RJ The Bike Guy what if it isn’t on the wheel

[@dominicbenitez3612]

RJ The Bike Guy I don't know if you will respond right away 🥺I have a question for you 🙂 and it might seem off topic for this video

[@dominicbenitez3612]

Here we go 😁 I have a similar BMX bike to the one that your display on the video except the bike feels kinda to small for me the type of bike I'm riding is a Redline MX 20 the year I'm not sure it ranges from 2004 to 2007 8 ish

[@Toto-is8ci]

My first BMX rebuild with out a chain in it. I really love the details, like measuring the width of the sprocket. Thanks a million RJ, you have really upped my game on repair and rebuild of bikes for our non-profit that gets used bikes to kids. The used donated bikes are so much better quality than the new box store bikes!

[@McNateDoggYT]

They always are better built than bought keep up the great work. People like you keep this world revolving thank you!

[@ocleirigh86]

Whenever I have a little job to do now, I don't Google 'how to xxxx'; I just search 'rj the bike guy xxxx', and you always have it covered - thanks pal!

[@frankcastle7299]

Finally a video i can understand. Thank you 👍

[@oxforddon2210]

I followed your great advice and had success sizing a new chain on my old 3 speed internal hub bike.

[@angusbrown325]

Your videos are so good because you include everything that someone needs to know to do it right, and they are structured in a very understandable way. I just wish I had found your video on disassembling a Sturmey Archer Dynohub instead of the random one I found - then I wouldn't now have a Dynamo ring magnet with no magnetism! I have learnt my lesson; I check you videos before going anywhere else!

[@adrian_V99]

RJ is highly knowledgeable. No hype, no gimmicks. Saved me a chain which would have been cut too short. Thanks!

[@AntzBoogie]

Thank you for always helping us with our Bicycle projects! I’m currently converting my Cannondale Mountain Bike Frame to a Single Speed EBike and this is one of my final steps and I needed a refresher lol. Thanks again your videos are awesome and very descriptive! Better detail then most of the videos I find!

[@SonnetGomes]

Thank you so much for posting this very helpful video. It helped me understand chain width measurement.

[@wanted-33]

Thanks again RJ, another helpful video for a shade tree bike mechanic.

[@carlosamador8085]

Awesome video RJ!!

[@skyelee9398]

Short and simple. Plus good quality video. Thank you

[@cocomolokobigsis]

You saved me a bunch of trouble. Couldn’t figure out what I was doing wrong. Hadn’t thought to move wheel back. Well I learnt something today!!!! Thanks again

[@damianwestcott8885]

You are very helpful learnt another great tip today on how to install a chain fantastic..!

[@Patrick-ci3lc]

Thanks for this video. It was incredibly clear with really helpful video. Your wire hanger tool was genius allowing me to experiment with chain tensioning on a conversion with vertical dropouts.

[@SilverShadow2LWB]

Very nicely explained. I like the fact that there was no crazy music in the background. Thanks

[@skorpiolovesmith]

This video was extremely helpful! Thank you so much!

[@cletisklump]

RJ, THANK YOU ! I just followed this video step by step with great success ! I have a sweet single speed and added a 20T cog to the back wheel and put on a new chain. First time ever using a chain breaker, I felt so empowered…lol ! Your instructions were spot on ! You have a new subscriber Sir !

[@pipanche]

Best chain video out there, thanks!

[@chillridesjohn]

Thanks RJ, your videos are very helpful!

[@Soundafek]

That was EASY!! thanks RJ.

[@kellygoodbrad8104]

Such a well done video. Thank you.

[@themickey3838]

Thank you, Thank you..... so easy and could not find the answer on google just forums with questions, finally led me here

[@BikeDispatch]

Nailed it. Thanks 🇳🇿🚴🏻‍♂️

[@Matthewmm110]

Thanks man you are way better than park tool I just hate watching their stuff they make it so complicated

[@sethvanheythuysen4039]

Very usefull

[@BerserkerNick]

Can you please do a video on installing a half-link chain

[@sophiejose4872]

Thanks!!!

[@jeffro512]

That 2” piece of wire is GENIOUS

[@devinbyrnes8058]

I just bought a bigger freewheel but the stock chain had barely any slack. This is helpful. If I need a chain, I know what to do.

[@evanszikun5307]

learned this the hard way

[@standupforwhatsright4168]

What size chain goes on a vintage predator 20" bike with freewheel??

[@tomkruze2749]

**** Is that an Mid School Trek sub Vert BMX Freestyle bike? My buddy had one in the 90s same color. Can’t see the frame that well to know for sure…

[@GLedesma]

I wanted to ask, I have a steel trackbike that I want to fix some bigger tires on it. I want to slide the rear wheel as far back on the horizontal dropout, but someone mentioned that adding too many links to a chain will weaken it. Have you ever experienced something like that? Thanks for reading this, hope it made sense!

[@RJTheBikeGuy]

No, adding a couple more links won't significantly weaken the chain.

[@formedmtb8367]

After u installed it was it easy to take the chain off the sprockets to get the wheel out?

[@RJTheBikeGuy]

Yes.

[@boltonyt9253]

Need help figuring out chain size for my 2006 trek tr30 help would be much appreciated

[@RJTheBikeGuy]

Go through the video.

[@jermstolibas4074]

i think you save my life lol

[@OjStudios]

Nice video as always. Sometimes there's a problem with chain tension which is the following. Older worn out cogs are not fully round anymore, so you need to find that point and set chain tension according to that point. If you set tension on the lowest worn point, it will be too tight on the higher/warped point.

[@RJTheBikeGuy]

Or replace the cog/freewheel.

[@OjStudios]

It's safest and easiest method. Not always possible though. If the repair can't cost anything.

[@RJTheBikeGuy]

A worn freewheel will wear out the chain. And vis versa.

[@OjStudios]

Yea, I know that all too well. I always change parts on my own bikes regularly. There just are some people who don't care and don't wanna spend any money on repairs.

[@DonovanBryant92]

can u put the pin back in? because if not then all my bikes need master links

[@RJTheBikeGuy]

If you can get it back in, it will never be as strong as before. The chain will likely break at that spot. Some Shimano chains take replacement pins. I prefer master links like KMC's Missing Link.

[@fordgt489]

What's that mm reading tool called? I need to figure out my chain size.

[@RJTheBikeGuy]

Digital caliper. www.amazon.com/exec/obidos/ASIN/B000GSLKIW/ref=nosim/youtube25-20

[@fordgt489]

RJ The Bike Guy Thank you very much.

[@justinehalili3313]

How to change free wheel sprocket to a fixie sprocket cog pls make a video

[@RJTheBikeGuy]

kzbin.info/www/bejne/qXrRmp1_ZtulaZY

[@AvatarFosco]

4:20 Why can't you put the pin back to make the chain longer again? Lets say I want to remove the chain for cleaning the bike. Is the chain unsuable then and do I have to get a new one or can I put the pin back into the chain to use it again?

[@RJTheBikeGuy]

Pins are not designed to be reusable. The chain would likely break at that spot at some point under torque. You would need a new pin, or I prefer a master link.

[@AvatarFosco]

Thank you! I think I will go for a master link.

[@maybedos]

unless you have a chain like a 510H with those riveted pins they can go without a masterlink I used to do heavy street and grind my chain heavily during sprocket grinds never popped out but for a KMC 410 or a bell chain never ever try to re pin it, It will pop off since the pins are not riveted.

[@hitokiridm]

measure twice, cut once. Got it.

[@David-np4vo]

Can i run a 1/8 chain on a 3/32 single freewheel..

[@RJTheBikeGuy]

Probably. Getting a 1/8" freewheel might be better though.

[@David-np4vo]

White industries 16t only accepts 3/32 but 17t on 》》 accepts both

[@moonte7933]

I have the exact kind of kmc chain on my mtb as the one shown at the beggining.

[@RJTheBikeGuy]

I like KMC chains, but didn't have one on hand.

[@maybedos]

KMC 410 is very cheap classic chain they last me like 3-6 months while a 410H can last me a solid 6 months but my all time favorite the 510H lasted me 2 years with heavy street bmx on concrete and park only got rid of it for a new lime green 410 for my 98' GT Performer. I wouldn't dare use a 410 or 410H for heavy bmx just for casual riding and for more park riding chain.

[@siahff2137]

Boiz

[@flawlessbutdysfunctional7787]

That fingernail lol

[@pedrofskymtb]

Thats only half the equation.. On a bmx bike, you add in consideration the chainstay length you prefer riding.

[@mcblits1638]

1:02, Tit teeth 😂😂😂

[@idonthaveaname3911]

that last part is annoying asf
