When I see that mustache, I know everything’s going to be ok
Jaaa!!
Calvin Jones is one of those people that makes the world a better place!
Oh a cliff hanger!! Will he fix it? The suspense is killing me!! :D
during covid im doing charity bike repairs for people in my area, ive watched the entire tech tuesday playlist and its been awesome help, keep up the great work park tool and ive definitely bought some park tools from watching this playlist!
Vikram Sreenivasan pretty damm cool man! ☝️👌
Can u help me then please
I bike to school and now my rear wheels are wobbly now i have to walk to school. I would have tried fixing it myself but i don't have and tools and i don't have any money to do so.
@@treasureaugustus7043 sounds like your rear wheel could be bent or the quick release axle could be loose, take it to a bike shop and explain your situation
Thanks!
Sir l am live in India
And you are my best Teacher
Thanks so much
*Sir i live in India
And you are my favourite Teacher
thank you soo much
Never thought I'd be on the edge of my seat in anticipation of the next installment...😮
I love Calvin’s humor!! Thank you so much for all you have taught me!!❤️😊
Here we go again…Calvin the legend!
Always informative, useful and entertaining. Thanks Calvin, and the Park Tool crew. 👍
Tech Tuesday videos are the highlight of my Tuesdays. Thanks for the video
This is the exact problem I have right now. I can't believe I'm genuinely excited to watch these videos, but it's true! This guy is awesome!
Calvin is ABSOLUTELY THE BEST MECHANIC ON TH-cam! PARK TOOL should give him a raise and PROMOTION!!
Calvin's wife: "Now where the heck is my toothbrush?!? 🤔"
My 1 year old "says" this, then she takes the greasy chain tooth brush and puts it in her mouth.
Love your expertise and humor!
Keep up the good work, folks. Thanks for sharing the knowledge.
The best videos. And the best person to learn from. Thank you!
The intro was golden
CB Outdoors yes it was
The cliffhanger at the end
hahah, I just did two broken axels today at the bike shop I work at, these were some great tips! Also I didn't even know it was possible to snap the front axel but hey someone did it! 😂😂 You guys are the best!
All of Park Tool videos, tutorials, etc. are very good, efficiency, both technical wise and practical wise.
Hahaha, so much to unpack here with this presentation. Really enjoyed this. Especially 3:08. Perfect.
Now this is real bike repair! No quick swapping, a proper fix with no waste.
Wheels manufacturing co. makes some great cromoly solid axles for older style cup and cone hubs that are less prone to snap or bend
I hate dull balls! 🤣 great Tech Tuesday Calvin and Park Tool👌
These pliers to lock on the threads are very handy. Had never seen those before.
youtube videos couldn't get any better than this.
At the cleaning process I was afraid you put the old cones back. After an axle broke everything goes in to the trash. Except the hub of course.
Very good video again btw.
Is the cones are damaged probably the cups are also broken. Redo the wheel with a shimano hub and that solves the issue
3:08 such confident sound of the mechanic master putting on gloves can tell, there's no bicycle problems he cannot fix.
Calvin is like the lab guy from any CSI movie who is the only person that cannot be left out while solving a case.
i took me some time to figure out how to fix my hub but after you get the hang
of it is actually pretty easy
Excellent
Oddly satisfying. Thanks for posting......
0:41 bingo‼️ that’s why I’m here…I knew it wasn’t the rim…the whole setup was new an alternate pair for “mountain biking” on my hybrid with cyclocross tire…now I need to loo up some parts
I'm sure it will be better than new after Calvin is done.
My compliments to the rider for riding that bike hard.
ne kadar da anlamasam ne dediğini .... ayrıntılı göstermen aynı dili konuşuyormuşum gibi öğretiyor .... çok teşekkürler ustam .... 🇹🇷
Aww I wanted to see it completed.
GENIUS
Hello Bonjour , C'est formidable , Merci au-revoir à bientôt , Thank you 😀✌
I appreciate your videos and fully support your products. I have used many Park Tools at home and in the shop (among others) and have always found every single Park Tool to be spot on, except the air chuck on my INF-1. That being said, I would have liked to see this done as one video. I know content is difficult to create, but the information would be far more useful as one video. Cup and cones are a pain for the inexperienced that may be using the video as an informational too.
Super!
I just had to fix this last week on my 2019 Giant Rincon (entry model freewheel and rim brakes) 10 months use about 4600 miles of use mostly sealed roads & dirt roads...... where I am I can not get new cones and the bb's looked ok so they are all back in until I can go get some new bits delivered.. (I got a solid axle in for now)... the same problem occurred twice with my last bike a GT Aggressor from about 2014. .....with the Giant I only noticed a slight wheel wobble .....oh and the bottom bracket has a little play in it now oh well.... ,
1:42 A quick release! 😂
The cassette hub was the best innovation ever. I used to bend and break axles every few years. As they added more cogs to the freewheel this got worse and worse.
you are weak, i broke 1 full axle every 2000km or one a month
I was breaking so many axles i thought my bike was cursed
Oh man now have to wait til next week, ugh. 😂😂😂😂😎👍
Υou re on top !!
Calvin, if we had more guys like you, the world would be a much better place! (oops, someone already said this..)
Mannnn just left me hanging.
I hate cup and cone always snap and come loose I went to hope and never looked back nice video
All of Shimano's hubs are cup and cone. Do you hate all Shimano hubs?
I have a entry level hardtail and the hubs are the worst part. When you "compare" them to a DT180 EXP it's like the Zambian space program compared to NASA
LMAO I’m with you there
What’s so bad about them? I have an entry level hardtail and the hubs can be repaired easy
@@MrFitness94 it's not the repair but the thing as a whole, the rolling resistance, and the adjustment, reliability etc
Kazak Thranduil adjustment and reliability are synonymous with repairs bro, which like I said is easy. Fresh grease and a tighten and it works like a dream usually unless the races, cones and bearings are shot. As for rolling resistance, maybe it’s worse? But the laws of thermodynamics DO say that a louder hub is a resistive hub
Are you a racist?
He looks like a Fireman 🚒 no offence,I love these videos by the way
That tire!
My rear hub can relate this 😂😂😂
can you do a vid on how to take apart suspension with inset bolts such as a the rockshox revelation for a 29 bike
What's the best thing to use to get all the old dry sealent off the inside of my tyres?? I used elbow grease and about 1 hour must be a better way??
hopefully you dont add to many bearings like you did in tech tuesday 74 =P, thanks for the great animation guys, keep up the hard work stay safe!
I had this problem a few weeks ago...
That's crazy that they even make a disc hub with a spin on freewheel. I guess non bike people are impressed by disc brakes, but don't know the difference between Freewheel, vs cassette. I'd try to sell the customer a new wheel with a cassette. Explain that they'll keep breaking axles. Otherwise they'll try to hold the mechanic responsible when they break the next one.
Right.
Are there 9 spd freewheels out there ? I had no idea.
I wish I'd known that coulld'a used one with a BMX freewheel on my single speed instead of the Ssp cassette system hub.
@@GeekonaBike A 130 or 135mm hub with a 8 speed spaced Freewheel setup will break axles if You ride even the slightest bit aggressively. A cassette hub has the main bearings out near the ends of the axle on both sides. On a Freewheel hub, the right side of the axle sticks out almost 2 inches without any support.
@@jamesconroy7030 Yeah I'm kind of amazed he didn't mention this "length of unsupported axle" thing -- The breakage pattern is indicative of this limitation of freewheels. I'm sure Calvin knows this but probably wanted to keep his script focused under the assumption that we'll be working with the existing wheel here, but I think it bears mentioning.
@Maria Martins Looks like this is a 7 speed freewheels which is where I think freewheels typically topped out (8+ speeds is usually a cassette/freehub setup)
@@chrislukes9037 I looked on eBay, and they do have 9sp thread on freewheels. 7, 8, and 9 speed all have the same spacing, so it won't matter as far as breaking axles. But it's just another example of cheap bike manufacturers making it look nicer than it is, while cutting corners on what the customer doesn't understand.
For me, if the cones are shot, i replace systematically the ball bearing , they cost absolutely nothing and if by bad luck you put back one worn ball bearing it will simply destroy your hub.
Might as well do it while it's apart.
That tier tho damn
Dang that tire is worn out hard AF lmao.
They road the piss out of that back wheel 🚵🏻♂️
I think using a magnet to pull the bearings out is a bad idea. It may magnetise the bearings. It will cause them to attrack ground up metal and other crud before and after they are placed back in the hub.
Get a 30x or 40x jewelers magnifying glass and inspect your old ball bearings, if only out of curiosity. It's a whole new world of pits and gouges.
It’s Tuesday and we don’t have a follow up! Don’t leave us hanging, Calvin. Hope all is well.
Tech Tuesday comes out every other week!
Park Tool Ooooh, ok. That will just make the conclusion even more satisfying. Thank you!
@2:50 whats the tool to pick up ceramic bearing balls?
Good day... How to change the bearings of shimano saint front hubs with 20mm thru axle?
With Shimano parts, always start at si.shimano.com. Enter the part number in the search box (sounds like you have an HB-M820) and review the documents. "EV" is the exploded view and parts list. "DM" is the dealer (service) manual. And "UM" is the user manual.
I would hope you use grease I hate it dry
Its supposed to be a video about hub problems.. But lucky rider the hub is fine..
I didn't expect that..
With a mess like that I would replace the bearing balls no matter how shiny they are.
on free wheel hub it is normally, put full axle, not hollow,
I’m have ig a problem where the axle doesn’t tile straight. How do I fix it?
Is that a FR-1.3 freewheel removal tool? Used at the 1:35 mark of this vid.
Yes, the FR-1.3
Hey man, i am worried that there is a lateral play in the cassette of my bike. Is it normal or should i replace it?
heh calvin, have you ever replaced the cups in a hub? then replacing cones and bearings...ive looked but been unable to source them.
Only Campagnolo supplies cups for hubs, and on only some models.
im optng for total replacement for peace of mind sake
my front wheel nice and quiet
rear wheel has copious amounts of play (if i tighten more the wheel will lock)
issues first arised within the first year rebuilt it problem gone
2 years later and a bikeshop visit later they are reccomending i replace my rims(wheels strugled to hold true and spokes felt ilke spaghetti) wheel flex is also pretty annoyin so something stiffer is in the books
i ride an odd branded bike as in i cannot find the brand online
thick alloy tubing all round (i compared the thickness by going to a bikeshop and tap testing on the downtube with my fingernail listening to the pitch) so i want to get atleast a few more years out of this frame as either my personal bike or the bike ill loan to my friends if needed its flippen heavy though
You made that snapping noise with your glove got scared thought it was probbing time
What do I need to fit Micro spline in X Caliber 7 2021?
You will need something with 141mm "boost" spacing. Looks like some of the bigger hub manufacturers are making it. Its not super common so availability is going to be limited.
So what was causing the axle to snap? Misaligned wheel, Suspension hand-tail,rough handling, pits cones, weak components, axle, lack or wrong grease creating friction in hub?
incompatibility of components too to consider.. ..
My cassette sounds like it makes a ratcheting buzz when I put it under a heavy load, any ideas? It is a brand new bike
Just quick question, if my bike is old does it worth so much hustle money wise and time spend or will be easier replace the whole thing ?
Often older bikes are worth repairing yourself. But this is not a cut and dry topic, it depends on the quality and condition of the bike you have and the time and money it will take to repair as well as what you want to get out of it.
Thank god Shimano ditched cup and cone
I found a crack in my rear hub on my full suspension mountain bike, and two of the spokes were broken off the hub, I've always been very gentle with my bike, I never take it off road, or do any jumps and I avoid potholes, but I do like to ride it fast and take hard corners at fast speeds, similar to a crotch rocket bike race when they lean their bikes close to the ground, could that cause my hub to crack?
Without seeing it, it is hard to say. If the failure at the spoke holes in the flange it is likely too tight spoke tension.
Hi, on a vintage wheel hub (1970s Schwinn LeTour) how do you remove the dust cap.???
Some dust caps have a slot for a straight blade screw driver. Some use a hex fitting for a hex wrench. Some use two pin holes for a pin spanner like the SPA-2. And some are pressed in. Look close for one area the is open for a thin screwdriver. Pry it out.
@@parktool Yea, mine is pressed in - thanks for the response.
My hub breaks loose during heavy load. I dont see my chain slipping so it must be the wheel. Can you do a video of this?
This really does sound like a chain skipping issue. The chain skips so fast its almost impossible to see. We have been trying to get it on film and its hard to get footage slow enough to even see the blur of it skipping.
I want to replace my rear hub ,its a sunrigle ,what are you suggesting?
Marmaduke D DT Swiss, sram, anything compatible with your spokes and hoop
can you make a video on replacing the ball bearing with a sealed bearing on a hub
On hubs it is not possible to convert from cup and cone to cartridge bottom brackets.
can you replace the inner race ?
Typically not, the cup inside the hub is pressed and parts are not available even if you got it out.
shimano fh tx505 freehub cant seem to find a way to service and having a hard time finding a replacment have you any ideas thanks
Y31S98020 should be the freehub body you are looking for. Hope this helps!
So what do you do if you have pot holes in your cup like I do?
There is nothing you can do, practically. Cups are not available as a replacement part. A new hub is needed, or just ride it. Once there is a pot hole, it will only get bigger.
Can u solve the problem that chain skip when back pedaling for 3x.....crank set
1. Stop backpedaling. If you backpedal, your front chainring becomes the derailleur, especially if you ran the chain diagonally before, which you should also avoid.
2. Check your chainline.
But my previous bike is not like that whenever i back pedal it won't skip.but my new bike skips when back pedaling🤔
It might be a shorter Chainstay length, it might be a newer system (10- vs 7- or 8-speed), where the manufacturer wanted to enhance shift performance under normal conditions, aka pedaling forward, but just watch this Tech Tuesday video th-cam.com/video/iySpqZkld2k/w-d-xo.html, where Calvin jones answers exactly your problem, and his conclusion is the same as mine: stop backpedaling.
3:08 & 8:33 🤣
A seven day wait
irl the cost of labour would mean that the whole wheel is trashed
labour for what? replacing an axle? thats an extremely easy and non-time-consuming task. i charge $15 CAD (11 usd) to replace an axle with new bearings. ( not incl axle)
if the hub was damaged, depending on what price you could get a new hub for and what price you could get a new wheel for, the labour for relacing your old hoop to a new hub could be close to the cost of a brand new wheel.
@JogBird Not for a kid with no budget and loads of time on their hands.
I had a customer bring in a wheel because of a dodgy axle. He had dismantled it, axle, locknuts, cones, seals... even went so far as to punch the cups out of the hub shell!
Brings in just the wheel, no axle or cones or locknuts, with the cups sitting loose in the hubs and asks "Can you fix it?"
No branding on the hub, no model numbers, nothing. He seemed quite certain a good bike shop was able to take care of this, and wouldn't really take no for an answer.
I have cracking noises in my bike think it's from the rear hub it only present when I cykling and peddling I can feel the cracking thru pedals and up thru my saddle can't find any other places it would Come from. I've replaced bottobracket bearings. I'm close to throw my bike away
Creaks can possibly come from rear hubs but it is not common. A few things to check is that your quick release is tight, your pedals are tight, and the crank bolts are all tight. If you can feel it in the pedals it tends to be a crank or bottom bracket creak. The rear hubs do not cause enough movement when they have issues to feel it in the crank.
@@parktool thanks everything is tightened but I felt the freehub housing is little to lose and when move it by hand slowly I can feel the ball bearings. So I'm gonna change the body. It's not creaking it's more like snapping or small banging but thanks for your input
I wish you were my next door neighbor
Calvin...I assume you work only for Park Tool, right? So who's bikes are these that come to you needing service? Do you guys look for parts that need work or are these bikes from Park Tool employees?
And has anyone talked to this particular bike owner about replacing that tire???
😂😂
That axle is fine. Just a little JB Weld and you're good to go.
Disc brake on a cheesy, cheap screw-on hub? Cro-Moly axle at least needed (then it'll probably snap again!), much better with cassette hub.
Damn that tire looks worn
