you noticed! A lot of time was taken to put together a unique intro sequence. Always good to experiment :)

[@therealridedmc]

Having ridden a HSP for many years, I have to say you missed one significant con (IMO). That is - the rearward wheel trajectory results in a lengthening wheel base as the bike goes into it’s travel. While the idler location cancels out the lengthening if the chain, the lengthening of the wheel base does make the HSP feel less playful as it’s generally harder to jump, manual, and bunny hop than a FS bike with a traditional rear wheel trajectory. For some people this won’t be a big deal as the square edged bump compliance helps the bike go faster, and maintain better traction through rough chundery sections. It all depends how you like to ride I guess. Great video. Keep it up.

[@TrailPOV]

There have been a couple comments about this. Having not ridden the bike myself I didn't know if this would cause such issues, but seems like the lengthening chainstay does have a pronounced effect. Thanks for the input.

[@maxlaguda4232]

Hey, do you reckon you could make a video explaining what is ideal on a bike of a certain genre (trail, enduro, DH) then explain which linkage design is best suited for those characteristics?

[@TrailPOV]

Unfortunately there is no 'ideal' as everyone has different opinions on what they want their bike to feel like. I suspect if I made this video there would be tons of negative comments from everyone saying I'm wrong, for different reasons.

[@sergerasklad]

1:20 this basically means that in this system the antisquat is not affected by a gear at the cassette, because the chainring-to-pulley chain segment stays the same. nice benefit! by the way in the recent pinkbike review of a deviate highlander with the same layout (high pulley on a swingarm) they have a graph with different antisquat figures for different cogs on a cassette, wich clearly means that they used the cassette-to-pulley segment of a chain in their calculations (that would be correct if a pulley was mounted on a front triangle). I'm on your side with this one, just wanted to mention.

[@TrailPOV]

Thanks for the input. Everything that I read indicated this was the correct way to do it and it made sense to me in the end 👍

[@ericjoly96]

Can you share your resources? 3 years after posting this vid I still can't find a clear answer on chainline swingarm intersection for calculating anti squat on single swingarm high pivot idler bike. Recent models found in the online library from Linkage is giving me mixed answers.

I think it might be nice to have videos explaining in detail how anti-rise, anti-squat, leverage ratio, wheel path, chain growth are calculated, and to give examples of how it affects riding. I like your engineering approach to the suspension systems and the technical depth, that is pretty much unique in this channel.

[@TrailPOV]

Thanks for the feedback. Between the 'What is pedal kickback?' and the Scott Ransom video it should explain most of that.

[@mattschirle]

Excellent analysis! I'm also a big fan of this design. But one minor con you missed is the rearward axle path does still result much more chain growth on the lower portion of the chain between the derailleur and chainring than a conventional design. It's probably not a very significant problem, but it may add a little extra friction in the suspension from the clutch or increased wear on your derailleur.

[@TrailPOV]

Very slightly. The chainstay lengthening on the bottom is counteracted by the chain length shortening on the bottom as the wheel/cassette rotates backward relative to the swingarm under static compression

[@pgson8929]

Awesome effort. Would love a video on the Norco Range!

[@maxlaguda4232]

Just curious, what bike do you ride? Also, would you consider analysing different categories of bikes like downhill? Also great video as usual!

[@TrailPOV]

Thanks very much. I've got a Scott Genius LT from several years ago. I'm not against looking at other bike styles, but so far the voting has mostly led to enduro bikes because of their need for excellent pedaling AND downhill performance. Enduro bikes are so versatile that I find knowing what the engineers have focused on while compromising on other things is hugely beneficial.

[@klstrucker930419]

My suggestions for downhill bikes analysis are specialized demo 29(4 bar design, winner of 2019 UCI dh world cup), commencal supreme dh 29(Amaury Pierron won uci dh cup in 2017, 2018 and was 2nd 2019, single high pivot design with idler pulley) and GT fury(combines 4-bar design with idler pulley).

Hi there. Excelent video by the way. I would like to lear more about high pivots. Can you point me to some materials that you have used for force analysis? Trying to wrp my head around the anti-squat, and the way you present it here, I would say that it should be always the same, no matter which gear the bike is in. But the simulations in Linkage X3 proved me wrong. What am I missing? Thanks.

[@cascadiamtb5309]

Excellent reviews, glad to see someone breaking down the suspension geometry. Very cool! Loved this review. If you can, do a breakdown of the Deviate Highlander 150 and the new 2021 Cannondale Jekyll, both high-pivots.

I had the luck of testing one... They're actually super quite, the extra idler paired with the that e-thirteen chain tensioner makes everything tight. Plus it has hefty chain protection, incredible details to frame construction and finish. Superb mountain bike

[@ethank9635]

Do you think having a rearward axle path is that great? Even though it moves out of the way for impacts it also slams right back into them when returning... seems like an axle path that goes straight up would be ideal? Ik it is also good for adding stability by increasing wheel base tho. Thoughts 🤷‍♂️

[@StructureCycleworks]

Actually no, as in most cases you will be over and past the obstacle by the time the suspension decompresses. Also, the axle path is still more vertical than rearward. In any case, you'd have to hit a really badly timed sequence of squared-edged hits to get the kind of kickback you're concerned about, and this suspension would still be more aligned with the force vector of those hits (a desirable thing) than rears with more vertical axle paths.

[@TrailPOV]

Well said.

[@klstrucker930419]

Hi, I have a question regarding pedal kickback, that really confuses me: does it even matter when going fast down the hill? Once the rear wheel goes away from the sprocket the casette would simply rotate forward, as the wheel probably rotates even faster, therefore not causing any pedal kickback. Am I right? If that was true, all the discussion about chainless feeling wouldn't make any sense.

[@TrailPOV]

So you're not the first person to comment about this and I did some research a couple of weeks ago about this topic in particular. If you are rolling fast downhill I have been convinced enough that the pedal kickback would not be a big deal. However, if you are doing technical climbing at much slower speeds it still does come into play. But I'm open to others comments about this topic.

[@mattschirle]

@@TrailPOV I think this is correct and it is consistent with my experience riding a high chain growth bike for several years now (Intense Recluse). I only notice it while pedalling over chunk.

[@hummer694life]

you are only going to feel pedal kickback when pedaling... If you drop the rear of the bike, the pedals will counter rotate but the force is so small that you would never feel it.

[@klstrucker930419]

@@hummer694life Yes, that's clear, because the chain is under tension. But idler pulley is the most popular within DH bikes. Check world cup videos, they only pedal on flat, open sections. On the other hand we saw some riders winning after their chain snapped(gwin in Leogang, i think it was 2015?)

[@jcsuperstars1100]

I agree with klstrucker, no way the suspension would move faster than the coasting of the freehub and pull the chain. I mean who pedals while hitting a huge bump anyway?

It is hard to get a high pivot right but Forbidden have done it with the Druid. The only other high pivot I like (a lot) is the highly original Craftworks ENR.

[@enol8603]

Check out the Craftworks ENR. It's a high idler pulley design with the pulley position changing through the shock stroke. It's also a dw link type suspension design and has 5cm of rearward wheel path. Chain length required is exactly the length of a Sram 12 speed chain so no need to shorten or lengthen the chain.

[@TrailPOV]

Oh goodness that's a complicated setup!

[@hummer694life]

I'm not sure you really need a changing pulley... it's there to make the AS the same throughout the travel. Who needs high AS deep in the travel? More things to go wrong and make noise imo.

Really nicely explained, but I haven't cleared the thought about the forces from the chain that run through between the idler on the Swingarm and the High Pivot... anyways a review for the V2 Forbidden Suspension Design would be really interesting it seems, even if they are that similar, but thats what makes it as interesting I guess :)

[@TrailPOV]

Thanks for the feedback and suggestion. Happy trails!

[@tomdonaldson9203]

Fantastic video! Any idea what would happen if you removed the lower most linkage (connecting the swing arm to the shock driving link) in-place of a Horst-style pivot towards the rear axle?

[@tomdonaldson9203]

Similar to the Antidote Darkmatter or Devinci’s Wilson bikes I suppose

[@TrailPOV]

I'm not sure I completely understand. Any changes to the chainstay would change the leverage ratio with the shock but have no effect on the wheelpath as that's defined by the seatstay as it's a single pivot design.

[@seanrequiredfieldcannotbel1362]

Could you do the Druid V2? And/or the Deviate Highlander? I think the Deviate has far less friction in the system. I know I'm not a part of the Patreon, my apologies.

[@parolesdelego]

Hi great vid! Could you lead me to some article explaining why the force is transferred from the idler and the chainring and not the cassette and the idler? I can’t understand why that is. Thanks!

[@TrailPOV]

Thanks. I'll try to explain it without having to find and article that fully describes it: The pulley is mounted to the swingarm, so the only external force to the swingarm is between the idler and chainring. The forces between the idler and cassette are equal and opposite because they're on the same object and an object can't apply a force to itself and cause itself to move.

If building the frame up, how would it hold up with a coil shock with a progressive spring (love my Bomber Z1 on my hardtail and thinking about pairing it with a Bomer CR for a build)?

[@TrailPOV]

Other than a little extra weight, and assuming there's clearance for your particular shock, it should be all good

[@joeblack4026]

Well from what i heard from R&D @specilized. they say that anti rise above 100% or around it is actually not ideal as you lose traction. They say the sweetspot for going down is somewhere around 50 %

[@TrailPOV]

Each bike mfg definately has a different vision. Some prefer squishy bikes that absorb everything, others prefer firmer bikes so they can pop and lean into the bike without it absorbing their input.

[@ek8507]

@@TrailPOV but couldnt the sag point of certain bikes (perhaps not the druid) be above the rearmost point, which in turn doesnt allow the wheel to go up and over obstacles as easily as marketing suggests? or does that change when the bike is being ridden vs just being sat on?

@@ek8507 Now I see what you were referring to in your question. Yes some frames with a wheelpath that arcs forward early in the travel will have a more forward wheel trajectory from sag onward that might not be ideal.

[@shaywright8105]

Can you explain why the there’s not as much chain growth even though the wheel path goes rearward

[@TrailPOV]

Because the idler is right next to the pivot. So relative to the bottom bracket the rear axle is moving rearward, but relative to the high pivot is isn't moving rearward at all, and the idler compared with the bottom bracket is only moving a small amount

[@Phlizz]

Frankly? Most benefits of HP bikes come from gaining control over chain interferences with the idler pulley... thruth is: anti-squat, -rise, axle path, linkage ratio all work enormously well in a wide range of designs, actual pivot and virtual pivot placements. There are so many factors that put more value in favor of a good rear suspensions than the design itself, it’s almost obsolete which one you choose within the working parameters. Square edge compliance and remaining wheelbase sounds nice, but both also have a very ugly side to them as well. Speak of instantly changing COG or counter rotating forces on rear wheel. Since the determination of the single pivot sweet spot, a game changing design is yet to come.

[@TrailPOV]

Interesting food for thought

[@Phlizz]

shure there is no reason to better what is the status quo, but there is more marketing about those designs than actual benefits. My recommendation is: Always look at actual movement of rear wheel contact patch (the only data you will feel) matching movement of the shock through its travel (only data to determine shock response). You'll find how close those values are on any given design. It sounds weird, but anti-rise and anti-squad tend to be unrecognizable with a proper component spec and setup rather than the theoretical benefits or letdowns of the various designs. @@TrailPOV

Why is the character of this bike always described as planted, when suspension and geo numbers would point to poppy? Loved the numbers on the size M, but ride flat terrain where we have to create our own fun.

[@Jwmbike14]

Ge there. Just a heads up, your explanation for anti-squat with the chain idler on the rear triangle is still wrong. If what you said was true it would be constant for any gear, in reality it's more complex than that. There are two forces at play, chain ring to idler and idler to cassette.

[@TrailPOV]

While there are two forces, the one is an equal but opposite reaction force. Because the idler is connected to the swingarm it, the only force between the swingarm and front chainring is the vertical force. The horizontal force going between idler and cassette is an 'internal' force to that body
