Smooth shifting gears make bike riding a pure pleasure. There is nothing worse than a slow shift or missed gear change at that crucial moment. Ex-Professional cyclist Simon Richardson explains how to change your gear cables on a Shimano equipped bike so you get silky smooth gear shifting.
It is important that the outer-cables are the correct length. If they are too short the will have increased friction as they will bind when turning your handlebars. Too Long and they won't just look untidy, they will also have increased friction as they are inside the housing for longer than required.
After cutting the outer-cables to length we cannot reiterate the importance of making sure that the ends of the outer-cable are as circular and flat as possible, remembering to ensure that the liner is not squashed. This allows the inner-cable to enter and exit the outer-cable as smoothly as possible.

Leave your tips on how to fit gear cables in the comments below 👇
The easiest way is to buy Sram Etap.
If your shifting cables are exposed where they run under the BB shell, it is better to use 2 pieces of the guide liner tubes, one for the length of the chainstay and the other one for the downtube. That way it will be easier to add a short piece of the liner to protect the exposed length of your cables from the elements.
Global Cycling Network you should delete the older videos and remake them

Use a really sharp axe (or machete) to cut the cable outers. Makes a very clean cut
Change your cables regularly, even if your derailleur seems to be shifting fine. Then perhaps you won't end up with a broken rear derailleur cable and no rear shifting when you're 15 miles from home (like I did last month).
To prevent your housing from crimping when cutting it to length, I run an old gear cable through, and then cut it.
Useful tip,Thanks man
Carmen Marin Smart thinking!
good tip Carmen. that's of Lasty's tricks too. Jon
Great tip, but I'd use a cheap bit of new cable to avoid contaminating the outer.
Carmen you seem knowledgeable, do you suppose a Dremel would give good results for cutting cables and housings to their proper length or should one invest in one of those specialized cutters
Perfect instructions. I did my first internally routed rear derailleur cable replacement today, using this video, and it was all the guidance needed. Even used a Canyon bike... :) One interesting difference was that the original cable inner came out with a plastic tubing sleeve for the internal run - probably stops rattles and keeps it cleaner under the bottom bracket exposure. I refitted it on the new cable (only did the inner, as an urgent fix). I used a length of 1mm teflon tubing I happened to have - just the right diameter for the job.
Am I not watching carefully enough or you really missed the step of taking out the old cable out of the shifter?
I had endonsctews on front shifter and fiddle round screwdriver get end cable out czcams.com/video/mk4loTTsemA/video.htmlsi=-wg-YqHKphJHVRtu
If your cable is still good you don't have to change it
Isn't it obvious that you'd remove the old cable?
Missed the step of pulling the old cable out? Just find where the cable goes and take it out. How hard do you think it is?
GCN a great help, didn’t know there was so much to learn about bikes,,,, quite technical these days, keep up the good work chaps 👍
Thanks for the video.
Here's a tip:
Bar tape still good, but the adhesive is too strong? Bar tape tearing as you unwrap it?
Use a hair dryer on the handlebar as you lift off the tape. This softens the adhesive and helps it release. This will prevent tearing the bar tape and hopefully allow you to re-wrap the flats with the existing tape, good as new.
I hope this helps.
I haven't got any hair.
Snapped the rear shifter cable last night! Luckily had a spare set ready in the drawer and this gem of a tech video to help me out. Perfect!
Hi fellas
I'm new to cycling and love all your videos, they are very informative for a newbie like myself. Bikes have come a long way since I was last on a bike as a kid so keep up the good work. 👍😊
Thanks for this video. You saved my day and love the park tool cable cutter.
Worst thing about these videos is they make me want to buy 4 figure bike, that Canyon is gorgeous!
InvadeTheAirwaves but the neutral service canyon looked better lol its like those bike u ride that can get people's attention
Only that you mentioned "troublesome downshifts" helped me solve my problem as I could not shift to the biggest ring of the cassette. Turned out the cable was torn inside the lever! Replaced it and everything is perfect now! Thank you!
I'll give it a try. Thanks for the video!
Can I just say.... @simon - you have given me the confidence in taking on more repairs etc on my bike as opposed to leaving it into my lbs although for the real difficult jobs I'll obv leave to experts.
Great video - gave me the confidence to tackle replacing internal routed cables which I thought was LBS stuff - Clearly explained method - thanks
Excellent presentation.
That cable trick for the routing was awesome
I have a smattering of Sturmey Archer 3 and 4 speeds across my fleet and my rule is to only change a cable if absolutely necessary. it's pretty tricky to install a new one without having to live with ugly pinch bolts. My oldest gear cable is 39 years old and still going strong.
Woah! Cool seatpost!
Excellent stuff, feel confident to have a go myself now ☺
what size is the plastic tubing used to guide the cable internally?
Great video. I chuckled when he lists all the tools without mentioning Allen wrench; first tool used: Allen wrench.
he was only listing “specialist” tools. :)
Best Video out there. Thank you, Simon. 😃
What a great presentation. Pro voice and pronunciation quality.
really helpful thx
Great video! Basically never had repaired anything on my bike myself and I could do it - one tip that was missing in my specific case: to check if the end of the old cable (the little metal knob) is still in the shifter in the handlebar - was the case after I had wripped the shifting cable - had to remove the bottom of the shifter to get it out of the system
I have the same problem, but can only see the frayed end of the old cable. pulling on it with pliers doesn't get it out, it's stuck. Is there a trick to this?
Thanks, good tips!
That is a beautiful bike...
Si, king of the bike wash!!!! Working on a dirty bike!! How could you!?!
Trifit racing Seldom seen a bike so filthy. Disgusting.
That bike is gorgeous😍
Works good
That is the quality i love.
Great video.
I love this bike so much. Btw you couldn't be more right about the quality cable cutters, I can't count how many cables I've ruined with cheap cable cutters.
Hello from Brazil Simon,
Nice video, as always!!
Please, can you explain what are those plastic grooves (5:47min) that you insert in the cable before routing it into the shifter?
I have got a new Shimano Ultegra R8000 kit and it came with some of these groups.
It is the first time I'm replacing a complete group, so I'm in doubt about these little things.
Thank you and best regards.
Marcelo
Easy job - "piece of cake" - thanks :-) ...also small hints of good maintenance ideas :-)
The GCN Tech channel is a long but useful rabbit hole!
excellent
A good video. Please, could you show the procedure for changing the cable for the left shifter - the two ring gears? You now have two videos about changing the cable for the right shifter. For a somewhat "feartie" at bike maintenance, a video dedicated to the cable that operates the two rings would be a great help.
A head torch is also good. Heads up on the Flight, Podium 1, black and white model, the internally routed rear gear cable in the down tube does not need a plastic inner sheath to guide it (the exit hole at the bb is so small that it dosnt fit) putting the inner cable straight in works
It would have been good if you elaborated on routing around the head tube (criss cross) or direct.
It's crazy how many bikes are set up OEM with the cable housing mashed against the head tube after exiting from the bar tape and taking a sharp curve to the same side of the frame. This is simply stupid. That bike manufacturers aren't routing cables this way (right cable to left side of frame, and vise versa) at this point is almost criminal. My LBS showed Cannondale this trick 25 years ago, after which they made this SOP for their builds. (We also taught them how to overhaul the Headshok, but that's another story.)
Спасибо огромное! Искал как заправить трос переключения в дуалы сора 2017г. Оказалось так же, как и на дюрейсе на видео ))
Where do you get the tube to guide the cable through the frame?
@@jamiesurfs , been wondering the same thing. I think these liners would work, just a guess. You can find them on Amazon too. www.worldwidecyclery.com/products/jagwire-slick-lube-liner-for-elite-sealed-shift-housing-kit-4-x-2300mm
I bought a 2m length of outer housing and stripped off the outer casing and steel reinforcing leaving a thin, blue plastic tube that worked perfectly.
The jagwire liners do work perfectly. Just used them myself 👍🏼
Yes i like to put oil on the inner but only fitting cheaper cables some times
hey GCN, any chance of doing a video on how to protect your Aluminum/Aluminium bars from corroding due to sweat over time?
2:18 - so nice to see a GCN-fleet bike that isn't pristine clean, and instead looks like it's seen the abuse some of our bikes see. ;-)
Thank you so much, but please can you tell me why the rear derailleur got to two index adjuster, one in the derailleur and the other in the handle bar where the shifter are, so can I use any of them or??? , thank you in advanced for the reply!!!
Any detailed videos on replacing the front Derailleur cable? I totally messed up the L/H screw starting positions and cannot seem to get it to index correctly through all three front gears. I am starting with the smallest front and largest back gear.
A genuinely informative and well thought out video. Please take note GMBN, less filler, more quality content. Canyon and those other lucrative sponsors will thank you for it.
Where do you buy the thin white tubing to route the cables through?
I'm trying this tomorrow, looks a very clear video. But how did the clear plastic tubing get from the top of the frame all the way down inside the frame and exit at the rear mech? Did it just push through when the cable itself was fed into the frame from the bars end? What happens if the tubing gets stuck midway?
Nice. What is that seat post? I'm guessing it's a vibration/force dispersing post?
Thanks, as always excellent videos with only the best relevant information. I live in Australia, does anyone know where I can get the inner sheath you used to ease guiding the cable through. To date I've been using fishing line but much prefer the tubing you use.
For those interested in getting the sheath to feed the cable through. Get a length of outer, strip it down (remove plastic, wire surround) and hey presto there's a perfect plastic tube inside!
Great, thanks. Now what about the front cable and barrel adjusters?
Where do I find the thin plastic tubes?
Yea really good to the point video. I need to replace my rear shifter cable. Where do you get the thin plastic tube that you use for the sleeve to slide the new cable back through. Thanks John
I ordered a 4 meter long piece off amazon, I believe that same sheath/tube is the innermost layer of a cable housing if you feel like stripping everything else off an old piece you’re removing
@Bon Scott the description lists internal diameter as 1.8mm and external as 2.6mm. It’s worked for both brake and shifter cables

Great Beginner Bike
I've heard you can use a vacuum cleaner and cotton string if you need to feed through a frame. Put the vacuum at one end and vacuum the cotton string through the other.
for me i just make sure that i dont remove both the old inners and outers at the same time. So i'll have a guide for the new inner or outer to follow when i install them. Haven't really seen a need for the plastic tube method shown here
Any idea on the dimensions of that plastic tubing? I guess the ideal id would would 1.3mm but what about the od?
which shimano cable kits come with the coating? or how would one kno which to lube and which to not lube
@6:33 seems like every single video on youtube about installing shifter cables glazes over or doesn't cover at all the one part that I'm personally stuck on: how exactly do the ferrule pieces connect with the shifter mechanism? I can't get mine to go back on properly and for some reason, no one shows this, the only part of this whole process that's tripping me up.
Im dreamig to have bicycle like that omg
Two critical pieces of info missing from this and the rear derailleur adjustment video I just watched. One is to pre-stress the cables after the initial installation (and before doing the indexing adjustment). Doing so seats the ferrules and gets rid of so-called "cable stretch," so the indexing adjustment will remain constant and not need a readjustment later on. Two is to check the hanger alignment before setting the limit screws and indexing, because without good alignment, no amount of adjusting will ever work properly.
How does one prestress?
@@unseriouscycling5751 With a cable puller/stretcher
It could ease a bit the process for rim brakes but it makes it a lot easier for front and rear deraileur!
@@nounours2627 Bicycle derailleur cables are typically pre-stretched by the manufacturer, and you should not need to pre-stretch them before installation. Manufacturers pre-stretch these cables during the production process to reduce the amount of stretching that occurs when the cables are installed on a bike. This helps ensure that your gears shift accurately and maintain their adjustments over time.
When you purchase a new derailleur cable, it should be ready for installation, and pre-stretching is unnecessary. Simply install the cable according to your bike's specific setup, adjust your derailleur as needed, and ensure that the cable is properly tensioned.
If you're experiencing shifting issues or suspect that your cable has stretched over time, it's more likely due to cable wear or the need for adjustment rather than a lack of pre-stretching. In such cases, you may need to replace the cable or make necessary adjustments to improve your bike's shifting performance.
Yeah I'm taking my bike to the shop.
can you guys share some information on sora r3000 and claris r2000??
Awesome tip on using the inner sheath to make rerouting internal cables easy! FYI, I'm having fantastic results with Jagwire's teflon coated cable and compressionless housings - silky smooth action.
Also - for those doing this job on a bike they got from a shop or on order: You can almost always shorten your housings which will result is somewhat less friction (small difference). Shops will nearly always build with 2-3 inches or more of unnecessary housing length. Just be careful not to go too short as they cover here at around 4:50.
Always file down the end of the cable, I filed the end of the cable and waala it went in without the cable fraying.👌👌👌👍👍
If you happen to lose the small metal item that crimps to the end of the cable, you can always substitute an electric wire connector. They come in a variety of sizes and cost about 1/10 as much as an official end piece,
I am replacing the cables and bar tape on a 70s steel frame road bike, and the cables were originally routed separate from the bars with a lot of slack, should I just use the new cable to figure out how to route it and cut it when I have the right length for it to go under the bar tape?
#1.Does it make any difference if the chain is on the big cog or small cog when attaching rear derailleur cable?
Shimano Dura ace cables. Would they fit Ultegra shifters (ie dedicated the dedicated ferrule with the notch in - is it the same for Ultegra?)
thank you for saving me 60 bucks mate. my LBS wanted to charge me a basic tune up price to install the brake and shifter cables, even though I am supplying brand new shifters and brakes with the cables already installed in the device itself ( its a 2 in 1 shimano tourney I am trying to get an old Giant rincon I found at an estate sale road ready because the cables were rusted and exposed)
Where can we get the thin plastic tube from ?
I hope I can have a road bike like you guys!!😢😞
Amusingly, it's almost impossible to get hold of that Shimano 9100 cable pack in the UK from any of the usual sources. I had to get the small outer for the rear mech from an ebay seller in Taiwan!
really really want to do this (since the LBS has a 3 week wait for any services) but just think it's more complicated than it looks in the vid.
Timely as I'm about to do just that.
I live on the coast in Oz and the cables need servicing more often,a bit of Rock N Roll (blue) on the cables makes all the difference in longevity.
Quick question.. i am fitting Shimano grx shifters... do Shimano left shifters always work with the front derailleur & right shifter always work with the rear derailleur? Appreciate any advice... D
What size cable do I need for my front derailleur on my 2018 Marin four Corners
My Jagwire housings have the little inner wires poking out the end near the derailleur. Is that a sign the outer housing should be replaced or should I jam the little wires back in?
Hi :) I would like to change my 105-5800 groupset bike(Cannondale CAAD12) stock handlebar into a Pro Vibe Aero with internal routing.The problem is that I need to completely remove the shifter cable to connect the shifter and brake cables trough the handlebar.The brake cables have in the shifter end a crimped part.It’s possible to cut it down and replace with a new one?I don’t want to remove completely the cable and the housing just to get trough the new handlebar.(Remove the ends in the shifter and crimp back that round part,and get them back to the new handlebar)
My bike has the inner sheath originally installed, should it be there or just the guys in the factory forgot it there? Should i re-install a newer one or just remove it?
Does any know the best way to find the right cable lengths without the old cables?
Currently at the cabelling stage of a complete rebuild, so I don't have the old cables 😬
Awesome vid as always, but would you know where to get that thin plastic tube to lead the new cable through the frame? I can’t seem to find it in any shops.
Great video, and I'm very pleased with my new GCN bottles!
Maybe I'm just lucky but I have never had any issues guiding cables through my frame without a plastic tube.
hope you are staying nice and hydrated.
The previous generation 11spd doesn't need that special piece of cable housing (rs900) for the rear derailleur. That is designed for the new derailleurs that have much shorter cable routing to the frame...
Question: If my shifters are broken (crash) and I want to replace them. I need to redo the cabling. how do I get the bike in the smallest gear without being able to use the shifter on the handlebar?
I was having trouble, only in in cold weather, with the three biggest cogs skipping around, despite having changed the cassette and chain fairly recently. In desperation, I thought I'd try changing cables and housings. I had to use the magnet trick on the rear cable, and had some challenges with the internal routing housing on the front, but complications were overcome and lo and behold all the gears work well, and overall performance is noticeably better. I had no idea how much performance had declined over 5 years.
Typically, when experiencing shifting issues "only in the cold weather" it's a matter of lubrication, even inside the hand shifter.
Can i use a regular diagonal pliers if I do not have the special cable pliers?
I see what you mean about the thin plastic tube but no sign of it on ebay, everything but. interesting video helpful
sorry, if I want to change my standard handlebar for an aero bar internal cables, do I need to replace whole the cables ?
My rightside shifter shifts no more and I can't shift the rear derailleur into the cassette bottom smallest gear. The bike is stuck in the top largest top gear. Should I still cut the cable and continue to remove and replace the old cables and rightside shamano altegrau st 6500 rightside shifter with new shamano sora 3500 right side shifter?
Hello. You didn't show which berrules use where (there are two types of them) and why cables are in blue and white plastik bag? Which is which? Thanks.
How can I purchase the thin plastic tube? What name is it sold by?
Any recommendations for the dimensions of the small tube to run over the internally routed cables?
just google innerliner
Does anyone know whats the measurement of the plastic tube he use for the cable
Can you re-use the cable housing?
Clicked so fast cos I was waiting by watching gmbn cos watched nearly all gcn videos
i'm lucky with my bikes, the whole cable routing goes through a cable housing even when internal so no need to fish for the cable
