I show the process of removing the old trigger shifters/brake levers and installing brand new shifters/brake levers along with new shift cables/brake cables and housings. The bike is a Trek 4300 mountain bike.

The great thing about videos like this. Is that they help people like me who live in an area where there are no bike shops.

I just bought this same exact bike for $25 as my first mtb bike. When I showed up to pick up the bike all the bolts and cables were rusted, and every black part was faded from the sun but the paint and chain and gears were in great shape. Bought new cables, soaked every bolt in evaporust and sprayed every black part with black restorer spray and got her looking brand new. Watched a couple of your videos of how to do maintenance and the bike runs so smooth now. Spent a total of about $50 and I couldn’t be any happier. Thank you!

6 years later after release, I watch this video for the 1st time and it taught me a lot!

[@thinkclear3834]

Yea me too

[@MASH--kn1cw]

I actually just found the exact same bike for $120 last Monday, April 16th! The guy I bought it from bought it new in 2005, rode it 50-60 miles, parked it in his garage and never touched it since. I brought it home, wiped it all down and realized it was technically still brand spanking new! The only thing that I have replaced was the chain, I put a nice 10 speed chain on it and shifts so smooth. It's definitely a great 24 speed bike, hardly any scratches on it and the shocks work like a dream...shifts like a dream and definitely looks like it came right off the showroom floor. Even the shifter gear indicator windows are still clear as glass. No yellowish tint whatsoever, not bad for a 13 year old mint condition Trek 4300!... I love this video as well as all of your other tutorial videos, I've definitely got alot more love for bikes and bicycling because of you. Keep doing a great job and never stop biking and repairs. Thanks RJ!

[@Eddie_Cue]

Thanks man very helpful. The bike shop wanted to charge me $179 where I purchased the parts on ebay for $49 and did it myself. Cheers again to you!!!

[@hewer1953]

Excellent video. I’m changing the trigger shifters on my 7 year old diamondback bike . With your video help I changed the front derailleur and have my brakes adjusted perfectly. My next job will be to true my front wheel . I ride a mínimum of one hour 4 days a week in my retirement. I believe I would have to park this bike without your help Thanks JR

[@Ishmayah]

This video solved the problem with my Trek 820. Thanks a million!!!

[@jimson7070]

[@euripedesmariano8514]

bom também

[@lkw5699]

Thanks to your diy video I attempted new shifters myself. I love how you showed us how to troubleshoot adjusting everything

[@tonypotter9578]

Great video and really useful. Just in the process of re cabling the derailleur and replacing the brake levers on my 1990 Diamondback! 👍

[@thesuperzfamilyvlog6607]

This is a wonderful video, I've learned so much. Thank you for this. Now to tackle my daughter's bike.

[@shambelgelan3272]

If i tough a bike video this is the best

[@JOs9gOmEz]

Thanks for the video! Learned a lot! I was a bit scared to replace my own shifters and now I feel like an expert thank you!

[@zoes8785]

thanks man, hoping to replace my shifters and cables this afternoon, will let you know how it goes! update: bike is fixed!! i bought it really cheap off someone else, and now with the help of your video i've replaced what i need to, and it works well!! in total i spent about $60 USD for the bike and parts :) thank you legend!

[@RJTheBikeGuy]

Ryushi Shiratori, you generally want to have them on the smallest gears when fitting the cable. An exception is a Shimano Rapid Rise rear derailleurs which you would have the chain on the biggest cog when fitting the cable.

[@sovereignentity4924]

My Favorite Bike Guy...! Awesome detail..! Thanks RJ..!

[@greypeter]

Thanks! Very clear and informative, as always. You are a great resource for the home bike mechanic.

Thanks for making this video. Had a catastrophic failure of the rear shifter cable (it literally burst out of the shield at the bend) and was able to replace and adjust the cable thanks to your video. Much appreciated.

[@albertokusmic9239]

Very clear and complete explanation. Thanks for sharing!

[@orbital..4809]

It's easy to visualize how to do it but man i keep forgetting where to use those little components attach to the start of the shifters. Thank you for helping me much man

[@lucianonarno1408]

That's a very nice looking trek! I already have 2 road bikes and one cyclocross bike, all three from trek. I'm looking for a Trek MTB now. That grey/orange combo is one of my favorites for paint jobs!

Excellent vid on the subject, now I can say that I too can do those things!

[@domadiful]

Dude your videos are the best!!

[@the_blair_bike_project]

Holy cow That's exactly like one of the bikes i just bought used and finished getting it running nice. The other one i bought was a bit of a Franken-bike. Messed up on the shifters. (Lost a spring) waiting on new parts to arrive.

[@respekt200]

Exactly what I need

[@SuperJohnfoster]

Its so easy for you . I do it and its 3 to 10 tries on shit before its even close. You have been very helpful .

[@lewiburke8702]

good video great explanation

[@angrahell]

Thanks for the excellent video!

[@ainteyebad]

love your vids man keep it up!!

[@MelSoCal2011]

oh man! you made that look so easy and here I am struggling, about to light a match under my derailleur!

[@RJTheBikeGuy]

+MelSoCal2011 Take your time. It's not really that hard.

[@ChiefofTradez]

Wow i should have bought Trek 820 or Trek in general. I bought a GT Agressor 3.0 today from craiglist. 1st bike and its in poor shape. I was discouraged and thought i should get my money back. Like that will happen. The brakes are shot. The gears dont shift that well. The shimano gear shift is missing its tops. The gear lines are exposed and rusted. Chain rusted and rear derailleur needs replacement. Then i see your video and im actually looking foward working on this bike. Thank you sir. Great instructions and camera angles.

[@RJTheBikeGuy]

Tommy McCabe I have bought a few bikes like that.

[@williamgray7130]

Here's a trick that might work: When trying to hold your brakes tight on the rim to tighten new cable, try using a plastic cable tie around the pads. Snug the cable tie up tight, pull the brake cable and tighten the hold bolt and then simply snip the cable tie.

[@n_u001]

William Gray or u can use a rubber babd or a hairtie. I use those as a e brake so it doesnt slip or roll down the hill when stationary

[@BB.EDITIZ.227]

Thank you brother 🥰🤗🤗🤗

[@pakasitj9968]

Very useful, Thanks

[@joeh690]

so much work but you make it look so easy

[@finally7664]

Well done 👍 Sir.

[@MrLeiduowen]

I like work; it fascinates me. I can sit and look at it for hours. :)))

[@the_fitness._freak]

I am from India thanks for the video

[@justme9246]

Thanks RJ enjoy ur videos good work ;)

[@FallNorth]

Another tip that might help is: If you find you need 3 hands to put the brake cable in (I do as a stripped the alloy and now have a bolt through with a steel nut on the back) - I sometimes put the cable into the clamping bit with the noodle OUT, but I've made an estimate as to the correct length. I don't tighten too much, put the noodle in, see if it's about right, then if I need an adjustment take the noodle out again and move it say 8mm or whatever then tighten it up and put the noodle back in. Also popping the noodle is a great way to give the brake blocks a good clean, they get that black film on them that affects braking.

[@johnhopkins6565]

2:15 try hairspray, works as a lubricant, and an adhesive.

[@johnhopkins6565]

12:55 you can also use small diameter nylon sleeve or even fuel line to isolate the cable from the top tube. My repair stand clamp is hell on that raw cable on my 950.

[@johnmasters1667]

I was wondering how you inserted the shifter cables into the intergrated shifters

[@IdahoNick1]

Thanks so much. I learned so much watching this video. I'd like to know more about where you purchase supplies such as the cables and housing.

[@RJTheBikeGuy]

Amazon.com usually.

[@ryushishiratori2312]

I am replacing the shift cables on a 21-speed bike. Do the gears that the front and rear derailleurs are in matter with concern to proper fit?

[@socraticproblem86]

Thank you for this tutorial. I am looking for a way to repair my brakes. When I squeeze the brake it doesn't do its job well. I can't go on knowing not how to replace brakes.

[@roncooke2188]

Hi many thanks for your interesting reply noted

[@omelas4]

Great content! Is there a way to replace the break levers only but keep the shifters?

[@cstrike105]

This video saves me a lot from having brake cables installed in a bike shop. Buy a 2 USD brake cable and DIY install on both front and rear brakes.

[@blaubeersauce353]

Thank you very much, this is most comprehensive and well done. I just miss the part how to insert or remove the cables from the gear lever? Mine has kind of screws that wouldn't open the housing. P.S.: Well, another video suggests just to pull through the loose end. In my case the cable got stuck and the front gear shifter is in an ill position. Can't see the reason as the cable is entirely covered by its housing. I think I should undo the lower end and then try to get the upper part through, if you get me. Sorry for my English, by the way. Good luck!

[@copple_mx7252]

That would look really good with those rock shox Judy s

[@TheIanthebean]

brilliant

[@ayush2440]

Can you make a vedio on how to change the whole gear set of the rear wheel

[@madisonjoyce5964]

Cheap is an understatement. A bicycle part can be shop quality made.

[@McDonald1331]

thanks

[@copple_mx7252]

rj that bike needs those Judy xcs

[@jdhshddisalex2488]

good joob. really nice video

[@user-hy8ht7xq6i]

nice video

[@curbowman]

I have a 7-speed bike but the only integrated shifter/brake levers I could find is for 8-speeds. Can I use them with the 7-speed freewheel or it's better to replace it with an 8-speed one? Thank you!
