NO! I will not buy cable snip. To get a good cut on the cable, I just use the cut off wheel on my dremel tool.

[@RicardoPetrazzi]

5 years on, still the the most concise and well presented video on the topic around.

[@Robinators]

it is all easy peazy, after watching 100h on youtube on how to do it :D

[@hopenavajo1391]

I didn't think I'll replace cable with hydraulics. Hydraulics is expensive and messy, unless you want to keep changing when cable is better. With cable you don't to measure how much to fill the right amount and cleaning up afterwards. I rather stick to cables,than hydraulics.

[@Gav_s_dh5]

Can’t u just re use the outer cable ?

[@kalijamies]

I use heat shrink (the one with adhesive inside) instead of those nasty cable caps. Crimping freys the cable. If the cable cap comes off the cable end if going to frey. With the heat shrink with adhesive the cable stays in tact and the heat shrink doesn't ever come off on its own.

[@LongLiveEnduro]

Unfortunately one of the most difficult things is missing: How to replace the outer with internal routing.

Deraileeeer????

[@netac7667]

Am I the luckiest guy on earth that every time I got a problem, GMBN will upload a video "How To" for the exact problem or maybe I am the least lucky guy In the world since I have so many problems with my bike...?😂😣

[@sbbeowulf8296]

I messed with my cable and the little barrel thing and it got really tight and now I can’t shift to all my gears because it’s too tight now I feel like I need to replace the cable

[@Kschtokes]

This is one of the most thorough videos I've watched. Really good.

[@banacek60chord43]

Excellent: thanks a lot. The mysteries of the shifter internals are revealed. Essential tip about the solvent/spray grease do's and dont's.

The timestamp

[@MilatovichFamily]

Thank you Doddy! You are the tech master! Liked as always!

[@mikewestgarth9610]

Followed this video after having problems with the rear derailleur cable and after replacing it all works perfectly now! Cheers

[@dubbaluga]

Thank you for the informational video. It really helps me with repairing my bike!

[@jamesmcbride6178]

Super video, just helped me replace my cable. Thanks Doddy!

[@cheekymunky80]

Picked up a gear cable set from ChainReaction, everything for £13 including some beauty little sleeves to prevent frame rub. followed this and was done in less than 10 minutes. Didn't realise replacing the whole cable was so easy.

[@NirreFirre]

Very comprehensive and clear, good one Doddy!

[@HeavyBill989]

Thank you thank you thank you. I just got my bike back after a service and the rear shifting was awful even with adjusting the barrel adjuster. Rather than try and arrange to take it back to the shop which is 15 miles away I watched your video. Turns out the cable hadn't been pulled through at the derailleur properly so a wee adjustment and the gears seem to be fine now.
