Suspension Seat Post for MTB? Does this make it Dual Suspension? What are Suspension Posts good for? 

I've had a suspension seat post on my mountain bike for over ten years and the only way I'd take it off is to put on a new one. And as I get older the more my back appreciates it. It requires much less care than a full sus bike too.

Suspension seat posts are actually very common on gravel bikes. Just enough suspension to take smooth out some small bumps you are likely to encounter on gravel roads.

I put the PNW Coast dropper on my MTB - it's a dropper, but also has suspension. I like it!

There's uses for suspension seat posts, depending on the type of riding. But for XC or gravel riding on a hardtail, I could see someone preferring to go easy on their back rather than getting the exact correct pedaling geometry. Also, if someone has a problem with my seatpost or the colors on my bike, then that just tells me they're probably not a person I want to hang out with.

The PNW Coast dropper is the best of both, dropper and suspension. Less plush, so only takes the big hits, but it lets you keep your saddle ight correct while seated.

The whole thing about bright colors and noobs is ridiculous. So many bell ends got into MTB the last two years. Each to their own, and that goes for suspension seat posts.

Nothing's wrong with suspension seat posts, they're especially popular for touring It's suspension for your butt, but not for your legs and wheel - almost completely for comfort You can get suspension dropper posts by proper brands too!

I asked to do this years ago at my local shop and they looked at me like I was an alien. Judged so hard, don’t understand why more people don’t do this

The combo of plus size tires with the suspension dropper, it really smooths out the trails but nothing takes the place of FS.

It will have more contact with the ground with sus-seatpost. Because the bike will go up and compres the post which after that will push the back of the frame towar the ground decompresing the post. (If course not as much as rear suspesion but but better than nothing )

20 yrs ago I had the rockshox suspension post for Cannondale f800 and it was supposed to be the bomb at the time and honestly it worked great.

It does NOT make it a full suspension. You need suspension most when descending and when you descend you stand.

If the bicycle frame is not isolated from the rear axle, it is not a suspension frame. Just as Kevin said, it's about rear wheel contact. Suspension posts have limited function and different designs work better than others. Parallelogram pivots like the Cane Creek Thudbuster work the best. Telescoping posts have more stiction and the axis of post movement isn't on the same plane of travel as the rear wheel bump path. 20 years ago, I bought my first real mountain bike, a Raleigh M60 hardtail which came from the factory with a telescoping suspension post. I replaced it with a Rock Shox suspension post which worked marginally better. It took the sting out of bigger hits. I sold that bike to my dad's friend 18 years ago and he still has it with that Rock Shox post.

This started way back, I've seen a few 2000s late 90s bikes with suspension seat post.

I have the same Zoom suspension seat post, even with the exact same color. Yeah, it definitely brings some comfort but not enough. I am going for a double spring loaded seat for more comfortable ride along with this seat post.

I think that this might be good for an old guy like me riding a green trail, but for a more aggressive trail I would probably rather have a full suspension….great video Kev!

It's one of those things you don't think it makes a difference until you take it off.

Awesome...your doing what im attemtping to do..which is take the base of what they gave us..and turn it into something worthy of rugged trails

There is nothing wrong with this, the more comfortable you are the better

A lot of bike packers and tourers swear by the Cane Creek Thudbuster. The new one is ok with the single elastomer, but the old ones with two elastomers were pretty crap.

Good for people with back problem on a hardtail, maybe even on touring hardtail bikes on dirt roads as too much vibration can cause more fatigue.

Technically it's a matter of un-sprung wieght. That's the weight of the wheel, axel, and forks(on the front) and swing arm for the rear. A seat post is the ultimate in too much weight that is un-sprung since only the seat itself is "sprung" weight. There's no shame in comfort or health. I've had back surgery in h.s. and @sixty seven I'm almost ready for a big fat Walmart seat and the maximum drop post they make and full suspension too.

Ok for comfort, but not for mtb, as a proper attack position puts you out of the seat. Also, one of the main purposes of suspension is to increase traction and keep wheels planted.

I got a question, on the Schwinn boundary can you upgrade to front sprocket because it looks like if you go up in size it will hit the frame

What if you add a suspension seatpost to a dual suspension mtb? Would that make it a triple suspension bike? lol I do remember mtbikers back in the 90's on their 26ers with suspension seatposts. I don't think it's weird. I added a PNW suspension dropper post to my wife's Diamondback Lux 2. It adds a little bit of shock absorption.

I have suspension seat post and they make a bike ride more comfortable

Have you tried a PNW Coast, dropper and suspension in one, plus adjustable so might reduce the bobb side effect?

I used to have suspension seatposts on my hardtails in the late 90's to early 00's. It's pretty good for hard packs and mildly rough roads which really helps in schock absorption even though most of the seatposts that I used only had about 25-30mm of travel.

I don't really ride trails any more so may I be forgiven for breaking this taboo years ago? I must confess that my old MTB is now a converted e-bike. Pre E conversion and age I could see using a suspension post on trails since I was always standing on the pedals, either pumping up hills or flying downhill. The suspension seatpost might be of use if you want to sit while coasting but otherwise I'd think it's not a pro or con on trails. I prefer the suspension posts that arc back rather than piston up & down. I don't know if that makes a difference to trail riding but it's way more natural feeling in other riding.

I use the PNW Coast on my hardtail. It’s a suspension dropper post. I love it for riding around town and on easy trails. If things get bumpy, it’s a dropper post. It gets out of the way really easy!

I like these! I got 2 of them, one for my xtrada 5 and 1 for my taff comp.

I feel like for the price, I would have spent a little bit more to get the Tannus Tubeless Armor on the rear of a hardtail to soften the bumps among other benefits.

no it's not full suspension, and the seatpost you did use simply goes up and down. it isn't designed to move back and forth as well as up and down, if you want a more useful suspension seatpost get the SR Suntour NCX

Suspension posts were actually very common in MTB during the 90's; had one on my hardtail. Most popular ones were Cane Creek Thudbuster, USE XCR, even RockShox made a suspension post! I believe they largely fell out of favor because tires got bigger, weight, and they really didn't do too much for technical riding. I'm surprised they have not made a comeback on gravel bikes.

imagine a dual suspension fat tire bike with suspension seatpost and suspension stem. quad fat suspension. my pnw coast is on a hardtail ebike it's awesome!

USE Alien XCR shokpost on my MTB for years. Same difference.

Whatever you like ....it's not my bike.....that's how I feel.......same thing as the old spring seats......biking is biking......and ppl need to chill out......and I have red water bottle ...and red pedals.....and red rickshox fender......but I'm not a newb. I've been mountain biking for about 10 years.....and all my bikes I've done the red

0:35 Kev: “...and basically the only thing left is the factory frame...” Well, I just had to see if that was true, so I did a quick once over of Project Comp V2, so I scoured it! Apparently, you did miss a couple of things, the disk rotors still show the telltale Schwinn logo, so those are still stock, and the derailleur hanger is stock too, as far as I know. I’m a big fan of the channel, so I’m not trying to pick you to pieces or hate, but I just had to check, ya know! I was going to say that then headset and BB bearings are stock, but I’m almost positive you replaced the BB bearings, and I think you used a Jessica branded headset for the tapered X-Fusion fork? Nice video, I agree, a suspension seat post does not make a hard tail “full suspension”. The “dual suspension” thing is a stretch, and it’s misleading, I can see some companies using that to their advantage. As you said, a suspension seat post and a proper rear suspension setup are COMPLETELY different. I wouldn’t run a suspension seat post on my hard tail, as I don’t ride rough stuff, and I don’t need extra weight or complexity, and plus it probably wouldn’t work super well for me (I probably wouldn’t have enough Nass to really use it’s full potential). 6:28 That shot man...I’m not even going to ask how you got that angle! The things YTers do for their viewers...🤣🤣

I put these on all of my bikes. Makes a huge difference on the trail for the small bumps and roots especially. Bikes are Trek excaliber 4, Giant tempt liv and womens schwinn al comp . Me, Wife and Daughter...ride on...

I've used a suspension seatpost since the 90s on my hardtail mountain bikes. If set up with a little bit of sag they will actually not only protect your back and rear end from shop but they will smooth out your pedal stroke as many people have a little bit of bounce in their pedal stroke. This type of setup will ride with you much like the old beam B used to do when those were in fashion. I've always been a fan and just recently installed one on a new Trek Marlin that I transferred parts over from a frame that failed. I also do have a full suspension Trek top Fuel so I do have an understanding of the differences between these two types of setups. I don't know why anyone wouldn't use one of these on a hardtail of any kind whether it be a gravel bike or a road bike that people use for centuries. And if anyone thinks that it's not for the serious mountain biker, I've won a couple of races with this setup. Not because of it but because I think it's a significant upgrade to any high-end hardtail

It's a stealthy mod. If you're afraid of being judged, simply don't tell anyone. It will never cross their mind to check, because they don't expect to see one. And you can ride with a little extra comfort. If you sometimes do longer rides on that same MTB, and not just a 10 minute challenge trail and then sit down for 3 hours of beer, it'll help you not feel so sore.

hey Kev, how long does it take to bed in cable disk brakes like om the "ladies" Al Comp?

2:30 Alright, whoever is confused about this being a suspension simply does not understand what the purpose of a suspension is. A suspension system is designed with ONE purpose in mind and that is to keep the wheels in contact with the ground. That is what a suspension does. It is not for comfort. It is not for relieving you of the bumps and jolts of riding on an uneven surface. They tend to do that, but as a side effect and NOT the main purpose. The way they work, mostly, is when the vehicle comes into a force which knocks the mass upwards, the downward force of the suspension (usually a spring) keeps the wheel firmly planted on the ground. They have dampening (the shock part) to limit the action of the spring.

Anything that helps reduce stress on the back, balls and butt is an upgrade in my opinion. If anyone gave me flack for having one, I could honestly care less. Btw, I'm currently looking at different reviews because I'm wanting to purchase one for myself here soon. I'm in my mid-40's and just got a great deal on a 2014 Specialized Crossroads bike (I think it's classified as a Hybrid Bike). Yeah... it's a 2014, but it looks like it came out of a time capsule! The guy I purchased it from initially got it with hopes he'd have something to ride when his Son would come home from college with his bike to visit. Unfortunately for him, after going out riding a few times, he realized the bike was way too big for him. After that, it had been hanging in his garage until he decided to put it up for sale. All thing's considered, I think $140 for the bike & a new 2-bike hitch mount was a great deal! As you can tell by this long comment, I'm really stoked to get back into cycling again. When I was actively riding (youth until late-20's), I went from BMX to Mountain Biking. Shortly after becoming a Father, and a series of back, neck and shoulder injuries... I quit riding. Recently I quit smoking, and I'm seriously trying to slowly get back into shape... but I'm still going to have me a beer every once and a while. Wishing you all the best. New subscriber here. Here's to you and suspension seat post's! Cheer's 😎👍🍻

You have to color coordinate components.

As always, your posts are entertaining and informative. Thanks for taking the time to share your messing around with bikes. I'm in agreement with most, if not all, of your views on what and how you do "the bike thing".

Personalized colors on a bike equals “noob”? HA that’s hilarious. I guess everyone I see on the local trails including myself are major NOOBS! Nice video kev, I’ve seen these pop up recently on my suggestions from Amazon. Might. E a good option for someone who doesn’t use a dropper and keeps their saddle height pretty high. Being a short guy these are a no for me.

PostModern anyone? Old Skool!

When you sit on a suspension seat post like this one, it messes up with your proper knee extension unless you adjust it so stiffly, that you won't really notice any diff when riding. I see a lot of improper knee extensions when it comes to e bikes.

I've bought and still have the Mongoose A series mountain bike a50r from the 1990's it's got front suspension and I wanted to do hardtail because when your power pumping you don't lose motivation in frame flex with the rear suspension. This same bike came with with a factory suspension seatpost and let me tell you its amazing, it doesn't travel like you might think it would but only enough to do its job but never an issue with changing the seat height variance to the crank. I've also got the Mongoose D70r newer model with no suspension seat post but it's got full dampening suspension on the rear. Flexible rear suspension helps considerably going downhill Xtreme trails but on more flat ground it seemed a little more flexible than I liked that's why I went with the hardtail as well for your average off-road traveling.

I dream of owning an evil wreckoning and I will never be able to just throw 8 k at a mountain bike. Too many people relying on me for me to splurge on myself like that. I plan on getting back into mountain biking soon. I think that I'm going to buy this schwinn and upgrade it with time. It won't be a evil wreckoning but I think that I can make it into something nice. So I enjoy videos I use them as inspiration and to help keep my passion alive while I'm not riding

I am with you, it not full suspension.

If you get a full suspension bike and add one of these posts, does it become tri-suspension? (just kidding) I've used suspension seat posts in the past just for comfort. Regarding bike colors, anyone that thinks a bright bike or pedals is a bike newb is an idiot. My bike is very bright and I've been riding since the mid 1970's. To me, it's about being seen for safety reasons. The idiots are the ones with everything dark (clothes, bikes, etc)that blend in and can't be seen. Kind of like the potential Darwin award winners that wear dark clothes while walking on roads at night.

They seem great for hardtail ebikes! MTB people probably want a dropper though.

I’ve been running the Cane Creek Thudbuster (old style) on my hardtail for several years now. Age was taking its toll on me and my local trails were startling to beat me up too much. This was a perfect fix. Designs like the Thudbuster that are based on a parallelogram work better, no binding like the telescoping ones so they are much more plush. Once you find the right seat height, the changing leg extension isn’t a problem.

I recently got the PNW Coaster suspension dropper post for my hardtail. At 40 mm travel, I wouldn't call it real suspension 🤣 my butt does feel luxurious and cush though.

Google says 44mm = about 1.57 inches at my age I don't think that would be a big deal for me.well done sir 👍. Be careful with some of those camera angles. LOL

Nobody thinks a seat post spring mimics any suspension NEVERTHELESS, that is a sweet looking build

I think we put what we want on our bikes its our bike. If someone thinks some one is a newb cuz they like color on there bike is just annoying n newbs keep mtb popular!

My 2022 Giant Trance X3 is painted in good grey and glossy black but all the accents are purple ..... not all the accent are of the same hue , not even those of the same brand ...... Go figure. Lol.

Kev central you know some Walmart bikes you can get cheap and strip it and put higher market parts on it. Some Walmart aluminum frames are basically race crimes. But it cost money to make it a great bike that's why I just go to bike shop to buy price is about the same. My opinion. Love ya keV cenrtal

Everyone has their thing or comfort zone, mine is the Suntour NCX SP12 SUS seat post on my Surface604 SHRED ebike.

I would always have a dropper for hardtail or full susser (I have both). I live in mountainous country though. I imagine if it's flat, it wouldn't matter as much. I'd still want a dropper though. Even on my hardtail that is set up for urban use - using the dropper while braking hard is phenomenal.

I use a Cirrus Body Float suspension seatpost and Cloud 9 suspension saddle on an electric fatbike so I can ride fire roads.

Hi: Enjoy your videos. I’m waiting for my Zoom suspension post for my New Magicycle Cruiser. Thanks

I used to ride BMX in my teens and early 20s 2ith that old plastic seat lol. But 20 years later I definitely want a suspension seat post for my moutain bike. The old glutes cant take the abuse any more lmao.

you sound like me. when I am done with a bike is the frame alone from the original LOL> that is the fun of it.

Those zoom suspension seat posts are junk, had one for the last year and it barely made a difference. Decided to get the suntour sp12 ncx and its like a night and day difference.

You'll see this on my xtrada 5 when i go to chickasaw trace. Oh wait i still trying to pick if im gonna use this or the tranz x jumpseat dropper post when i go there.

Thank you!!!;)

I use a PNW Coast dropper post with 40mm of suspension on my Hardtail trail bike and Gravel Hardtail and it is so nice. I steered away from suspension seatposts cause when I was super heavy it couldn’t support my weight but with the air sprung suspension it’s stiff when I need and compliant when it gets rough. Plus I still get a dropper 😬

With things as they are, I'm (6'1", 230) interested in a large vs. medium size frame full suspension bike that might be available for order from a big box store. Have the optional idea of being able to convert to a mid-drive electric with some other mainly comfort mods. Want to try to minimize jolting, jarring, bumpy rides.

It is dual suspension in theorie, but it doesn’t makes it a full suspension bike. Full suspension Bikes still have much more grip then just a damping seatpost

My 1998 mongoose a50r has a factory suspension seat post. Its kind of weird for a mountain bike but ok i guess

I used a suspension seatpost from Rokshox on my hardtail back in the late nineties or early two thousands. I can’t remember.

I been trying to get that MT for like 5 months, OUT STOCK EVERYWHERE 😩 😫

I love your content, but not the moments that you have a cam filming seat post motion. NOT a KevPosterior fan. 😉 I'm not worried about your creative parts selection.

With mountain bikes it's the perfect platform to mix and match a lot of odd colors to make the bike match you and usually I really like that about bikes. I get how if the same thing was applied to something else, say like a car or a house then it probably wouldn't work out as well or wouldn't look as good. But that's just how I see it.

Suspension seat posts are bad for your knees. They are constantly changing both the distance between the seat and the pedals and the angle between the seat and the pedals. When the seat is too high, it can screw up your hips and when it is too low it is very bad on the knees.

Still have one of these from the 90s rockshox makes one of these I put on my specialized chisel hardtail for a gravel event

I tried a nobrand fairly cheap (probably Chinese) telescopic seat post - rubbish! BEING telescopic it would "BIND" - INNER tube would stick to the manifold on the outer tube - due to nonlinear forces - I tried experimenting with minimal and maximum preloaded spring and everything in between! Still the "suspension saddle post" didn't suspend! I Will never again waste money on a telescopic suspension seat post! I WILL TRY LINKAGE SUSPENSION Seat posts - probably elastomer!

I wouldnt buy this for a mtb because most of the things that need suspension i.e jumps and rocks, require you to be out of your seat

Personally I'm getting one for my old Marin mtb I saw in came in 25.4 size good for old mtb.

suspension seat post is great on Lectric 2.0 on the road light offroad, but i don't care for it on a mountain bike trail. you need to stand to be safe not.

Can you remember the suspension stems from around 1992 ~ 1995ish

I ride dirt bikes & they have the clutch lever on the left & front brake on the right, our bikes over here also have the front brake on the right hand side, i find it strange that bikes in usa look like they have the front brake on the left hand side ?

I want suspension seat post on full suspension bike. TRI-SUSPENSION!

Front sus. fork, rear shock, dual suspension. Front sus. fork, rear shock, suspension seatpost, full suspension lol!

Tri suspension bikes. I’m calling it. That’ll be a commercial thing soon. Anything to be special, right?

Hi there, I’m new to the channel and I really enjoy watching your videos. I was just surfing through the Walmart webpage and found a bike you might be interested in review/possible project. The bike is the “Mongoose Bash”.

All the hardcore hardtail riders RN 🤮

Never seen one of these except a really old version from and OldShovel video. Interesting concept

Is there also handlebars suspension for bikes with no front suspension?

Not really a crazy concept- trek kinda does it on the procaliber with their isospeed decoupler.

Suspension seatpost? Is it a coil spring or compressed air ?

Who gives a poop what other people think. Ride what you like? I like it!

suspension posts are good for wasting energy while climbing and causing you to loop out.

Screw taboo, do what ya need to have fun!! I tried one, and will buy a few more!!!

No because your legs still take the brunt of the impact

There's an sr suntour one for around 100$, it's a linkage/spring suspension so it's supposed to keep the distance between the saddle and pedal consistent
