I love mechanics. Calvin, you remind me of my first mentor. I used to be a printing press operator. When you mix ink, you use a PMS ( pantone matching system ) book to identify the shade /colour you want. beside the colour are two formulae. One is in grams and one is in "parts" One day I was asking my mentor about mixing inks. He did not use a scale, just an ink knofe and his eyes. He was measuring in "parts" and I asked him.." how do you know that is two parts? " His reply was: " because I said it is " classic confidence. taught me a million lessons in two seconds !
I have a specialized epic ht, it has internal routing for the dropper cable and I've naively tried passing the housing cable by itself - no deal! Because of the pandemic bike shops were either asking 2 weeks to install my dropper post and up to US$ 50. I went and bought the internal routing kit from Park and was able to successfully route the cables and perform the installation. I had to be creative as I could not fit the magnet tip inside the frame, so I had to go the other way around and fish the cable, and it worked! This was my first act as a bike mechanic, so if I could do it with the proper tools you can too. Thanks park also for the great instructional videos!
Park Tool videos are the best without a doubt! The most thorough, easiest to understand, from beginner to the advanced. Plus I enjoy Calvins humor too, after all learning should be fun.
I love watching you make stuff look like a 'walk in the park' Calvin 👍- thanks - now I have what I need to fit my old bike with a cool dropper seat post, cheers 🍻🇬🇧
So helpful. Installed a similar dropper with exactly the same instructions for the first time and it went smoothly thanks to this video. Also, Park has excellent customer service -- had to purchase that handlebar holder.
Dropper posts come with plenty of disadvantages . The main ones that I see are the squish phenomenon , seal wear , play in the bushings and accessibility with some frame designs for cable line and actuator . Another one is removing the seatpost for cleaning .
@07:00 You have like no how tired I am after 1½ days of fiddling around my CF frame in order to get the wiring of a Shimano XTR Di2 into it without the necessary tools at hand to remove the bottom bracket for easier access to the internals. This felt worse than sleeving all the PSU wires of my main PC ( which, like this internal Di2 cabling, is something I'll never again be doing! )
A shopowner I sometimes purchase from stated that internal cable routing is neat but much harder to service , therefore he has to charge higher labour rates .
Like most bike stuff it's going to be expensive. It's definitely over priced but if you do a lot of cable routing it's necessary. With a little ingenuity one can probably make a cable routing kit themselves.
Can you please guide on routing the housing for dropper post on Giant Stance1 ?? have been able to pull a wire through but the housing gets stuck under the bottom bracket 😞
Its a tough pull on that bike. I recently pulled housing on one of those bikes and was able to pull from the front of the bike out the post. Not from the post to the front of the bike. Which way are you pulling?
So this may be a stupid question, but is it possible to pressurize a dropper post with a C02 cartridge? Is there enough pressure in the cartridge? Will the C02 damage anything? Thanks!
Chop saw? No no. Everybody with a few tools should own a good pair of cable cutters. I have Knipex 9561 190. These might cost more than other options (the Park ones look like they're top quality too.) I bought them for cutting cables but find I use them for lots of different things, Dyneema lines, piano wire, climbing rope. They make clean cuts, so I use them even for parachute cord. Turning the corner at the bottom bracket. I've snaked a lot of electrical lines and drain snakes. Drain snakes especially feed themselves with twisting motion. You don't need a 'thread' twist on the end. By turning the thing you are 'snaking' it will 'turn' into a bend, with a steady push it will turn the corner. For a steel frame.... a small push spring (open) on a rod to capture by twisting the cable you've snaked down the tube can work. Using the clamp to mark the length inserted is a terrific tip. Then you have an idea where the end is.
The noodle attachment looks neat. I'm just wondering what would happen if it took a hard hit and got bent or mangled out of shape, locking up the cable. The outer housing I think is much more resilient.
Great video. I thought it was a problem clamping the work stand to a carbon frame? Any precautions clamping on carbon tubes? Why not use PRS-21 work stand?
You could use the PRS-21 with the 1729 thru axle adaptor. However, the clamp was gently clamping. It was pretty much cradling that tube, not squeezing it. Carbon fiber of course is not egg shell, and if it truly could not even support the bike's weight when in a stand, it would be a bad idea to ride it. - Calvin
I'm looking at a gaint Talon it isn't internationally routed could I use a Dremel tool to cut a place for the cable to pass through in the bottom bracket shell
Hi there. Very nice tutorial. I have this Merida big nine nx edition and i'd like to install a pro koryak dropper post. I just wonder if that is possible because i'm looking at it in the internal routing, seems there is no access on the down tube to the seat tube
You may be able to use our ir-1.2 to route the cable through the bb section. You could also remove the bottom bracket to acheive this. Check with Merida to make sure there is room though.
Hi! If a dropper post is not working, I can use the bike without it like a normal bike or not? I found a bike but the seller says the dropper post is not working
Yes, likely. If is in the up position, it will very likely stay there. However, if the failure is an internal leak, it may creep downward over time, and eventually just fall.
Hi! I have a gravel bike and would like to install a dropper with internal routing. As it is not prepared for that, but has the di2 holes, do you think it might be possible to use them? Thanks a lot and congratulations for the channel
Many Di2 ports are too small to run housing through. But.... some are large enough. I would use your best judgment and make sure that you can install a rubber grommet to protect the frame and housing.
hello can you help me, I have a 2015 Scott Genius 740, on my seatpost that is syncross it says 31.6mm and 400mm, what is the 400mm mean. Will I have a problem if I get this Brand-X Ascend Dropper Seatpost, that has a diameter of 31.6 mm and a length 120mm and a size 410mm? thank you
The 400mm and 410mm is the length of the entire post. from top to bottom. Many Dropper post companies will show great dimensional drawings on there website as fitting a dropper is not as straight forward as a rigid post.
My fame does not have holes to route the cable internally but could I just take of the water bottle cage and put the cable through one of the two holes
The housing is usually a bit too large to fit through the rivnuts for your water bottle cage. An externally routed post may be the best option for you.
I don't see any good reason for running the cable head on the lever end. The opposite and run it on the post end is better. The problem is doing it your way u don't leave enough slack in the head by the lever before the tightening screw. Adjuster all the way loose if the entire post needs to be raised, they can't slack cable enough and it actuates the post when you sit on it it drops unintentionally. I had a mechanic do that just the other day and he hadn't set the post out far enough and I have no way of getting slack now in the housing and thus the cable because the derailleur cable head has no slack in it at the lever. That's the main reason you want to run the head of the cable on the post end and not the lever end.
Looks good....but why not use the old cable housing to feed the new cable through then take the old housing out. Finally replace the new housing over the new cable. By doing this the old housing acts as a guide for the new cable and the new cable acts as a guide for the new housing. I suppose there are times when this new tool is handy but possibly not here.
Yes, you could use the old housing, and that was mentioned. But when building a bare frame, or if someone just pulled it out, the tool is very handy. - Calvin
Much of this is plain logic, but offsetting the seat tube cable length by moving the dropper lever along the handlebar - that comes with proper experience.
To run new cable you can't connect to the old one and just pull it through.Just how would you get them connected and still able to run through the housing???? You can't do it.
funny, he dodged the question of "what OTHER tools to use other than park tools" to cut cable housing?" Hes not going to say, hes promoting Park Tools duh, not hack tools! haha.
What a great guy. Could listen to him for hours!

Great video. It's amazing how helpful/important proper zooming is; and how often other videographers neglect it! Thanks!
I do this about 3 times a week!! it's still interesting watching park tool guy do it lol

Thanks for the vid. I will use the tips when I install my new dropper.
Wow, super informative. I was planning on removing the cranks and bottom bracket to fish the housing but this might save a step.
My internal droper post cable is frayed and needs to be replaced this video helps thank you for your time and effort making this
Dropper posts come with plenty of disadvantages . The main ones that I see are the squish phenomenon , seal wear , play in the bushings and accessibility with some frame designs for cable line and actuator . Another one is removing the seatpost for cleaning .
Park Tool your videos are very clear and easy to understand can you please do a video on gyro installation for a bmx thank you
Great video Calvin- wish my workshop was as well stocked with tools!
@07:00 You have like no how tired I am after 1½ days of fiddling around my CF frame in order to get the wiring of a Shimano XTR Di2 into it without the necessary tools at hand to remove the bottom bracket for easier access to the internals. This felt worse than sleeving all the PSU wires of my main PC ( which, like this internal Di2 cabling, is something I'll never again be doing! )
I would "dab" with Calvin Jones any day of the week
A shopowner I sometimes purchase from stated that internal cable routing is neat but much harder to service , therefore he has to charge higher labour rates .
That internal routing kit is great. But 50$ for a couple of magnets and some thin wire?? Come on now! I will only need to use it once.
Yeah, Park is ridiculously proud of their tools
Just use some floss and a vacuum
Just use something else
Like most bike stuff it's going to be expensive. It's definitely over priced but if you do a lot of cable routing it's necessary. With a little ingenuity one can probably make a cable routing kit themselves.
Awesome video. Saved me a lot of time.
Just awesome as usual sir. I learn so much from you really appreciate you sharing the knowledge 👍
Great videos. I learn so much. You're the man Calvin! But please invest in a camera with better autofocus.
I love these, I apologize that I just saw this late haha
Great video. Really really helpful
Wow... excellent tutorial!!!! 👍👍👍👍
Excellent - thanks for another detailed and highly educational video. This man is a wizard :)
Thank-you great information 👍

Great clip but... why grey housing for all black bike? :)

My bike doesn't have any holes in the frame for routing. Is it ok to drill a small hole in the frame to put the cable through?

do you have a video on servicing/maintenance a dropper post. I have that exact one
Really great tutorial, thanks.

Never trust a guy who can keep his cool while internally routing cables
Great video, seat still seemed high at the end, but great explanation and how to do the job
What part number is that park tool brand blue tape?
:) No Park Tool branded tape unfortunately. Cheers.
Very well done video. Thanks.
Wouldn't the cable noodle interfere with the brake lever?
Calvin great Job like always Where can u find these cable ends ? Knarps ?
Loved the beginning :D!
What a nice video! Thanks!!!

We do not recommend modifications like that. Things can go bad and the warranty is void after doing such modifications.

what is kind of this cable/magnetic cable?
www.parktool.com/product/internal-cable-routing-kit-ir-1-2
Um... is there a reason you didn't pull a piece of string behind the old cable when you yanked it out?
Because he was demonstrating what most people will probably have to do - install from new, not existing.
Perfectly explained thank you!
I have a hydraulic dropper the process the same?
Your are the best !!!!
Fish ON! - Thanks
hello can you help me, I have a 2015 Scott Genius 740, on my seatpost that is syncross it says 31.6mm and 400mm, what is the 400mm mean. Will I have a problem if I get this Brand-X Ascend Dropper Seatpost, that has a diameter of 31.6 mm and a length 120mm and a size 410mm? thank you

How do you remove the seat post without cutting the cable?! I'm going crazy over here.
It has to have enough slack to be able to pull the post out and then un plug the wire to remove the post completely.
My fame does not have holes to route the cable internally but could I just take of the water bottle cage and put the cable through one of the two holes
The housing is usually a bit too large to fit through the rivnuts for your water bottle cage. An externally routed post may be the best option for you.
Leave that to the professionals. That's why they make the big bucks.
I don't see any good reason for running the cable head on the lever end. The opposite and run it on the post end is better. The problem is doing it your way u don't leave enough slack in the head by the lever before the tightening screw.

What if you have an aluminum frame?
Still works great. Steel frame is where things become an issue.
Awesome video! 少し？Sukoshi? :-)
I always use my Dremel but I don't like the results so much... someday I'll buy a good cable cutter
I got my frame for free would you recommend that i drill holes to route it internally, (i dont mind drilling holes)
SBM Crew I wouldn't recommend it because it can cause cracks and a weaker frame
Don't do it for gods sake!!
Will this work on an aluminum frame?
It sure will.
We just got rickrolled by calvin at the beginning
Can you do a video of a dropper post on a road bike
You are funny.Good video.
I'm considering moving my cables to the outside of my frame. Just so it's easier.
Which bike is that?
Focus Sam C
Or you can buy a lever that can attach the cable and put the shifting cable the other way. It will save you 90% of that work and fiddling.
720p?!?
The instruction were clear and concise but the music fading in and out was highly distracting
Who knew John Turturro's uncle was a bike mechanic.
Wait .. scatman is a bike tech ?
Looks good....but why not use the old cable housing to feed the new cable through then take the old housing out. Finally replace the new housing over the new cable.
By doing this the old housing acts as a guide for the new cable and the new cable acts as a guide for the new housing.
I suppose there are times when this new tool is handy but possibly not here.
What if building up a new bike?
i was thinking exactly the same,could get it jammed inside the tube though.
Just to have some FUN!!!!!!!!
Yes, you could use the old housing, and that was mentioned. But when building a bare frame, or if someone just pulled it out, the tool is very handy. - Calvin
Much of this is plain logic, but offsetting the seat tube cable length by moving the dropper lever along the handlebar - that comes with proper experience.
Okay,.. but what if you don't want to spend 50$ on a piece of string and some magnets. How do you do it then?
if its too short you cant get it in
Nice video and content shame about the camera skills with to much movement. Made it hard on my eyes.
I feel bad on the top tube clamped down and dropper post got pressed down
That's new longest video

Why not attach the new cable to the old cable before you remove it. Then when you pull the old cable out it pulls the new cable in.
To run new cable you can't connect to the old one and just pull it through.Just how would you get them connected and still able to run through the housing???? You can't do it.
Bladder control... 🤭
