Dear Park Tools, please give Calvin Jones a seat on the board !! He’s a legend
That is what we called "THE VERY BASIC OF MOUNTAIN BIKE SERVICE WE MUST KNOW"
Thats the exact same bb axle i have,so my bike is world sport?cool
If the threads are that corroded, they need to be chased out. I keep an old pair of half-blunt BB taps for that purpose, which are good enough to scrape it all back to bare metal again, but no good for recutting threads past a basic standard, & you're not worried by dulling them when you rub them through FeO2., which is abrasive.
Great video. I'm not a fan of the music though - I'd rather just hear Calvin talking.
Did I miss where he didn’t clean out the rust?
I like old bikes. Especially from 80's, 90's and 2000's. Easy and cheap to fix. And often buy parts at flea markets.
Cic plm ..
And they still work just fine. Put a set of cruiser bars on an 80's mountain bike with some friction shifters and you've got a good time! (add some wide slick tyres and a wider seat to finish it off nicely)
I rehab older bikes mostly Schwinn's and I received an abandoned World Sport. During the tare down in the crank where about 150 dead lady bugs. Most every bike has bearings that where over tightened from the beginning. Properly adjusted Cone bearings can be smooth as glass.
More close-ups please, it's hard to see what is going on.
Mr. Calvin Jones can be considered the King of Bike Restoration. That bike is still great. Replace hubs, chain, crank, pedals, brakes. And a little bit of cleaning and repainting, that bike will look good as new.
I get what your saying but, “replace hubs, chain, crank, pedals, and brakes.” might as well buy a new bike lol unless you get “old” brakes
@@Eng586 with that old bike. You can still restore it and use it. It's kind of dangerous to ride with old parts. So customize that vintage bike to a new one. And enjoy the benefits.
Watching this, i was thinking about a Calvin Jones /RJ the bike guy crossover
@@Eng586 that's a broken mentality, everything should be used and parts for these bikes are so cheap and you can end up with a very high quality bike at the end. i got a free frame with rusted wheels, 180 for wheels, 48 for tires/tubes/tape, and a bit more for ebay parts and cables. ended up with a great light weight vintage fuji way better than a Walmart bike and much cheaper than a bike shop
@@cstrike105 dangerous to ride with old parts!!???? - i ride my 1985 peugeot everyday and my 2 1988 rockhoppers often - all original except seat and tires
Calvin: "This is why you need a steel bike"
All the rust that came out made me think "This is why you need an aluminium bike"
AlO2 is as bad as FeO2, worse, perhaps.
Hey as long as it's not 6061 alloy it's all good!
@@paddychamp6069 ummm whats wrong with 6061 alloy?
@@esguerrajuanmiguela.9552 Nothing wrong with the material itself, it's the welds and heat treatment process used that results in welds that are about 30% as strong as the tubing and have a finite life before cracking.
Components that are only machined and not welded like bars, stems, seatposts etc are fine but 7000 series alloy is a bit nicer if you can find and afford it.
Here's a simple guide to buying 6061: does it have welds? Don't buy it.
@@paddychamp6069 I’m a big, strong rider, and have broken several 6061 frames over the years….but none of them broke at the welds. But, I don’t think this is an “aluminum problem” since I have also broken several steel frames…as well as every weight bearing component you can think of!
Guess he didn't use WD-40 on the rusty bb because Park Tools doesn't make it :-P
Extremely well done and helpful. Where would we be without Calvin Jones?
When Ever I Work On A Bike Like This, I Always Try Hard To Save As Many Components As Possible. That's Where The Satisfaction Of Bicycle Repair/Restoration Comes From. Nice Video!
thought you would use some rust remover on the inside of the frame first, unless you think its ok?
I was thinking the same thing
They should spray some lanolin inside the frame
Wow crazy to see one of these being worked on. I had a Schwinn World Sport from 1987, the black and gold model in the catalog. A great bike in its time with a chrome-moly frame and aluminum components. By the mid 1990's the World Sport model was gone and Schwinn was focused on MTB style bikes, with only a handful of road bike models like this one.
Another one bites the rust...
PS: I liked the creative clamping of the HCW-4 tool.
anti-seize without gloves? you are a wild man
Is it that bad?
Chemist speaks. It’s no worse than any grease. Just grease with additives like molybdenum disulfide aka Moly Lube, a slippery solid.
@@freds4703 So i can just use my fingers to apply it, then wash my hands? I've been doing this with any kind of grease for years and i honestly didn't think abt twice until now lol
Calvin is the Park tool Yoda
My 81' Sports Tourer is mint. Just went over it last year. New bar tape, brake hoods, cables and rubber.
When i bougt New bike from bike market same size valve tire. But when i serviced the valve tire are Tall and Small. Why?
Literally EXACTLY what I was looking for! LoL love it! Tx!
Why not chase & face? Judging by the intact paint it does not appear to have ever been faced in its life; wouldn't that improve things, especially since the race did not show normal expected wear?
That chain is bugging me...
Bonjour Calvin , Super bike restore , Thank you 👍😀
For all the so-called "high tech" saddle science we've been bombarded with all these years, those Avocet Racing saddles are still one of the most comfortable bike seats ever made, even on a full race mount.
Chasing the treads on a bottom bracket is the most rewarding feeling while working on a bike. I'm surprised you didn't show that tool off.
Chasing and facing BBs is very cool, good tools for it aren't cheap though!
I love your videos! I made wall art with my old chain that rusted out. :D
Park Tool University….! ❤❤
Holy crap that's a lot of anti-seize on those threads. It's almost like these guys sell it by the tube or something.
THIS IS why... You want a steel bike 😛
this guy is way to funny.
glad you are doing this series!
What is the part # of the crank remover and the spanner?
I love my 1983 world sport
Why are bicycle tools so expensive
Good as always. Thanks Calvin.
if i have cotter pin crank axle how do i meassure to find the equivalent in sealed cartridge
If you are switching to a sealed cartridge, you will need to switch to a new crank. The new crank will tell you what spindle length it is designed around.
Dry grease, for the summer. ;)
Hey now Calvin, that World Sport reminds me of repairs I saw in Santa Barbara in the late 1970s. I was Service Manager for two shops, Hendrickson’s, and Open Air. Among other duties, I wrote estimates for incoming repairs. That stiff, corroded World Sport chain, and the BB, is good evidence someone rode in deep water. In Santa Barbara it was usually the Pacific Ocean. Salt water could ruin a lightweight steel frame if left untreated. We would spray a good amount of LPS3 or similar sticky lubricant inside the accessible frame tubes when servicing BBs of likely Pacific submersion experiments.
I just hope that - like these square taper ones are now - the Octalink compatible BBs and cranks will still be available in 20-25 years...
Somehow in my country Octalink BBs and cranks are extremely rare. Seems like it's either the traditional square taper, or the newfangled Hollowtech. I've quite probably never seen an octalink IRL.
An adjustable wrench to install BB extractor? Tool of amateurs. Only to be used as a last resort if the proper tool (open end wrench) is not available. Using a pedal wrench for leverage to take the crank off is the perfect way to ruin your pedal wrench. Proper tool here would be a socket and a long breaker bar if more leverage is necessary.
The purpose of many videos here is to show how people can do this at home. They are not professionals, and we try to show how they can still have success.
@@parktool Your videos are a good chance to teach the use of proper tools. I would suspect that anyone with a crank extractor would have open end wrenches and/or a socket set.
This is not for DIYers
RJ the Bike Guy did it.
Jesus Christ I just fixed my old bike 2 hours ago with the same exact problem. And this video poped up....
whenever I work on an old bike, mtotorbike or car I always have release oil/penetrating oil at hand and would have soaked all those parts for at least half an hour before starting any work. I just took the floor board (to repair it) of a 2007 Suzuki step twist and go scooter by first putting oil down the 4 screws a week ago then 2 daily squirts of release oil.. I was able to remove a screw with a mangled head a mechanic could not get out... after my treatment with just pliers......good video but you need to shoe close ups if you want newbies to really get what is going on....keep them coming guys !
Considering how it’s currently harder for some to get a new bike than most can obtain a PS5: THANK YOU FOR SHARING!
Like 👍🤝🌹
Good job....I want to be bike mechanic, thank you for your videos
excelent as always! Please could you put videos in Spanish? greetings from Patagonia Argentina

Love it
I always like to give a good serving of WD40 or similar before dismantle, and grease or similar on threads and tools, yes it can get messy, but it helps a lot with not rounding or destroying tools, or interfaces. I have cut one too many bbs out to not tell you this haha
Hi can you help trying to remove pedals to change wont buge tyres a bit of heat that wont budge
Thanks
That should read tried
Pedals can be quite tight. Have you given this video a good watch? ua-cam.com/video/LFbSBG7jMzY/v-deo.html&t
@@parktool thanks for reply need a pedal wrench 😎
I have an 86 world sport! Siiiick
Restoring/rescuing an old bike. What a great idea for a series.
I went to my fav local bike shop and had them rebuild a 1990's trek 950 (drool). There was a moment when the tech stopped me and said JUST SO YOU KNOW YOU COULD BUY A NEW BIKE FOR WHAT YOU'RE PUTTING INTO THIS.
Yes. Yes I knew that.
I love seeing old bikes, if they're in good condition they can be saved. Most people don't want to work on anything older (because of parts, money, labor time) I get the same thing with my 98 CRV, but again some people love a certain style!
When the chain gets brown, Calvin's gonna frown.
Cant wait for next Tuesday 🤩
Put the two sides in loosely, not at full torque (WITH ASC/GREASE ON THE INSIDE OF THE LH ADAPTER AS WELL! otherwise, it will creak!), then torque them both incrementally, in 2 or 3 steps. If either of the threads are a bit crooked, then the BB will pull itself into alignment with them better that way.
These videos are just the best. Thanks for these!
Can i ask your opinion on the metric system, I'm in Australia, so moot point for me, but with most bikes being metric, is it an issue for Park to deal with Domestically....
We think the metric system is great! The Imperial system of inches, ounces, pounds, is not going away. The bike is a mix of each. The ball bearings in your bike will be 1/8", 3/16", and 1/4". Steering columns are 28.8mm, because they are 1-1/8", and were designed that way. For the foreseeable future, you need to be bilingual, knowing both your inches and your metric.
i do this service several times a week for customers, but i still find it ridiculously satisfying to watch someone else fix it. I'm disappointed this bottom bracket was prepped and pre-loosened. they never come out this easy.
That bottom bracket was not faked or preloosened. We are not afraid of having and showing problems, just like the stem on this bike. I suspect the bike saw mostly porch time, not road time. Much more to go here on the Schwinn, and if there are issues, we will show them.
Awesome...thanks!
✌️✌️✌️😶👍👍
Интересно
I really want to see a video some day of Calvin *riding* a bike.
How is this one?
ua-cam.com/video/HhTPQ0nVWzY/v-deo.html
@@parktool Hah! There he is on a bike! Who knew.
If anybody out there is doing a refurbish on a bike like this, a wheel upgrade will make a world of difference(no pun intended). You can get a cheap wheelset for $150 and it will ride like a new bike.
god👍👌
Hey Calvin i have been a cycle mechanic for 20+ years and a laughed when you got that BB out without a struggle or swearing! I guarantee you had that frame pre prepped for easy disassembly and that is why we have professionals to do the hard work and charge accordingly while you cheat and make it look easy. Thanks Calvin
Believe me, we would show the struggle if there had been one. It surprised me as well. It makes for better video on these old bikes when there are problems. The stem was stuck, and if the bottom bracket was stuck, it would have been captured.
Type 2 spindle. Need special puller. Don't try this at home, but a cold chisel between the crank arm and the flat surface of the cups also works! Use hammer judiciously. Of course none of this should be reused but have had crank arms wedge off apparently no worse for wear. BB is toast anyway so no matter.
I have the same vintage Avocet saddle, it's amazing, very comfy!
sorry calvin but your wrong at the end: Preload at the right side without the left installed... think about when the threads are NOT perfectly aligned, you will never get the lift side installed...
The driveside is torqued to spec first then the non drive side is installed and torqued. If you experience issues installing the non drive side, remove the bottom bracket and use the BTS-1 to check and repair the alignment of the threading and threads. But, always tighten the driveside first on this type of bottom bracket.
@Haste Gedaxht - Thank you for keeping me in business.
To the dump would be the best idea with that bike
