Convert from Threaded To Threadless Forks - 1 1/8 to 1 1/8 inch

  • I show how to convert a bike from a threaded fork to threadless fork. I explain the limitations of the conversion. In this video I convert from a 1 1/8" threaded fork to a 1 1/8" threadless fork. 1-1/8" threaded forks are known as oversized and are usually found on mountain bikes. The conversion involves replacing the fork, headset and stem. I install RockShox forks on a Trek 820 mountain bike that didn't originally have a front suspension. It's a nice upgrade for a vintage bike.
    I have another video showing the conversion of a vintage road bike with a 1" threaded fork here: • Threaded To Threadless...

I bought a 26er fork and the upper tube measures 28.6, i just wan't to ask you sir if the fork that i bought will fit to my standard MTB. I wanted to do some upgrades of my bike and i hope you can help me sir ☺ thank you so much.

    Greetings from the UK. Thank you so much for this my friend. I have watched quite a few video's concerning changing to a threadless headset but they were in no way as good as your video. You explained everything so that even an old fart like me could understand how to do this task. Keep up the excellent work. Once again thank you.

    Absolutely love your videos. I hadnt seen this one before but I wanted to check your methods considering I am going to be putting some threadless forks on a few frames. I love that you dont use commercial tools. I use most of these methods myself. I don't have cups installed on the frames but loving that split metal tube for removing the cups, its just simple and brilliant. This kind of thing really allows bike building and maintenance to be accessible. Thank you, I really appreciate it

    i bought step down headset cups for three sizes, 1", 1 1/8, and 1 1/4. They're just the cups, and I used your ideas for the homemade press! The cups alone are around $30, and it makes it a lot easier to press in the headset. The park press is like over $100, so it's a great compromise between the two! Thanks RJ for another awesome video.

On a side note I started cycling in the mid 80's and learned to do my own maintenance on my 7 bikes (all Treks). Your grip trick using alcohol was cool. I used to use women's hair spray which also acted as a glue when dried holding the grip in place. I have subscribed to your video's which will help me build this bike. Thanks!!

    I wanted to build a different geometry fork for my old ‘cross bike and change to threadless at the same time. I had a really nice suntour xc pro headset with grease injection. Im a machinist so I bored out the threads in the top race concentric with the bearing seat itself, to 1” id , made a thin brass compression washer.to sit on top. It worked great and 15 years later the headset is still doing its job.

They come in 1 inch and 1 1/8 inch. A search for quill adapter will find it quickly, in case anyone wants a slightly cheaper option or doesn't need the whole fork changed out.

  • @pahaahv
    @pahaahv Před 4 lety +4

    Threaded stems have one very important advantage for me as opposed to threadless stems and that is adjustable height. I have a Scott MTB I picked up for 20 bucks and it would be perfect if I could raise the handlebars maybe 5 cm higher, but it's threadless stem is already as low as it can be and the fork tube is cut to the exact size in factory. Right now having done maintenance on older and newer bikes I'd say the stems and saddle attachments look better nowadays but were easier to work with way back when.

    Glad I found this video, I'm planning an upgrade on my touring bike from rigid to suspension forks. I have no idea what the current fork shaft measures. I did replace the steering head and handlebars a few years ago, installing a 1" shaft. There's some play around that shaft, so I'm thinking I may be lucky and have a 11/8" tube. Where should I measure it to be sure (preferably w/o removing that front fork)?

    SuperSayanFitness, I wouldn't call it a "low quality" suspension fork. It is a good fork, just not the latest and greatest. But most of the newest forks are set up for disc brakes and don't even have the mounts for cantilever/v-brakes.

      Pateu Vegetal try to buy one off a friend or find a good deal on craigslist, eBay or any other selling platform. Maybe a bike shop might have one to sell for cheap.

    I like what you are doing by helping others without the knowhow and I'm sure you have save a lot of people a lot of money, I do find on some of your tutorials you are making it more complicated then need be, I'd never use or recommend this method of putting bearing cups in, all you will do is over tighten and leave a nice cracking in the frame. Believe me iv seen this a few times

      The headset cups are pressed in. That is how it's done. I used a homemade tool, as the professional headset presses are expensive. www.amazon.com/exec/obidos/ASIN/B000R2JJLW/ref=nosim/youtube25-20

    on your homemade headset press, use a second nut on the bottom that way you only need one tool to tighten it down, might make it less of a headache to use.

    +RJ The Bike Guy Have you considered putting wooden cylinder with a hole in the middle of this device? It should provide fast and decent centering w/o damaging inner sides of tubes. Also, you can make that cylinder a bit smaller than needed and adjust its diameter with some tape/paper/whatever. I bet some carpenter can make it for a relatively low price.
    Oh... after a bit of thinking I realised that you won't be able to use it for the other cap... I guess in that case you can use another cylinder of a smaller size. But now it seems like it creates more trouble than it is supposed to solve...
