Understanding Suspension Layouts | Single-Pivot, Horst Link, Dual-Link & More Explained!

[@gmbntech]

How much travel does your bike have? Have you tried many different suspension platforms?

[@Orech9]

I have XC hardtail :D so 100mm in front :D and i love it.

[@simonm1447]

I ride a hardtail too, however the video was very informative and interesting. Good content.

[@WorkLessRideMore]

My ripmo af is DW link 148mm rear travel and my Tues is virtual 4 bar (V4L) 200mm

[@joshuaallswang8016]

My Gen 5 Trek Fuel ex is 130mm in the rear w/ the ABP suspension. My XC race hardtail has 0 travel in the rear. Both are a blast to ride in the given terrain.

[@lucideuphoria7092]

have a 150mm GT i drive single pivot with isolated BB (force LE 2013), a faux bar (linkage driven single pivot) merida 140mm from 2010 and a 2019 GT force 150mm four bar linkage.

[@bike314]

This is the kind of content that I love. Clearly a lot of work went into this video. It would be cool to have a follow-up video on the advantages/disadvantages of each design

[@mrvwbug4423]

In general. single pivot has very consistent performance, but can't separate pedaling or braking forces as well as other designs and is the least efficient pedaling. DW link has incredible pedaling performance, and is flat out the most efficient pedaling design, its high anti-squat however can cause it to have poor small bump compliance and less traction through rough stuff. VPP is similar to DW link, but trades some pedaling efficiency for better traction and small bump compliance. Horst link is the king of small bump compliance and traction, but the tradeoff is less pedaling efficiency, though it does still pedal more efficiently than single pivot, and a Horst bike will have tenacious traction on tech climbs. The traction and generally robust design is why Horst link is what is typically found on enduro bikes and a lot of DH bikes.

[@mrvwbug4423]

There are also variations on the 4 basic designs. Canfield Balance Formula (used on Canfield and Revel bikes) is a variation of DW link (twin link with co-rotating links) but the main pivot is forward of the BB, which produces even more efficient pedaling and also incredible traction, the tradeoff is CBF designs tend to be fairly linear in terms of their leverage curve. Rocky Mountain's LC2R suspension which has recently been revived on the new Altitude is a VPP (twin link with counter-rotating links) variant where the main pivot is concentric with the BB. Giant's Maestro link, is so much of a carbon copy of DW link that they were sued by Dave Weagle (Giant won the suit), they put the main pivot on the lower shock mount where standard DW link puts the main pivot on the seat tube.

[@bike314]

@@mrvwbug4423 Maybe I'm remembering incorrectly, but aren't most xc race bikes single pivots? I would think that style of bike would want good pedalling efficiency

Finally a video explaining in pretty much just the right amount of detail all the suspension designs. Doing the god's work GMBN! I've ridden a Giant Reign with their Maestro link, a Commencal Meta TR and absolutely hated it, and a specialized stumpy evo, which I haven't got much chance of riding it at all yet. So far the Giant has been my favourite, it was just so simple and is quite tolerant in terms of shock set up. I just got into MTB when I got the Giant and didn't know or bothered with shock setting at all. So I left everything in the middle and that bike felt really good already. Absolutely loved that bike. Then the META TR. For some reason the suspension just didn't work. My feet get bounced off the pedal every time I go near a descent, be it a set of stairs or a trail. I don't know if it was the high engagement hub that affected how the suspension felt (pedal kickback), but apparently there were a ton of anti squat to a point it just doesn't want to compress at all. I've tried air and coil, and different set ups to no avail. So I decided to get rid of it and bought a stumpy evo and see what the fuss is all about. Must say it is sooooo much better than that of the META TR and the bike overall just rides amazing. The Horst link suspension feels a lot more supportive, tho, and not as perhaps supple as I remembered the Giant to be. But then again, I need to spend more time with the stumpy.

[@jpfidalgo7]

Great video Anna and GMBN Tech team! I always wanted to understand this better, but never quite found anything that isn't full blown marketing for one brand. Thank you! I quite like the old Giant NRS system (horst link if I learned well? 😅), but I like to change the recommended pressure settings. By the manual, negative chamber pressure should be 5 PSI regardless of positive chamber pressure with the original RS SID (Dual Air or XC or Race) that had independently adjustable chambers. I tried to regulate positive chamber first to the recommended pressure, then put just 5PSI on the negative, then check SAG and adjust positive chamber accordingly, record positive chamber pressure, and then equalize negative chamber to the recorded positive chamber pressure for the bump sensitivity, or recorded positive chamber pressure -5 or -10 PSI for just slightly firmer suspension. Convoluted? Yes. Effective? Yes! I love that bike! (It also looks rather cool IMO)

[@gmbntech]

[@jonasolofnordlund]

The best video describing suspension designs that I have ever seen! Fantastic

[@smithandshortdogs]

By the 7 min mark I had noted two errors. In the original explanation, progressive is not described quite right: progressive is described as less movement in the shock for a given movement in wheel. This is true but the key fact is that the ratio of wheel movement to shock movement increases was, I feel glossed over. Secondly flex stays are not to provide additional bottom out protection. This is not what they are for: imagine the triangle a b c where a is the end of the seat stay near the seatpost, b is the rear axle and c is the pivot point generally near the bottom bracket. Under compression the points a and b are going to move at slightly different speeds relative to each other so one of the sides of the triangle has to change length. This obviously is going to be the length a to c. A little basic math(s) tells you this means the angles of the rear triangle have to change. The angles at a and c are fine... they are both set up as pivots (even on a single pivot design). The angle at b either needs a way to change, so you have to put in a bearing or bushing to allow the seat and chainstays to move relative to each other, or the stays need to bend. This is why most modern shorter travel bikes use flex stays... it allows the angles of the rear triangle to be "fudged". The reason you don't see it on long travel bikes is because the amount of fudging needed would require the rear triangle to be very flexy.

[@AnnaOnTheBike]

If 15mins of solid talking only resulted in me failing to explain two points adequately, then I’ll take that as a win. Cheers 😅

[@smithandshortdogs]

@@AnnaOnTheBike I always enjoy your videos, and virtually always learn something from them. No different here.

[@nounours2627]

At 3:30 concerning the explanation of progressive, it appears to me there's problem. It is said that during compression of the rear, the shock has less travel compared to the wheel that is was at the beginning. All the while concluding it produces a firmer suspension at the end of the travel... That simply cannot be. The smaller is the travel of the shock compared to the travel of the wheel, the shorter is its "lever"... hence the softer is the suspension. (think of it as lever arm if you prefer) I'm a road cyclist and know too few about MTB and their suspensions (that's why I was here). I cannot tell what's wrong : These layouts are designed the other way around and shock travels more at the end? It is simply designed to be softer at the end? (that would be strange) Shock are also progressive but overcompensate with firmness the mechanical progressive softness of these layouts? I don't know what is wrong but I know my physics and there is something looking wrong to me. One of the roles of the suspension is the transfer the work of the wheel to the shock absorber. It doesn't absorb energy, that's what the shock ABSORBER does. For a suspension, we could resume energy as vertical travel work. W = F x D Work = Force x Distance To keep it simple. For the same travel at the wheel, if you decrease the distance (travel) of the shock, you then decrease work (hence, force at the wheel, i.e. it's softer) or you have to increase the force of the shock to compensate the shorter travel of the shock. To be complete Since work is transfer from wheel to shock we could present it this way F(w) x D(w) = W = F(s) x D(s) Force(wheel) x Distance(wheel) = Work = Force(shock) x Distance(shock) F(w) x D(w) = F(s) x D(s) F(w) / F(s) = D(s) / D(w) Ratio of forces equals the inverse of the ratio of distances (travels) Could also be written as : ( F(w) / F(s) ) x D(w) = D(s) For a given wheel travel D(w), if you decrease the shock travel D(s) you either : decrease the force at the wheel F(w) (let the suspension be softer) or compensate the shorter travel of the shock D(s) by increasing the force of the shock F(s) (design a firmer shock). To have a firmer suspension, They overcompensate the shortening travel of the shock with an even more firmer shock. But it was wrong to say these layouts themselves makes the end of wheel travel firmer. Or The design of the progressiveness of the suspension is the other way around to increase the travel of the shock and not the opposite. But it was wrong to say the shock travels less at the end. But there is something looking wrong to me.

[@a.r.8850]

@@nounours2627 you are correct. simple leverage. less movement in the shock means more force on the shock, that would be degressive.

I'm still riding my old 2013 GT force le with the idrive single pivot setup. Was their last idrive bike. Nice 66 degree head angle and long top tube, but the seat tube is 72. If the seat tube angle was 2 degrees steeper I'd be set for life. It's running a 27.5 front with a 2.8 high roller ii and a 26 rear with a 2.6 nobby nic. Has super good pedaling, is nice and progressive but has a bit of brake jack. I have a newer GT force but always end up going back to the 2013 force out of habit. Just got the frame rebuilt and repainted. Ready to go another 10 years.

Big thumbs up. I have always wondered what the differences were in different suspension set ups. Would be interesting if there was a deep dive into the pros and cons of each suspension system / layout. Like for example I rarely see XC bikes use the dual suspension layout. So does that mean dual suspension is not as efficient for anti-squat? Since XC is more about climbing and speed.

Very nice video. Well done, well presented and very informative. Would love to see this continued. Maybe compare characteristics of Enduro, trail, xd bikes? Or more deeper dive how chain line and gear selected affect these characteristics - can have positive and negative impact, also can be used to tune suspension design on deularier bikes but set chain length on gearbox bikes has its own benefits

[@blurglide]

Flex stays are not for bottom out protection. It's just that in many four bar linkages, the pivot by the rear axle moves SO little that you can just rely on seatstay flex in place of that pivot. It's very similar to a faux-bar, but the pivot on the seatstay is just replaced with seatstay flex.

[@dit4963]

2:25 You confuse anti-rise with rise. When braking you have both rise (due to body movement) and anti-rise (dictated by the position of the IC and would happen irrespective of the body movement). Note: There is also brake jack, which is often confused with anti-rise, but is actually something else (dictated by the position of the brake caliper and it's movement relative to the brake rotor when the suspension moves. sometimes this is addressed with a floating caliper or the DW-link, but that doesn't address the anti-rise as it doesn't change the IC). Similarly when pedaling there is both squat (due to body movement) and anti-squat (dictated by the chain forces and IC). If you want to understand these correctly I recommend to watch andrextr's youtube channel.

[@funny_colandertv5352]

This video got me thinking about if using a progressive coil on a progressive virtual link is right call. Maybe should just open up the settings and just let the coil and link handle everything

[@mrvwbug4423]

Usually you want to use a progressive spring on a linear linkage and a linear spring on a progressive linkage. Progressive coils are mostly for bikes that are a little too linear to really run a coil like the Ibis Ripmo or anything with CBF suspension.

[@OldManAzeban]

Dave Weagle is the man!

[@mrvwbug4423]

A very very very litigious man. Now that his patents are expiring (except for DELTA and DW6) there can be a lot more variety in MTB suspension on the market. Prior to 2014 nearly everything was single pivot of some flavor as that was about the only design that wasn't infringing on one of Weagle's patents. Horst Leitner's link design had its patent expire in 2014 which caused the explosion in Horst link bikes afterwards. Santa Cruz held the patent on most VPP designs until last week, Rocky Mountain had to cease using LC2R in 2009 because of a patent dispute with Santa Cruz and they have mostly used Horst link since 2014. Few brands were willing to pay the extremely high licensing fees that Weagle demanded, pretty much just Ibis, Pivot, Evil and more recently Atherton.

[@mrvwbug4423]

So in many ways Weagle held back the development of MTB suspension by patenting and jealously guarding most of the viable designs, licensing his designs to only a few companies at a high price. One of the key reasons why bikes with Weagle suspension designs tend to be super expensive (i.e. Pivot, Ibis, Evil, Atherton). Specialized did the same with Horst link until the patent expired in 2014 as while it was designed by Horst Leitner, Specialized owned the patent.

[@parsarezaee6334]

[@Rickie-37]

Where would you place Yeti's switch infinity? I've owned over 30 mountain bikes in the past decade and absolutely love my Yeti the most as an all mountain bike. Takes the hits with a very progressive bottom out but climbs like a mountain goat. I love the Specialized Horst link for an enduro and DH bikes, seem to respond the way I want it to. Linkage single pivot is acceptable for Dh too. But I've never been a fan of the DW link or the handful of dual link designs I've tried. Currently I own two specialized, a yeti, and a Rocky Mountain.

The idler wheel is not so a longer chain can be used. It's to reroute the pedaling forces to a point that makes a relatively straight line from the frame to the cassette to minimize pedal kickback. You'll notice the idler is always in close proximity to the pivot.

Anyone got any feedback as to how the Propain feels to ride? I once tried a thought experiment as to how I might construct a suspension system, and, came up with something very similar to what Propain actually came out with a year or so later. My thought process was that it would be better to hang a rocker from above rather than pivoting over a link point and then use it to push down on the shock from above while pincering from the bottom. That way, you don't have to contend with the effects of an over centre lever situation which would potentially affect progressiveness throughout the stroke. The design interests me greatly, so, if any riders out there have any feedback it'ld be good to hear back!

I have heard very good things about this bike thats why I have chosen to buy it.

Is there anyone here who have met the same issue like me? Or is it normal with this bike and suspension? Maybe my air shock is not adjusted well… Thank you for the attention and your help.

Anybody figured out what the Pole Voima uses?

A twin pivot design unique to Pole. It's like a DW link and a Horst link had a love child.

Not twin link, dual link. I know in genetics twin doesn't always mean identical but in mechanical engineering it does. If the links aren't the same size and shape, they aren't twin link
