How to install a internally routed dropper post, Command Post.

[@djlarroc]

Best dropper install video on KZbin!

[@BikeTeacher]

Thanks so much!

[@s2perman]

Excellent- easy instructions and the reasoning behind slack cable and how to fix it. A good video is the camera and pretend that everyone is new to it. Never mind people rushing a step, thinking everyone knows. This was a good tutorial.

[@BrianRistola]

Thank you Bike Teacher - This video helped me get a TranzX post working again on a Kona Process 134DL.

[@BikeTeacher]

Awesome. Glad it helped. ⚙️

[@jimratzlaff3112]

Great video! I just bought a new dropper and having never installed one and unable to find much on the model I bought, I'm happy to have found this video. Thanks! Update: I installed my KS LEV SI dropper using your instructions. The only problem I had was with the measuring for the barrel. KS included a piece to measure the distance between the barrel and the housing, but there were no instructions, and I had it upside down which caused looseness in the cable. Once I figured out my error I was good to go. Thanks again!

[@BikeTeacher]

Awesome, good to hear.

[@gap9992]

Really good instructional video. Helped me a lot. Perfectly demonstrates why these days most droppers have the cable clamp at the lever end !

[@BikeTeacher]

Thank you. I really love those levers.

[@codrinn9999]

Thanks! Installing a new housing was the big issue for me, without specific tools. I hasld to improvise : I turned the bike upside down, fed the housing and the cable from the front hole to the bottom opening of the frame, there I attached the little metal cylinder that attaches to the seat post and I tied a shoelace to it. From there it was very easy to guide the unattached end of the sholace through the small hole and down the seat tube. Then just pull it and the housing follows the corect path. Then I followed this video. Hope this helps

[@BikeTeacher]

Great!

[@bikenbeers]

Thanks for the video instructions. Very clear and complete. I wish I had found this video in my earlier search as it could have saved me all the trouble I'm currently experiencing installing a seat post dropper.

Did you get to see the video I have on that? Let me go back and take a look.

[@BikeTeacher]

Glad you got it. I for got my bike came with housing pre-installed. I have been experimenting with with cables to help find the routing. I clipped the end of the derailleur cable head and run it through using a magenta or pick to help it through. Then slide the housing over it.

[@MikeAndrzejewski]

The measurements you gave were super helpfull! I had a few issues trying to get the cable sized!

[@MikeAndrzejewski]

As a side note, you only need the second hex wrench to make it really tight..

[@geedoctor]

Thank you for the video. I like how it's real world - you encounter a problem, like all of us, and trouble shoot it - like with the electrical tape. BTW, a cheap pair of hemostats or a needle driver would probably make your life a lot easier on the nut installation part.

[@BikeTeacher]

Thank you for the tips. I will keep that in mind when making videos, to allow for problems.

[@alwaysbelievechrist4688]

the Kona remote 160 came with this seat post, I think carbon fibre is better but this is kinda cool!!

[@BikeTeacher]

Ya. I think so.

[@NonLegitNation2]

watching this to prepare for when my dropper gets delivered next week. You know the install would be a ton easier if these companies just had a farrel (don't know if that's spelled right) on the lever end. Then you could just install the cable with housing, install the dropper post and push it down, then pull the cable/housing to whatever length you want it, cut the housing and install the cable into the lever.

[@onlyonecannoli3952]

Any monkey can put a cable through an already installed housing. What we wanted to see is how you routed the plastic cable housing through the frame.

[@BikeTeacher]

Now that I know your request, I can better help you. Thanks for your input OOC. That video was done a while ago I don’t remember if the plastic was in place already. I have some videos with an internal Ibis hookah frame. Or I can make a new one.

[@dean4072]

[@BikeTeacher]

Too bad you did not live closer, this could be a special project.

[@vanhelzer22]

You can use a 3rd hand tool up against the ferrules to eliminate ALL the slack before setting the cable stop

[@paulgiles7456]

Great video, really helped me fit my command post. 👍

[@BikeTeacher]

Awesome, glad to help.

[@givreycham]

Really useful video...I am going to fit mine tomorrow.... Just wondering if a bit of play in the cable maybe a good thing in case you catch the lever accidentally ( like you mentioned with your knuckles ?)....but really helpful and you seem to have covered all the things that may become a "challenge'!

[@BikeTeacher]

Thanks! A little play may or may not be a good thing. The lever could be touchy and not respond therefore not activating the post.

[@ScorchinScooter]

Great video! Thanks for the tips! I plan on installing a dropper post on my 2017 Giant Trance 4. I am sure the concept is very similar. Too bad it is almost Winter here so I will probably do it next Spring! lol.

[@BikeTeacher]

Sounds good. Glad you liked it.

[@mcscabby]

Nice video. Thanks for posting. Unfortunately the Command Post is not very good. I’m taking mine off my 2017 Specialized Enduro. It rattles (from day 1), loses pressure, and does not operate smoothly despite being rebuilt by the Specialized dealer. I am replacing it with the same X-Fusion unit that came standard on my Specialized Epic, which works way better. It is nicely dampened so it rises at the perfect rate and is very well priced. Specialized obviously thought the Command Post wasn’t great when they switched to the X-Fusion.

[@BikeTeacher]

I can say the same thing now. Mine was loosing air too. I am happy with my LEV, very smooth and reliable. All the ones I run into are still running smooth.

[@tomg5661]

Nice video. I want to replace a Xfusion Manic 150 mm dropper tube with a 125 mm unit in my Turbo Levo MTB. Can I use the same cable or do I need to have a longer one to reach the shorter 125 mm unit? Thanks, Tom

[@DavidDartsch]

Thanks for the video. The finicky 17mm cable trim reveals what a bad design this dropper is. The reverse design where the cable exits through the lever is so much easier since you can get it working well before cutting the cable. It’s way easier to install.

[@BikeTeacher]

I agree. It’s so much easier to dial in the housing length and trimming.

[@quesnoy1]

I didn't catch it but did the internal cable already have a barrel attached at one end? Or, did you have to attach a barrel at the lever end as well?

[@billpottinger1136]

Perfect pace, xlnt video, well done!

[@BikeTeacher]

Thank you!

[@bensabs5732]

Hi, me i know what housing cable cutter did you used?? Brand and model??thanks..

[@MichaelMurphyD]

Great video! Stumpjumper 2019 Evo, and my drop post broke at the cable connection 😔😔

[@BikeTeacher]

Oh no!

[@juluisreyes9094]

I believe the dropper have a plastic end bottom cap that also serve as a guide to measure that location of the small metal cylinder on the wire cable.

[@BikeTeacher]

Yes, some will include it for initial set up. I like the levers that allow you to pinch the cable at the lever and not the dropper.

[@waynethansen]

Fantastic video. Thank you so much!

[@BikeTeacher]

Thanks, your welcome.

[@hollisbabybeats]

I don’t understand how after cutting the housing an inch above the seat post how you easily get another 8” of housing past the seat collar again. I have to slide my lever over to get close to having that much slack. Also before cutting your housing that 7” you had that nut thing on the end of the cable, why?

[@rickbelieves7652]

Do those Dropper Posts ever hit you on the way back up if you aren't positioned properly ? Ouch ?

[@tonigamer1742]

how to do it if the whole cable is pushed into the tube inside how do I take it out and put the dropper post back? the barrel is already on it

[@GH-bg5jw]

An old spoke ground to a point also works well for a pick

[@BikeTeacher]

Yes, and inexpensive.

[@jaredguthrie6593]

Not sure if you're still checking comments. But any suggestions on where I can find a silver barrel like this? I've checked a few local bike shops and no one has one. Thanks in advance

[@BikeTeacher]

Not sure, I would check with bikes shops, they mY have extra laying Around. The manufacturer mY give you one.

[@bikewhorder]

My carbon Ibis frame has cable stops in the bolt on plastic inserts, Does this post only work with a continuous cable? Do I need to drill out my plastic stops?

[@bluesaddict101]

[@BikeTeacher]

Glad it was helpful!

[@annaabramov1201]

Great explanation!

[@munkley123]

Thanks for this. The cabling broke on my levo and I tried to do it myself and ended up with massive extra cable. This allowed me to get the correct size without guessing

[@BikeTeacher]

Great! Glad to help out.

[@wouterdevos1091]

Thank you for this very clear video. I have a question though. The lever that you pull with the screwdriver, the one where you need to fit the barrel in, is completely stuck in my dropper post. That's why I snapped my cable.

[@BikeTeacher]

It's jammed? It may need a complete disassembly to see what went wrong. Something bent or jammed. It also may not be repairable. May need new internals.

[@hafizmistam554]

Great video. Thank you very much.

[@BikeTeacher]

You are welcome!

[@joeytoribio2035]

In hindsight he didn't need to give the cable that extra 2mm for the silver barrel if you have to eat up that much play adjusting the seating slack at the end anyway.

[@tomekm6887]

Great video, super helpful!

[@BikeTeacher]

Thanks Tomek

[@Lilljoescratch]

Thanks for tips on #9 barrel is a pain I put chain lube in my sheathing 😉

[@pault477]

So I have one of these and need to travel by air. The case I have requires removal of the seat and post. Is this pretty easy to remove and reinstall ? I have a Diverge expert Evo gravel with a X-Fusion Manic Dropper, 50mm travel

[@BikeTeacher]

I do not know that one specifically but they all should disconnect at the seat post with a quick release style or maybe you can slide the housing in to the frame to remove the post just enough off the bike. Removing the lever from the bar nay help.

[@islandaerial3414]

I had a Stumpjumper in the 80s ffs LOL Somewhat useful. My Cube is pre-housed. Cheers

[@williamlehecka6697]

So a bit of confusion. After I cut the excess cable housing after measuring the extra from my seat post the cable housing was now much further down into the frame. I did not have the extra cable housing that reaches outside the frame so I can put the ferrel cap on correctly. What did I miss? Did you allow much extra cable housing in the front of the bike at the beginning when you cut one inch above the seat post?

[@jacksonkrause8816]

What happens when you want to make the seat taller? Do you have to redo everything?

[@BikeTeacher]

You should have enough housing, always try to leave enough when first measuring. Thanks

[@fortnite_gameplay7276]

Do all measurements work for all compatible dropper posts with bike??

[@BikeTeacher]

Yes it should be the same.

[@mtbmt6908]

What do you do if you have a 2x10 thus having a shifting lever already on the left taking up the levers space. Is there room for a remote? Or would I have to convert to a 1x. I ride a Trek Fuel ex 5. Thanks.

[@BikeTeacher]

Yes there is room for a remote. A particular grip allows you attach it to the end of the grip nearest your shifter. Like it’s integrated. It would take the place of the grip clamp.

[@mtbmt6908]

@@BikeTeacher Thanks!

[@bruntley1]

Where can I get that barrel that goes on the end that attaches to the post or do u know if theres a cable I can buy that has barrel on both ends of the cable?

[@BikeTeacher]

Places like Jensen, have small dropper post hardware parts. Here is a link.www.jensonusa.com/KS-Cable-Clamp-Cable-Clamp-Lev-Lev-Dx-Lev-272?loc=usa&gclid=Cj0KCQjwlPWgBhDHARIsAH2xdNebofi4lYg04LwCivJkPQdyTBUdZRnq5DqLB-09-FKeAfv-Pv_7WvkaApj5EALw_wcB

[@user-yv2cz8oj1k]

That's helpful... I think I'll buy one with an external cable. :D

[@BikeTeacher]

Yes, less fuss with internal routing in some cases but sometimes the externalhousing may move around too much and or rub and get caught on parts of the frame. For the most part you can lightly zip tie it.

[@JamesTierney90]

[@BikeTeacher]

Hey, thanks!

[@davecooke914]

Enjoyed video what's easiest way get cable though frame

[@BikeTeacher]

Easiest is to make a sheath (liner from a housing and install it onto the existing cable before removal. if its too late for that, fish the cable in and use a thin telescoping magnet to grab the cable end. You could put a bend or curl at the end of the cable to help guide it on turns.

[@blacktiger955i]

Good instruction video but I can't help thinking that your brakes levers are on the wrong sides. Motorcycles have the front brake on the right hand and so does my Turbo Levo FSR as supplied.

[@BikeTeacher]

I found that it is common for bikes to have the front brake lever on the right side if they are electric or from the U.K. I don’t ride motorcycles so it would be a learning curve for me.

[@davidmarquez2555]

did I miss when you routed the housing?, that's what I wanted to see.

[@BikeTeacher]

Here is a video with some internal routing tips. kzbin.info/www/bejne/pqa0faBun9yDe8k

[@jievyjumawan5163]

You think I will be able to do internal routing with my 2020 Rockhopper 27.5?

[@BikeTeacher]

As long as there is a opening connecting the down and seat tube you should be okay. I assume there is a routing hole near the headtube?

[@jievyjumawan5163]

Bike Teacher yeah I see it now. I still haven’t received my bike, I just ordered it.

[@garrettevans8795]

[@usmanmohammed4043]

Hi I just wanted to ask that when I installed my dropper, I only tightened one side of the barrel - meaning that I didn’t hold the 3mm side whilst doing it. Will the barrel come loose and is that something to worry about?

[@BikeTeacher]

Possibly, it may not have allows you to get proper torque. Even thought the amount of force it’s needs is not much. It’s a 50/50 chance. Thanks

A bike shop may have one laying around or online stores. Look for barrel adjuster for brake or derailleur. Which ever you need.

[@CM-1723]

The brake cable end barrel what he uses , what's the actual name of them I can't find them anywhere

[@BikeTeacher]

Ferrule cap, housing end cap

[@CM-1723]

@@BikeTeacher thanks mate , I found one yesterday . In the UK they seem to be called solderless barrels . The ones with the screw in to clamp on the cable that is . The way it's done now is you buy a regular MTB brake cable and put the barrel end in the dropper post thread it through , then at the thumb lever there's a screw where the cable gets clamped down onto the lever without the need for another barrel end .

[@markrichard862]

How would you do the cable if my internal downtube hole is on the same side as my lever has to go on.

[@BikeTeacher]

That’s okay. You can still run it on the same side. They do it for derailleurs as well. There should not be added friction.

[@PopovskiDarko]

Question on mine Specialized Command Post Internal routing : When I ride it sinks down after a few seconds , and I have to bring it up with the lever , and again after a few seconds, something gets loose or I don’t know what it is , the pressure is right , please help , thanks

[@BikeTeacher]

Possibly too much tension on the cable. Use the barrel adjuster to loosen the cable, screw the barrel clockwise to collapse the barrel adjuster. If you have no more room to turn it clockwise you will need to loosen the cable at the pinch bolt and reset the barrel adjuster to half way at least.

[@BikeTeacher]

You can do a test and release the cable (barrel) at the seat post. It should be a quick release, Test ride it and see if the seat drops by it’s self. If it still falls by it’s self you have an issue inside. I would talk to Specialized to see if it can be fixed by you are it may need to be sent in.

[@PopovskiDarko]

Thank you very much for the quick response , I will try to fix it this weekend and see if that worked, will let you know

[@willesloco]

How did you get on? I have the same issue with a new bike. The seat drops while I'm riding. I've checked the cable and it seems to be setup properly. Tension is good. I'm thinking this could be a fault with the seat. Have to wait till Monday to phone the supplier!

[@willesloco]

I fixed it! the mechanic that set the bike up cut the cable to less than 12mm at the seat post :( I managed to eak out an extra 2 mm to the bitter end. It's not perfect and I will have to replace the cable, but for now it works. Millimetre's make all the difference with this seat post setup for the cable tension. It clearly states 17 mm in the manual so I do not know why they cut it to 10 mm?! Thanks for the video Bike Teacher, it was very helpful indeed.

[@ollieljk]

great video, thanks!

[@BikeTeacher]

Glad you liked it!

[@user-cl5bv9mv9w]

Are the cables universal for all bikes or do you need a specific one per bike model?

[@BikeTeacher]

All droppers use the standard derailleur cable. There is a longer cable reserved for tandem bikes.

[@richardb7093]

Why not eliminate the possibility of an error and do all the trimming at the level?

[@psimetric8887]

Install the dropper is very easy, install the cable into the frame is the most difficult

[@BikeTeacher]

Ya, this style is a pain. I like when the cable head mounts to the dropper, then trim the cable at the lever.

[@brianh8485]

How did you route the cable itself? I'm installing on a trek. Did you have to uninstall the bottom bracket or is this not a fully internal cable routing?

[@BikeTeacher]

It is fully internal. This carbon stump jumper has its own routing tunnels. I believe I had to guide it the rest of the way into the seat tube.

[@alwaysbelievechrist4688]

i would have tightened the cable from the handle bar because if incase the set screws come a little loose, you have take the whole post out just to tighten it plus it makes it a lot easier assembling and cutting your 7 inches from handle bar height and tweaking from there.....my 2 cents!!

[@BikeTeacher]

I agree. 😁

[@flowstateofmind]

Is it supposed to jump out like that? You would need a toque to ride that bike safely.

[@BikeTeacher]

I never liked the Specialized dropper posts. You always had to over pressurize them to function properly.

[@elkat_bori_pr7791]

Transmision or brake cable?

[@BikeTeacher]

Dropper cables are typically derailleur cables.

I would start from the top of the bike. I feel gravity helps when trying to guide the housing (pipe, tube) through the frame. Maybe start eh the process with a cable. get the cable installed first then you can slide the housing over it, then you can pull out the cable.

[@stewiegriffin8105]

Camilo Lopez Your bike seems to have all the shifter and brake cables externally routed. But give a check near the seat tube (near the bottom bracket) for any holes for a internal routing to the external cables. If you don’t find them I think you got to get the Brand-X ascend 2 externally routed dropper.

[@BikeTeacher]

Hi, sorry for the late response. I always look at the frame for holes for housing routing like you mentioned in your other comment. Some frames run tight inside especially those that force the housing around or under the bottom bracket. This does not allow for free space for the excess housing to go.
