Hey i have a 15/16th size stem will this work?

[@bnick25352535]

Have a Cannondale sl4 has 1.5 head tube,not to many options in stems out there can i use a 11/8 somehow with a shim or to dangerous ived heard.

[@RJTheBikeGuy]

@@bnick25352535 You mean install a 1 1/8 fork? I wouldn't do it. Try to find an oversized fork. Check ebay.

[@hubertdevocion2449]

Hi sir, i really need your help. I have a 26er standard steel MTB and i wanted to replace the fork but i'm not sure if the fork that i'll replace will fit to the head tube. 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.

This video popped up in my KZbin feed today and came at the perfect time. I'm converting a 1" threaded to a 1 and 1/8 Threadless on a Schwinn klunker project with BMX bars. Great video! This conversion is much easier than I anticipated. Thanks again.

[@nuclearguitarfare4653]

Can't be anymore of a clunker than my royce union someone gave me for helping him move lol. But it has a euro bottom bracket so I rebuilt it. Replaced everything but the forks sofar. Turned out to be a pretty nice ride!

Hi my name is Jerry and I'm a lifelong bike enthusiast and I like your Channel but I need to ask just to see if I'm right or wrong when you put that dust ring around the stem before the spacers I'm thinking it should have been put on after the spacers please let me know if I'm wrong all right thank you!

[@stitchilalu]

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

[@smiff4748]

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.

[@schrodingerthecat]

Thanks for the video simply and perfectly explained, in my personal opinion I prefer a threadless fork because transform your bike completely and give a fresh look thanks again for the video and God bless you

[@DMGamer_PC]

Genuinely thought that because I was going from 1 1/8 threaded to 1 1/8 threadless I could use the same pieces... Didn't realize until I had everything ready that I had no way to tighten down the caps for the bearings x3 Thank you for the informational video; also realizing I need to hit up my local hardware store so I can jury rig some press/impact tools with some threaded rods and washers. Love to see homemade tools perform as well as custom ones!

[@tobins6800]

Hint and tip, a socket or 2 in the headtube that fits without binding inside can greatly assist in keeping the all-thread centered.

[@BlackJacketWasp]

Thanks for yet another definitive tutorial. As always, I am grateful that I don't have to do a trial-and-error.

[@TheAugiedoggie1]

AWSOME video! I have a Trek 970 I am converting to a Trekking bike and want to update to threadless head set. You just showed me how to do this. 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!!

[@chosenideahandle]

Can you use men's hairspray? Lol.

[@TekDristan]

Good information, as always. I tend to shy away from bikes with threaded headsets. Now I know how to change it if need be.

[@cristianomoreira8775]

Man congrats for this video, serious. For monts i seach for some solution for the problem of my old bike and on the Brazil don't find nothing too easy like this on your video! I'm glad for this channel exist and in this moment i will order my solution on the amazon lol! Hug from Brazil!

[@SFCRambo60]

You should put your cups in the freezer for a couple hours, they will almost fall in. Even just use a hair dryer to heat up the tube before installing will help.

[@KarlosEPM]

@SFCRambo60 is this really true? I'm renovating an old bike and this would help me tons.

[@kieranh2005]

Yup. Best if you do both. Shrink the cups and expand the steering head.

[@ericwarburton]

🤦‍♂️ Use a cup press and grease.

[@SonnetGomes]

Thank you so much. This is a very helpful video. If not for this video, I would have probably had the headset reversed. Glad I found this video. Can't thank you enough for how immensely for all you do and how helpful all your videos are. Thank you!

[@Grizzly907LA]

Seems, pretty straight forward. You and others got me inspired. Bought three frames today, and hopefully I can build at least one bike.

[@pahaahv]

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.

[@RJTheBikeGuy]

Threadless stem come in different lengths and angles to help adjust height. As well as the spacers.

[@DBDUFIEBTHDHDV]

MUST AMAZING AND NECESARY VIDEO EEEEEVEEEEER! I mean it. I have a threaded fork and I didn't think a conversion could be possible. I can make my bike better. Thank you so much!

[@neomanis]

Man, those tool innovations are on the fucking point! Smart, cheap, reliable! Kudos!

[@xenon9887]

If you trapped the washers touching the cup between two tightened bolts, it would ensure that the pressing surface is always straight. Then you only have to worry about the set of washers on the end you are tightening.

Great video. For my bike I didn't need a new fork as much as I wanted a better stem option (the Quill stem didn't work for me). I found a great adapter which has served me very well. 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.

I thought I broke my headset since the tube with thread broke. The first picture of the threaded fork cleared my vision😅 That good damn threaded tube was part of the fork. Now the Threadless conversation is justified🤤

[@joebananas4741]

Very good video. Clear and concise instructions. Love the homemade tools. That little grease gun is neat too. I'm actually thinking of junking my sprung fork for a rigid as it is so heavy. At least I now know the difference between threaded and threadless.

[@RJTheBikeGuy]

Going from a suspension fork to a rigid fork will likely lower the front end of your bike and change the geometry.

I've always used wd40. I like the alcohol idea (cleaner, and takes less time to disappear).

[@RJTheBikeGuy]

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.

[@creaturedanaaaaa]

What if I sawed off the threadless steerer tube, welded on a 1 inch threaded one and then just used an amazon threaded to threadless fork converter?

[@RJTheBikeGuy]

You are on your own with that! Keep in mind, when a fork fails, it generally fails catastrophically at the worst time.

Believe me iv seen this a few times

[@RJTheBikeGuy]

Keeping my threaded on my road bike. My steele fork is way to comfy of a ride to change out. I really couldn't care if it's heavy. Feels damn great on the road. Stiff on smooth flats/climbs and soft on bumpy terrain. Sometimes i have to look down at my front wheel because it feels like my tire is low but it never is lol..the damn thing feels like a shock absorber. I just use an adaptor so i can use a threadless stem on my threaded fork. Perfect.

[@FirstnameLastname-pe5ib]

If it feels like a flat it has loosened.

[@TboneTenEighties]

@@FirstnameLastname-pe5ib I know what you're saying but nothing is loose. I have been working on my bikes since a teen. The only thing i take it into a shop for is wheels truing. I have done it before but sooo much easier to get it done from my local.

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.

[@8day1989]

+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...

I've just bought a Trek 830 which i think 1995 model (internet search). It appears to have 1 inch headtube because a quill stem installed on its fork. I saw your video and your Trek 820 has a 1 1/8 inch headtube. I hope that my Trek 830 1995 has the same diameter. Thank you!

[@RJTheBikeGuy]

+dinhphuochoa kzbin.info/www/bejne/iYjFXmmng7mfptE

[@RJTheBikeGuy]

You could measure the diameter of the quill stem. the stem for a 1" fork will be about 7/8". The stem for a 1 1/8" will be about 1" in diameter.

[@Scubasig]

Nice video! very informative. You must have been thirsty because there were 3 cases of Diet Pepsi in the beginning and at the end only one was left! lol Looking to do this conversion for a Cannondale Headstock (1.5") to a threadless rigid fork (1-1/8"). Hoping the process is as strait forward as this. Thanks !

[@carlosamador8085]

RJ Awesome videos like always!!

[@kottelkannim4919]

DIY-ers should note that the handlebar is not oversized (1 1/8") but rather a 1" one. This reflects on the stem's dimensions, namely it has 1 1/8" steerer tube clamp and 1" handlebar clamp, like in the Bontrager one that RJ used.

[@RJTheBikeGuy]

The handlebar diameter only matters for what stem you use. And really doesn't matter for changing the headset.

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)?

I'm in the process of doing a threadless conversation and I just learned the hard way that sealed beating headsets won't fit if you were previously using cage bearings. I agonized about the specs too when choosing this headset

[@RJTheBikeGuy]

You use a sealed bearing headset if the specs match the head tube and steerer measurements. Were you trying to reuse the old cups?

[@myscreen2urs]

@@RJTheBikeGuy No. But after doing more research, it would seem that I bought a semi integrated headset when I should have gotten an external type. The one I bought had it so that the bearing presses into the headtube instead of above and below like the ones your demonstrating in your video.
