Protect this man at all costs
Lol
Couldn't agree more
From what does he need protection from??😅
Calvin is astonishingly good at what he does. Perfect, straight to the point. He explains things so perfectly. You can tell he’s been doing this for most his life and his passion is inspiring. Park Tool, I hope you realize that many of us buy your products, not just because of your quality, but also because of this man. Thank you Calvin.
Who the hell gives Calvin Jones a thumbs down? I mean, it's CALVIN JONES !!!
Agree!! Glad to know I'm not the only one who feels that. WTF?!?
Probably the new handle bars...
The Chicago Schwinn fanatics and everyone who thinks quill stems and threaded headsets magically come loose and cannot be kept tight. And the ones who think 1" steerers can't possibly be strong enough. And the ones who think quill stems are old tech that should be forgotten and never spoken of.
this guy has mustache, I trust him
That guy in a mustache is the director of education of Park Tool, he's like PhD in Bicycle Engineering
@@outerspacekaloy did you swallow?
@@Snagmaster30lb nah, I spit, perhaps
Wtf did I just learn??
@@johnboygunsling666 nothing...
"and that is the end of the video" HAHAHAHAHA
Even the crew laughed at the impromptu joke
So relatable, had this issue a couple of times myself.
you don't have a quill and you don't care about converting to threadless... you're just here for Calvin Jones!
Amen lol
You are right. You totally got me
Why would someone cultivate on their upper lip what grows wild on their rear end?
You got me 😂
At this point I don't even feel like you exposed me anymore.
Love the idea of using stem spacers, purely for the looks. Brilliant!!
Calvin is simply the best.
Reclycling old bikes.
In Tuscany - Italy every sunday afternoon
a cycling club is riding recycled bikes, made in the Sixties/Seventies.
Now that sounds like fun! One day...ROAD TRIP to Tuscany.
you learn and its entertaining, love these vids.
Ha, I thought it was just me that ran into these types of issues. You guys always make it look so easy in these videos.
Calvin's mustache deserves it's own channel
Great delivery today ! Well timed and nice to see a more realistic real world example
extremely unique tutorial showing the common issues you may encounter. usually the tap on the bolt frees up quill stems but its cool to see a pro deal with the worst issues consumers may encounter
This is fantastic! I've got one of these converters to put drop bars onto an old steel MTB frame so I've just been watching a bunch of videos on how to use them. Yours is the only video that showed you using spacers like that, which is what I want to do. Thank you so much!
Thanks Calvin. Your most emotional tutorial. You're the best.
About to do the same to an old frame, adding the spacers to hide the adapter taper and give a cleaner look is a great tip
😆😆😆that's the end of the video
Excellent !
As soon as you struggled with the stem i thought "hmmm... pretty sure that was not in the script" but you kept going until you couldn't. Hilarious.
Someone should have checked before starting it wasn't frozen inside ! Where isTruman when you need him lol ?
To be fair, the bike didn't look rusty at all bit this stem had to be inserted in... 1983 or so, lol.
Well done. Thank you for sharing with us, it's totally cool.
I could so much relate to him there. I had to abandon a bike frame for this exact issue.....
Hello Park Tool! Interesting but a little confusing… The final setup is a mix of both systems so don’t go wrong with the screws. Indeed, it can be very dangerous because it’s your steering, so be careful. Otherwise, very good content as always and it’s simple, you’re my master in the bicycle repair world even if I’m French ! I love learning new skills with all your professional tips and advices and in happiness. So, thanks you very much for sharing your passion with such a high quality expertise. It’s extraordinary! Finally, I also love the good quality and design of your tools, so good job, really!
Such a funny bloke! Great work Calvin
Carnales, son la meritita reata, realmente esto es la universidad de la bici, muchas felicitamientacionatividalidades. Thanks a lot for that awesome teaching, buddies!
That is the video i was looking for from experts...thanks ParkTool team..
aye, way to see it through, bud!
A great video as usual Calvin. Informative and entertaining👍
I just did this a few weeks ago to a 1990's Bianchi Campione D'Italia to keep it authentic looking with its original celeste fork. Works well!! I'm glad you kept the video real by showing the difficulty of removing the old fork, many people will have that problem.
I would watch Calvin work on anything on a bike... or anywhere else! I always learn something and enjoy it :)
Every time I get in a pinch this account gets me out of it- and provides a greater awareness!! Park tools 🛠 4 life
Nice video, good explain 👌🏼
Hello bonjour Calvin , magnifique ! Thank you 👍😊✌
"before we can get an adaptor or anything in"....I have to go and hit the gym! Lol, that initial effort/fail was hilarious! But I am in complete agreement with everyone else Calvin Jones is a BADASS!
This is what I waiting for..❤️
This is precisely what I’ll be doing to my ‘94 Kona Cindercone (bought from eBay 3yrs ago), the flat 130mm stem will be replaced by a 90mm aheadset MTB riser stem onto a 1 1/8” quill adaptor. I bought the DC-1 caliper because I needed to understand the inside & outside diameters of stem and steerer. 👍
You had me when you said this is the end of the video. But you really got me laughing so hard when tossed the old handle bar.lol this is why i always come back to watch your videos. Not only are you knowledgeable but you are funny as well.😎😁😂👍
These old bars fetch premium prices on auction sites, though.
Great video!
Would love to work with guy so much knowledge and wisdom ✌👌👍
Been looking at a Soma Rush and researching the quill conversion as the Soma fork is 1inch. The hide the converter with stack washers is a good tip!
literally just been doing this the last days .. had the corrosion thing binding the bottom piece of the quill .. ended up having to tap it from the bottom after removing wheel and brake .. good video
I’ve done this conversion recently. Super easy and really widens your options for stem lengths and angles. I’d like to see a square taper bb to Shimano Hollowtech 2 conversion soon.
That's not a conversion. That's just a replacement set of cranks and BB.
@@SiopaoSauc3 Replacement would be if I just swapped out the old square taper to a new square taper. In this case, given Hollowtech 2 is mechanically different with how the crank arms interface with the BB and frame. You’d also be surprised to know lots of new riders and amateur wrenchers don’t know about HT2 and it’s benefits. I didn’t and happy I made the switch.
You just replace your square taper bb with the correct bb for your hollowtech crankset. It really is just replacing one bb with another and replacing one crankset with another. It's a very very very common upgrade.
@@dougse-bike9770 Like I said, that’s not common knowledge among new cyclists. In fact my LBS didn’t even propose HT2 when I asked about going from 3x7 to 1x10. Those of you wrenching on bikes for a while know about it, and now I do too but it would be great if Park Tool did a video about “easy upgrades.” RJ the Bike Guy can’t be the only source.
By far the funniest park tool commercial ive seen this guy in. What was going on in his world that day?
Lols, this got unexpectedly funny. So good!!
This was informative and also funny :)))
Exactly what I'm gonna do in a few days.
Only Park Tool could turn a two munute job into a ten minute bore!!
Calvin Jones,i love you 🤣!
I can't stop laughing!
Wow that’s really cool that old bike is now cool
five stars to Calvin.
Looking at doing this to my one Bridgestone. Have the adapter coming. Know the handlebars I’m getting. Just haven’t figured out the stem leangth and angle yet.
Addendum Method B (for when the stem quill is REALLY stuck): remove stem bolt, plug stem bolt-head hole with a cut-down cork or rubber plug. Turn bike upside down in the stand (or on the floor, in the corner). Put some newspaper or cardboard under the head tube. Pour as much Coca-Cola (original, not Diet, nor any of the fancy recent deviants) as will fill the steerer tube, maybe to an inch below the bottom of the fork crown. Leave it overnight, or as long as you can spare. Gently pour it out (save it if you want to use it again) by rotating the bike. Put a trash nutted wheel in the forks. Apply force as per Calvin: with luck, the Phosphoric Acid in the Coke will have eaten away at the corrosion bond between stem and steerer enough for you to break it as per Calvin. You can use vinegar (as strong as possible: 8% pickling vinegar is great) as the Acetic Acid does pretty much the same thing, except your workshop will smell like fish and chips for days. Cheers, from Mark In Oz.
Just bought a part tool handlebar holder
Lucky! I'm trying to get one but they've been out of stock for months.
Some people use adapters for conversion just like in this video. Others swap the bearings from caged to sealed. What are the pros and cons of either process? How do I choose?
I have a vintage bike (1" or 22.2mm diameter) and would like to swap to a modern ahead stem. How do I know which upgrade process is right for me?
Many thanks in advance.
How about an out takes video. Calvin and Truman look like they have a lot of fun
Looks good. But with the rust you found, I would think the headset bearings would need some attention. That would have been easiest to check while the stem was out.
What a stud
Nice. I still haven't come arkund to the conversion. I keep paying a king's ransom for 1" threaded carbon forks or doing back alley deals for them.
Thanks sir jim croce
I've got this same year of Schwinn World Sport in my garage.
did you know that the schwinn "world" series from the 70s was actually made by Panasonic? don't know how late back it goes but its pretty interesting!
Panasonic; with a plug and a cord 110 Volt/ 230 volt, an electric bike ?
@@b4ptist
Can you apply carbon gripper compound to the outside of the wedge to prevent sticking or corrosion later?
An anti seize compound or "liquid torque" should do the trick and is probably cheaper than anything associated with precious "carbon".
here in Recife Brazil this happens every day 😂😂😂
Reality funny and interesting good job
I love to see the trekking bars. I’ve changed to them 6 months ago and put on over 1000 Kms. I ride all terrain so trekking bars give me great control upright and still able to go down aero for pavement riding.
Why aren’t these more popular in the states?
Pulling up those bars I was so not looking forward to the moment it released and Calvin smacked himself in the chin. Me and chainsets have history.
I missed the tech Tuesday
on my bike the quill stem was rusted on very badly and i just sprayed some wd40 on there and hit the handlebars with a rubber mallet with some force and it came off so easily 👍
We see you Calvin
The best Mustache ive seen in ages im Jealous
I LIKE THIS GUY.....HE IS COOL 😎👍🤣
hi thank you for sharing question the Stem Column Adaptor 1 inch Threaded Fork to 1-1/8 Threadless Stem do they come in different length or one standard size? thanks.
I did this exact conversion but I'm not happy with the results. I'd like to get rid of the old threaded locking nuts. The hex head bulky double nuts don't match the modern look. Why don't just relay on the threadless locking system? Would like some input on this please and thank you.
A threadless system means replacing the old threaded fork with one that is threadless. Check out Innicycle for a really nice threaded-to-threadless conversion set. It’s pricey and involves replacing the old headset cups too, but it’s a very slick piece of engineering and the best way to keep your threaded fork (big for vintage restomods/aesthetics).
Хорошо
Had this kind of setupon my cheap BMX 10 years back
Calvin I have an specialized ariel with Quill stem and axel thru fork but want to change it for a QR fork do i also need to change the quill system ?
It is true that the threadless stems and the quill stems do not directly interchange. Double check the fork and wheel on that model. It seems an unlikely combination. Send us a pic if you like through our tech email at www.parktool.com.
Nice one Calvin...Reality happens. Nice to see it happens to Bike Gods too. Lol
ooo 169 nice
What size is the ball bearing shimano r540
Hey calvin! I measured the outer diameter of my quill stem and it is 21.9 mm.
Will an adapter of 22.2 do the job?
I'm pretty confused about sizes!!
Bike can be confusing with so many standards. Is this an older French bike? There is old French 22.0mm standard. It is also simply a poorly made stem in the 22.2mm standard. If it is not an old French bike, it is likely the 22.2mm standard.
When you do this conversion, can you use a different top cap? My sons bike has the quill type and he wants a custom cap like mine.
You could probably make it happen if you drilled the cap for the adaptors bolt. The bolt on the adaptor is very similar/ the same as the quill stems bolt. You could remove the existing cap and size a custom one. Long story short the custom cap will not be a direct fit.
100 + nice
one of the better ones! except those ugly handlebars
Hehe i never see this guy make a joke hehe 😜 nice one hehe
Go to take the quill stem out
OH YOU DONT WANNA COME OFF THE EASY WAY DO YOU NOW YOU LITTLE QUILL STEM,,,,
People , things like this are a classic day in the life of fixing bikes
Can I used 22.2 stem adapter size to a 25.4 inner size of the fork, because I am not sure to the exact size of my MTB fork? That is why I am planning to buy 22.2 stem adapter
What size are the spacers 1 1/8 ?
I wish your products are available in my country
Where are you located? There may be a nearby distributor who can help.
@@parktool Philippines
Dan's Bikes are our distributor in the Philippines: www.dans.ph
@@parktool thanks for the info guys i haved check the website but they have only limited number of product from your company
At least mention that the headset needs to be serviced. I've never not been able to get old stems out, same with seat posts. Penetrating oil and patience are your friends.
I had one seized I used refrigeration gas to chill the stem while heating the forks and pulling it apart with 4000lbs (forklift ) it lost
now that's some brute force
I need your help sir how to get
Do you have to change over to a threadless headset? Can you change over to a threadless headset?
Going from a threaded to threadless headsets first requires both a THREADLESS fork and a threadless headset.
Can I convert from 1 1/8 threaded to 1 1/8 threadless? Go from thread to threadless as long as everything is the same size? Unable to find clear answer anywhere about this. Replace headset to threadless one? Replace handlebar stem and handlebars if have to?
Yes, it can be done. New fork of course, and stem. Get new bars if you want to switch to a different width, style, etc.
does someone know when safety brakes were introduced for bikes and for what purpose
They were introduced in the early/mid 70's, and the purpose was to make things safer but, like many poorly-understood safety designs, actually made things less safe (people relied on being able to brake from the top of the bars but, unless the brakes were set up very carefully, and kept very well adjusted, people found that the safety levers bottomed out on the bars long before enough braking force was being applied).
@@type17 thanks
@@type17 Yes, hence their second nickname: Suicide Levers
I have a bike that is both a quill stem, and has a 1 1/8th diamiter headtube (assuming i read the measure right.)
Would that mean I could just go straight to 'buy a modern fork and headset'?
You sure can. You'll need a new stem as well.
@@parktool Naturally, I just wanted to make sure it wasn't more complicated than 'get new stem, fork, and install.'
Kindof annoyed really. If the head tube is the proper diamiter for threadless, why is huffy still making quill?
Ouch you just throw it hehe
If it's 1 1/8" threaded forks, can you put a threadless stem on the outside?
Not recommended. The stem would be clamping on the fork where it is threaded, which is a series of cuts in the steel. It would be weaker in this area as you stress the fork side to side by riding. Failure will eventually occur.
@@parktool Thanks so much for responding and the really helpful advice. I'll keep an eye out for threadless forks or get a quill adapter instead. Thanks again!
Can you put a threadless fork on a frame with a threaded fork? Want to turn my ridgid bike in to a hardtail
In most situations you can. Something to note is that a suspension fork often changes the geometry of the bike and can exert forces on the frame that it was not designed for. This can lead to frame failure.
Love it when I see Calvin get stucked haha
This was totally unexpected. My mind blown . But what if you change the forks ? Can you get threadless forks . ?
For the 1-1/8" standard, it is easy to find threadless forks. This was a 1" fork column, and threadless forks are not easily available.
@@parktool thankyou that is knowledge that will stay . This was very promoting and when I felt discouraged over an older style bike this VIDEO made it worth they buy of a vintage bike . (Bike is in good condition I just wanted shorter stem)
Bring back the CR-2 please!
I hate threaded and quills. It's always a pain to remove, you need a lot of sh*t like oil and special tools. The guy who invented threadless stems was a gift sent from heaven
Let me know the next time you want to do a threadless conversion. I can send you an innicycle threadless conversion headset to install.
I thought park tool had every tool but not a Shock pump
🎉
Say what surgery,? Is that the last option hehe i hope it will not end up flat line hehe
