Eightpins NGS1 Integrated Dropper Post - Review

Eightpins dropper seatpost


Eightpins is both the name of this elegant dropper seatpost, and a reference to its eight-pawl mechanical latching system. For those not yet up to speed on the Eightpins concept, it is a mechanically actuated system, designed from the start to be integrated into the seat tube and thus requires a dedicated frame. A seal-head replaces the typical seatpost clamp, and there is an internal sleeve inside the frame which houses the bushings that the post slides on. The aluminum post is 33-millimeters in diameter, so it is stiffer and stronger than a conventional dropper and thus, can safely extend farther out of the frame. The remote is cable actuated and the system is powered by a simple

air-spring strut, fixed by a though-bolt near the bottom of the seat tube. Eightpins' integrated dropper is lightweight (50 grams lighter than a RockShox Reverb at 170mm travel), robustly made, and it makes a good case for bike makers to adopt the concept as the next logical step for dropper posts.

The gas-spring and latching mechanism are attached to the frame with a through-bolt.

Depending upon the size of your bike, you can enjoy up to 220 millimeters of drop that can be customized. Eightpins droppers are purposely shipped longer than most riders will ever use because they are designed to be easily be cut to length and independently adjusted for saddle height and stroke length. Riders can choose to maximize their drop for a given inseam and frame size, or to limit the post's upper and lower range of movement to suit their terrain or riding styles. Technical advantages compared with conventional droppers include longer strokes, lower weight, and a simple, user-serviceable mechanism.

How It Works

Eightpins is a simple and robust design, largely because its mechanism doesn't need to be squeezed into a 30.6-millimeter tube. The first 100 to 140 millimeters of the frame's seat tube needs to be reamed to accept an insert which houses the post's sliding bushings. The insert is fixed in place by the external seal head. A slender gas strut that is mounted to a through-bolt near the base of the seat tube extends the post. The "Eightpins" latch is mounted to the large, fixed-end of the gas strut.

Latch number one: The Eightpins latch has a pair of keys that slide in tracks machined into the inside of the sliding stanchion tube (just like most droppers do, to keep the saddle aligned). Opposite the keys, however, are a pair of expandable pawls that latch into a ladder of indexing grooves which run the entire length of the inside of the stanchion tube. Each of the pawls have four indexing teeth, hence the name, "Eightpins."

The cable-actuated remote lever retracts the pawls to allow the post to drop or extend and when released, the pawls lock into the indexing ladders. It's a simple and reliable mechanism that offers positive stops, spaced six millimeters apart. It feels very much like an infinitely adjustable post, but the engagement latches with a positive sounding "click."

...Depress the remote lever to adjust or to remove the stanchion tube. The latch is fixed to the top of the air-spring strut.

Latch number two: Unlike a conventional seatpost, the Eightpins dropper has no external clamp with which to adjust saddle height at full extension. Eightpins handily solved that issue with a second latch that sits on the end of gas strut's shaft. The second latch also locks into the stanchion's indexing ladder. Turning a dial that is nestled into the seat-clamp head unlocks the latch, after which, the user need only to depress the remote lever and the post can be re-positioned up or down to set the saddle height at full extension (or removed completely from the frame). This adjustment only requires a 2.5mm Allen key, used as a lever to poke into a hole in the dial and rotate it. Saddle height can be changed anytime, anywhere.

Cut-to-Fit Post: Syntace and Liteville were the first-adopters of the Eightpins dropper, so it was fitting that they teamed up to assemble a review bike armed with the system. Liteville sent a medium-size 301 all-mountain bike and, to give me the full experience, they left the Eightpins post uncut at the full 190-millimeters of travel. To get the lowest drop, while maintaining the proper topped-out saddle height, I had to cut the stanchion tube with a hacksaw. The good news was that there is no mechanism inside the stanchion tube, so the operation is about the same as trimming a handlebar or fork's steerer tube. Eightpins furnishes a handy guide that shows how much you can trim, and if you adhere to that, the job takes about fifteen minutes, with most of that time spent washing the shavings from the stanchion tube.

Eightpins dropper seatpost
A look down the segment I cut from the stanchion tube shows the seat alignment tracks on either side of the indexing ladders that engage the Eightpins pawls.

I ended up cutting about 80 millimeters from the post, which left me with 152 millimeters of drop. I could have upped that to 160, but I wanted to leave some extra post extension for another test rider whose saddle height is slightly taller than mine. You can deviate from the charts to further maximize your dropper's stroke, but you'll need to follow more detailed instructions, which may include adding bottom-out spacers. The key is to shorten the post as little as practical, without causing the stanchion to bang into the through-bolt when you completely retract it. On the flip side, you also need to ensure that the stanchion overlaps both insert bushings at full extension so the post is safely supported. It's common sense, but some cyclists lack those genes.

Travel options and weights are starting points.

Smooth Push remote lever: I am usually not a fan of radial type remote levers, but Eightpins' version has a very ergonomic shape, with an outward flare that emulates the action of a paddle to some extent, but without taking up as much space. It's called "Smooth Push," and the CNC-machined and anodized remote is furnished with a length of aluminum tubing with an adjustment barrel at one end that can be custom bent by hand to direct the cable housing exactly where it best fits your handlebar arrangement.

Eightpins' radial remote lever actually feels ergonomically correct. It's designed to keep your hand in a more natural position on the grip.

Saddle-impact clutch: The innovations keep coming. Eightpins anticipated that the post or saddle could sustain damage in the event of a crash, so they designed in a simple clutch at the base of the gas spring that will break free and allow the saddle and post to rotate up to 45 degrees right or left upon impact. The rider can then return the saddle to normal with a strong twist. The clutch tension is adjustable.

Offset bushes and saddle clamps: Not all seat tubes will accommodate the unobstructed length that the Eightpins assembly requires, so its designers include offset bushings with the kit that allow the post to accept a small amount of fore/aft misalignment. Saddle clamp-heads are offered with minimal offset (like the RockShox Reverb) and also with a 25-millimeter rearward offset that is intended to let

frame designers move the seat tube forward to clear the rear tire at full suspension compression without resorting to the bent tube that is commonly used to solve that issue. The Liteville 301 is designed to take advantage of that feature.

Ride Report

For all the tech it embraces, the Eightpins dropper post is remarkably simple to use. Once I was accustomed to the click sound that the latch makes when it locks in, I rarely thought about it. It takes little effort to depress, and it returns with crisp authority. To establish a mid-drop saddle height for rolling trails, simply keep the lever depressed and let the post follow your movements until your bum is at the chosen height and "click" you're there. When I returned to bikes with conventional hydraulically actuated posts, I found myself occasionally checking to see if they were broken or needed adjustment.

I like how the Eightpin post gives the bike a retro look. The post's unbroken 33-millimeter shaft rekindles the cleaner lines of the pre-dropper era. The remote lever is also a low-profile design, and it has a similar effect on the look of the handlebar. That big stanchion tube feels stiffer than a Reverb or a Transfer at similar extensions and, aesthetically, I like it much more than the slender column of a clamp-on post. To be truthful, I would be perfectly happy to rock my Fox Transfer dropper for the rest of my life, but I wouldn't shed a tear if bike makers adopted integrated droppers, especially if they performed as effortlessly as the EightPins does. It's next level.

Reliability has been a non-issue with the post, which has been racking up miles, mostly in dusty conditions. I've crashed it a number of times and knocked the saddle out of whack, so I got to use the clutch feature. I'm not so sure how beneficial the clutch is for the rider, but if it protects the post, that's okay with me. It takes a fair amount of strength to move. The saddle never went askew from leg pressure while I was riding, which was an initial concern. So far, there is a small amount of fore-aft play in the post at full extension (which has been there from the start) and no rotational play at the saddle at all. It sounds and feels as good as new. I've had it apart for a look at the internals. The wiper seal has done its job, and there are no metal bits floating around the pawls or inside the stanchion tube. Evidently, the folks at Eightpins did their homework.

What If?

What if you have to sell your Eightpins equipped bike and the stanchion is cut too short for your potential buyer? Eightpins sells the full-length replacement stanchion tube for €150. What if you get a major sponsorship from a parts maker who wants you to run their conventional dropper? Well, in the case of Liteville, you can purchase a clamp-type seat collar that fits into the same location as the Eightpins' bushing insert and seal-head. The clamp conversion is also insurance for frame owners with worries about being left behind in the race for new technology. For now, Eightpins is well ahead of the curve, and they've designed the post to be easily serviced by its owner. Its parts are simple, and it should be a lifetime investment.


Pinkbike's Take:

bigquotesI'm a fan. I like the Eightpins' ease of operation compared to the two most popular conventional hydraulic droppers. I like the fact that it isn't full of oil, and I like their integrated concept. Not surprisingly, its been slow going for Eightpins to break into the OEM market. Presently, Liteville is their major partner, but there is an up-welling of smaller builders, eager to set new trends, who are beginning to displace larger, more established names in the high-end arena. This season may be the turning point for well-vetted innovations like Eightpins' integrated dropper to gain wider acceptance. I certainly hope so.RC

 @Axxe: Can you name one society that has prospered by putting people first as opposed to business (for a sustained period - like, decades) or vice versa, business before people? That's a point as well as a question. I don't think you'll find one. It's always about the balance, and always has been. While the money returning to the US is a good thing - just like FOX News told you - what Tucker didn't tell you is what that money was doing to benefit you (and by extension the US) by being overseas OR how that money being back in the US might hurt you. Almost 95% of the money that will be returning (most of it wont anyway) will be reinvested in the money markets. Less than 10% of surveyed business has said that money will be used to open any manufacturing here. And whats worse about the whole returning money idea you've hung your hat on is that the new tax bill makes it easier for corporations to do hinky stuff with that money, stuff like what caused the 2008 crash. So, I just want to wrap it all up here; FOX News told you "muh munny is cummin' back and that's goooooood" and you have no idea, intellectually speaking, if that's good or bad, so, FOX News tells you "brown people suck, even the +700,000 who have lived here most of their lives and have had extensive background checks (and passed!) and contribute to all our nice lives by having jobs and obeying laws", are you a racist because FOX News told you to or does it come naturally?

 As someone who makes money fixing dropper posts, I'm disappointed to see that line of revenue threatened by this system Smile

In all seriousness I think this is a simply fantastic idea. Here's why: the two most common (by far) dropper posts we see here are KS Levs and Reverbs. Both of them are somewhat failure prone, usually due to one of three things happening:
1. Sealhead comes loose and dumps the oil out of the post. This is due to the immense leverage on a small diameter tube, with narrowly-spaced bushings taking a huge load and levering on the sealhead (particularly on the Reverb, but tube flex has a similar impact on the KS) which makes it come loose even when properly torqued. The longer the drop, the more leverage, the more failures we see.
2. Air getting from the air chamber into the oil and causing it to develop sag. The Reverbs are particularly bad for this but it eventually happens to the KS as well. Our belief, though this is very hard to test and prove, is that this is due in no small part due to flex of the upper tube causing poor sealing between the IFP and the inner/outer tubes.
3. Valve actuation problems on the KS (seals sticking) or remote leaks/thermal shrink on the Reverb

Other mechanical (or semi-mechanical) posts (DOSS, X-Fusion Hilo etc) more commonly suffer leakage with the pressurised sealhead having to seal against the outer tube - that seal has to deal with all the flex of the post, and in general is more leakage-prone.

All of these are most likely solved with this design, since you have a larger, stiffer post with less flex and bushing load issues, no hydraulic chamber at all (and what looks like quite a well-considered incremental adjust system), and a mechanical remote and entirely mechanical internals. You also get lighter weight, longer drop and far less of a constraint on the size/strength/stiffness of the internals. Not to say it's guaranteed to be free of problems, it may well have its own, but that's a lot of steps in the right direction to say the least. Well, except that we probably won't make much if any money out of servicing seatposts if this becomes more widely adopted...

I can guarantee you that the people designing dropper posts all over the world are doing their best to make the posts the absolute best that they can make them within the constraints of reality (eg a 2kg post that costs $4000 is not likely to sell no matter how good it is), and for all the quibbles with them (including my own), the Reverb was the product that literally changed the entire MTB industry by bringing Gravity Dropper's concept to the mass market in a sleeker and more user-friendly package. But progress is inevitable, and if it ever reaches the point where bikes are as good as it is physically and practically possible to make them, sure, we might need to find some other line of work, but that point is realistically not imminent.

I should also point out that the original comment was definitely not meant to paint those posts in a poor light - I run both of them myself.

 Liteville is quite popular here in Europe (most people I know prefer this over "carbon") though I doubt this goes for North America too, so you're safe for the time being. It always struck me how the industry got a bit stuck with those seatpost interfaces. Originally the seattube was designed to fit a rigid seatpost. Then they came with dropper type seatposts that could be retrofitted to these standard seattubes. The only advancement in frame design we've seen since is that the geometry is no longer based around seatposts with setback and they have "stealth routing" (which limits how far the post can drop inside the frame). They (frame and seatpost designers) never got together to design the system as a whole. Until Liteville and Syntace did.

 Get this: I had the Fox Transfer and was "liking" it. The post had maybe 1mm of twist movement which is inline with specification. However, when the weather got cold, I was not liking the Fox Transfer post.

So I sold it to my friend and it made him extremely happy, but I needed another dropper and was not interested in a air/oil dropper. So I went with the E13 TRS+ dropper because of the price compared to the " Bike Yoke - Revive". Notably, the TRS+ has more post twisting than any other mechanical post, and this is due to the keyway design. --TO which, I had some delrin keys made up for the keyway and it has removed about 50% of the twisting.-- I contacted E13 with my mod, but have had no reply-- I'm pretty happy with the action and durability of the TRS+ dropper, as well as the allowance of maintenance by the consumer without voiding the warranty. I just wish E13 would show me some prototyping with delrin keyway keys to remidy/lessen the twisting. If they make the keyways keys out of brass as wide as the delrin keys can be, the brass will mill out the dynamic side keyways or the keys themselves, creating more twisting. The delrin keys will not mill out the slides on the aluminum sliding post, the delrin does not mill itself unless there are barbs in the way, has the ability to crush and rebound, and, is self lubricating.

I'm currently looking for a contractor to make a bunch for me to get out to people, but I also need E13 to be on the up-and-up with my progress.

Thing is, I'm like BASF. I look to make things better, faster, stronger; because Tim Allen was a role model!

This year, around summer, I do plan on getting the Revive Dropper, but am hoping that some manufacture designs a consumer HT and FS frames with modern geo that accommodates the 33mm post with anchor holes near the BB. And, if a person does not want to use the 8-Pins anchored dropper, they can put rubber plugs in the anchor welds.

 @millsr4: I think there is a lot to be said for the specialized wu design. My post is a fox 150 drop, and I still find my thighs squeezing the seat when I don't want them to. I think a 150 drop, 30 degree rearward rotation would be a great solution. Bigger drops are definitely required because of the saddle angle we need for climbing.
  • + 9
 This would be seriously easy to introduce as a frame standard without actually having to be used by the dropper until the consumer chooses to buy it. Then the introduction of a new seatpost size that would be stiffer than current 30.9 and 31.6 diameters to be used if an eightpins post is not desired.

 You've got to be kidding. How long have the enthusiasts rebelled against pressfit before it started to be removed from new designs? No manufacturer is going to want to add more complexity and cost for 'what if' for fringey dorks.
  • + 3
 @scottzig - I think the anger towards pressfit is that 1) if often sucks and 2) you can't put a threaded BB in there.

What XCMark is suggesting (I think) is that frame builders use a larger diameter seat tube that would accommodate this post, which would also make it easier for other dropper manufacturers to make a better post with the additional room. I'll add that it seems like it would be simple enough to include an insert (like Liteville does in this case) that would allow you to still run an older, narrower post if that's your preference.

 Moving the seat tube forward like that and then just using an offset seatpost to get it to the right place seems like a better solution than the extreme actual seat tube angles some bikes use, which can put the seat in a weird place for tall riders. Also maybe a good solution for bikes with rocker links instead of bent seat tubes to get the pivot where it's needed, since the bent seat tubes often limit dropper insertion as well.

 So, what if you have Starling make Swoop for you and ask for it to make it eightpins compatible? Should probably work out fine. For a short while I thought of having this done for my BTR but decided not to. First of all I don't use a dropper because I simply just leave my saddle low most of the time. Secondly it would probably require a fair bit of development from them as they're pretty anal about not getting water inside the frame. Internal cable routing is possible but it takes some considerable effort and dedicated tools to do it to their standards. Not saying Starling has a lower standard but he might have a different view on getting water inside the frame. That said, I haven't actually asked BTR about it as I didn't need a dropper in the first place. But a custom frame builder or at least a frame builder that does custom options might be able to do it for you. Maybe even Nicolai and Orange would do it.
  • + 1
 @speed10:I did not search the interweb for anything before posting, so I didn't know about Syntace building bikes or not (DMR alike) and the text was not very clear about it so hence my interrogation.
I was not bashing the product, more questioning if it's pertinent to put to market something with that narrow possibility.
So it's down to 1 brand and custom built, and IMO looking at how the seat tube/suspension pivot are designed on "modern" mtb, they are not there yet.
  • + 1
 @inonyme:
The first year the 8pins is exlusive to liteville brands, to my knowledge it will be open standard from the second year onwards. You can basically use the "post pin" interface with a straight 34,9mm seat tube and internal routing and fit the post to any frame that uses this interface. The exclusivity in the first year is not a problem since they cant make these things fast enough anyway due to demand from the liteville owners alone.

please mind - at least one part of this post is hilariously expensive to make (the upper sliding tube is a masterpiece of cnc machining with the internal ribbing over 480mm of lenth) and therefore it will propably not be on reverb pricepoint anytime soon.

Since the post needs a straight uninterrupted seat tube it comes with the additional 26 or something set back so you can just move the whole seatpost forward. look at the litevilles seat tube offset on the downtube. Thats quite a lot.

Stefan (who actually rides the damn post and loves it).

 @RichardCunningham is there an easy way to remove the post for packing in a bike box for travel? I don't trust TSA to not accidentally extend it, not know how to get it back down, and then do something stupid if I leave it in the frame.
  • + 4
 Yes, you can remove the post in two ways. The easiest is to unlock the seat height adjustment dial (in the saddle clamp head), depress the remote lever and simply pull the seatpost out of the frame. The end of the air spring and the locking mech' will stick out a little, but you can use Gorilla tap to keep inside the seat tube while travelling.

The other way is to remove the through bolt at the bottom of the seat tube and then the whole assembly comes out the top of the seat tube. It's super easy to mess with. The cable hooks to the release mechanism half-way up the post, It's accessible and pops right on and off.

 if you build an integrated dropper that needs to use a propriotary mounting option why not go all the way?
its not like there is an option of just sticking it into any other frame if ony the tube would be thinner. and a bigger crossection will result in a stiffer tube. the current seattube diameters originate from when seatposts were non-droper, since then sizes have gone up to ccomodate the dropers, this is just the next step.
  • + 9
 Read the article again.

"The aluminum post is 33-millimeters in diameter, so it is stiffer and stronger than a conventional dropper and thus, can safely extend farther out of the frame."

That, plus it needs a dedicated frame to work anyway, so making it the same size as established standards is completely worthless.
  • + 14
 The established seat tube diameter standards weren't designed with dropper posts in mind though. Cramming all the droppery insides and sealing them properly in a space that small is hard. The standard seat tube diameter definitely needs to change to allow for lighter, more reliable and cheaper droppers. 35mm inside diameter is a good start. Also, you could easily use a shim to make it a 30.9 or 31.6, so there's pretty much no downside.
  • + 9
 I believe the stanchion is 33mm in diameter, but the frame uses as 34.9 seat tube, so still a standard size. Thats what all other liteville frames use. Syntace also sells some pretty nice seat post shims if you want to use a smaller size.
  • + 14
 You can drop in an adapter with a clamp and use any dropper you want. The 33mm tube lets you enjoy 220 mm of drop without having your ass waiving around like it's perched on top of a flexible flag pole.

 Its a 33mm tube sliding in a bushing on a 34,9mm seat tube. A diameter established for 11 years and used by liteville, scott, recently specialized (for the WU dropper) and others. Its not a novelty.

 Eightpins is a nice system, but it has major restriction - The seat tube should be straight from the top till the bottom bracket. Most frame manufacturers do not produce bikes with straight seat tubes. I do not know why, maybe they have their reasons ( not design only ). So I see more future in other reliable seatposts like 9point8 or BikeYoke Revive, which do not have this major restriction.
  • + 1
 I like this idea. not quite a big enough excuse to buy another 301 yet… but the next one… sure! the 301 already has the right size seat tube, needs to be shimmed down to most other droppers. Which also work, and are sometime also available in 34.9/35mm now. So you can still use a different dropped if the 8pins upsets you.

I can also verify that I still have nuts, even after riding a 301 for a few years now Smile I was kinda hoping to save on some doctors fees, all I got was a fun bike.

 @cherbein03 I find this amusing. Going from a 142 to mm wide hub to a 148mm wide hub is considered "change just for the sake of raping our wallets" .

 Totally agree that some things are forced on the consumer without much benefit. I would say if Trek, Giant, or specialized made this change on their bikes then it would be forced.

 More commercial science fiction from Pinkbike:

1. "The aluminum post is 33-millimeters in diameter, so it is stiffer and stronger than a conventional dropper": here we go again with the embarrassing use of the equation: bigger is stiffer and stronger. It is not necessarily true: measure please! Saying "it feels stiffer" is frankly completely ridiculous!!!!!!

2. Weight: we have no idea of the weight of the post. How much weight does the huge aluminum seat tube add to the frame?

3. What happens to all the carbon frames on the market? Do they have to integrate the aluminum seat tube into the carbon frame? Or do they build a carbon version, succeeding in what has never been done with a fork?

4. You are stuck with one post out of dozens on the market. Is that good? Is the post reliable? How does it compare with a Revive post? Of course we do not know because it has been used for how long? A week? Three rides?

And finally what happens if anything happens to the seat tube? You through away the whole frame?
  • + 0
 1. Yeah, the bushing is 10cm long and 33mm inner diameter. Its about the size of your fork bushings which have to take a lot more abuse.

2. Its lighter than a reverb, I own one, I had it on the scale.

3. No, they just need to have a 34,9mm seat tube and the post pin standard.

4. Its that good. Its that reliable. And yes, it will last.

5. If you dont like it, use any other dropper you want or no dropper. Standard 34,9mm seatpost and 38mm clamp will fit.

Finally: Why should it break the frame? The forces are the same as any other extended seat post.
  • + 1
 @Helmchentuned:

1. Again: larger diameter does not mean stiffer or stronger. Please come back with objective measurements and we can talk.
2. You (and pinkbike) are missing the point. You cannot just weight the drop post, you need to take into account the extra weight of the huge seat tube that you have to build in the frame. Look at the thing: it is absolutely massive.
3. You have not answered the question: how do you build this in carbon? and what cost? the only carbon legs in carbon on the market were from DT and they are no longer produced because of the stratospheric expense.
4. Point here is that as usual Pinkbike does not tell you how long, where and how it tested a product.
5. Frankly I see no point what ever to buy a frame with an integrated seat drop ... and then don't use it. Why? Just to carry the extra weight?

And finally: anything that happens to the seat tube (not the seat post) and you are toast. That is the reason why nobody integrates a rear shock in a frame.
  • + 1
 @duzzi:
1: yes it does, given the same cross section area a larger diameter tube will be stiffer to bending. That is objective basic structural knowlege of how tubing works. Also by increasing diameter while using the same manufacturing tolerances you will get less angualar play between sliding parts.
2. By using material more effectivly (by using a larger diameter) and also eliminating fluids and containment walls, of course this system is and can be made even lighter.
3.There are no difficult geometries in the frame interface surfaces. Carbon manufacturing is no problem.
4.Go read other reviews and opinions, I have yet to see negative experiences of eightpins.
5. Dropper seat post integration into frames of some sort is bound to happen as it makes good sense and current frame-dropper interface of a must have item cam be made a lot better. All moving wear and tare parts are replaceable so I cant see what issues there would be with frame ware. You break seattubes much?
  • + 2
 @duzzi:
1. Basically, it does. If its not an idiot building it.

2. Since this 301 aluminum frame puts some carbon frames to shame with its weight - I dont see the point of your argument.

3. I think the DT failed due to shoddy workmanship and crappy damping (inherited from pace), not because of carbon legs.

4. Well, I dont care how long they tested it. I OWN the product and I can tell you it outlasted any dropper post in my possession.

5. I still dont see where your extra weight idea comes from. The 301 Mk14 and the 601 Mk4 are the only frames that can currently be equipped with the 8 pins post. Both frames are LIGHTER than their non 8 post enabled predecessors. And on another note. Guess whats lighter. Moving the seattube forward or making it curved?

You are pulling your arguments out of your ass but tell me to be more scientific?

I finally got a seatpost that is lighter than the reverb, has more travel,is way more reliability and has the best sealing I have ever come across with dropper posts. You are bitching about stuff that is not true without ever having tested the 8 pins in the first place. Get a life.

What should "happen to the seattube"? I think you might crush it with an hammer, but other than that I dont think I ever had any problems with any of my litevills in the last... ...500 or so bikepark runs.

But on one point I have to agree: You dont integrate shocks into frames for about a million reasons, coulomb friction being one of them.

 The bike industry sells you a problem, then later sell you a solution! See the pattern?

 A great exploration into something that hasn't been explored yet - however, just because something hasnt been done yet doesnt mean that it really needs to be done. I'm no fan of dropper posts to begin with, but, if I buy a new frame it'd be nice to be able to move all my parts (aka dropper post) over to my new frame.

This is akin to making gear shifters or suspension integrated into the frame. Would anyone really want that?

 Saggy play-y heavy dropper posts with too little travel and questionable reliability? I don't think so

 @daweil: try a bike yoke

 @Dobba84: or a 9point8... the issues everyone complains about seem to be specific to the Reverb and any other mass produced, OEM spec'd dropper...

 @daweil: Yep, go Bike Yoke Revive: 120 to 185 mm, 465 to 580 grams, 360 to 390 Euro ... and absolute reliability.

 No. Just no. I see droppers like shocks and forks. I move mine from frame to frame. This is not for me.

 Article ended at "Cut-to-Fit Post."

 Why is that? Every dropper post article on Pinkbike has people bitching about 'too much' or 'not enough' travel. This solves both those problems perfectly.

 F*ck those cut to fit handlebars as well!

 liteville 301

 If this weighed like 200-300g then MAYBE it would be worthwhile, but it is actually heavier than most droppers, so what is the point other than a slightly cleaner aesthetic?

 Wait until it starts creaking like a mutha-@#$%er, then we'll see the praising...

 Other dopper post supplier communicate only the weight of the shortest versions. Sometimes also weight without remote. Then you also have to count the seatclamp. The specified weight from Eightpins includes all parts.

 Maybe the fact you dont need to service it every time you sit your arse on it like you do with reverbs

 @fussylou, @jcav5 - liteville got ahead of the game by never not having threaded BBs, just like SC Smile

 There are not too many frames that will be able to fit that post. Seems like a solution to a problem that doesn't exist.
