The cliffhanger at the end

[@benblaser2593]

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!

[@kennymoey49]

All of Park Tool videos, tutorials, etc. are very good, efficiency, both technical wise and practical wise.

Love your expertise and humor!

[@scottpink2013]

The best videos. And the best person to learn from. Thank you!

[@attilamelcher7297]

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.

[@pedro3115]

Is the cones are damaged probably the cups are also broken. Redo the wheel with a shimano hub and that solves the issue

[@ScrubsIsee]

Keep up the good work, folks. Thanks for sharing the knowledge.

[@paullouthan4390]

Hahaha, so much to unpack here with this presentation. Really enjoyed this. Especially 3:08. Perfect.

[@mariamartins367]

These pliers to lock on the threads are very handy. Had never seen those before.

[@ak1920]

Wheels manufacturing co. makes some great cromoly solid axles for older style cup and cone hubs that are less prone to snap or bend

[@frankwong1983]

3:08 such confident sound of the mechanic master putting on gloves can tell, there's no bicycle problems he cannot fix.

[@cristibadeaneo1992]

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

[@keithm8715]

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.

[@davidburgess741]

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.

[@makantahi3731]

you are weak, i broke 1 full axle every 2000km or one a month

[@mindaugasrostkauskas9670]

I was breaking so many axles i thought my bike was cursed

[@Montblanc1986]

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

[@lfsiuvagacwoi]

LMAO I’m with you there

[@MrFitness94]

What’s so bad about them? I have an entry level hardtail and the hubs can be repaired easy

[@Montblanc1986]

@@MrFitness94 it's not the repair but the thing as a whole, the rolling resistance, and the adjustment, reliability etc

[@MrFitness94]

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

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.... ,

[@jptrainor]

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.

[@iolaos_Lute]

Υou re on top !!

[@jamesconroy7030]

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.

[@mariamartins367]

Right. Are there 9 spd freewheels out there ? I had no idea.

[@GeekonaBike]

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.

[@jamesconroy7030]

@@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.

[@chrislukes9037]

@@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)

[@jamesconroy7030]

@@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.

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!

[@Twongo]

That tire!

[@betruly7894]

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.

[@PnlBtr]

Might as well do it while it's apart.

[@jeffhayes2288]

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.

[@IntrepidPT]

I had this problem a few weeks ago...

[@MrRustaf]

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 ?

[@parktool]

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.

[@Samkoutloud]

Its supposed to be a video about hub problems.. But lucky rider the hub is fine.. I didn't expect that..

[@rossmann611]

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.

Good day... How to change the bearings of shimano saint front hubs with 20mm thru axle?

[@mattgies]

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.

[@ernest1576]

You made that snapping noise with your glove got scared thought it was probbing time

[@squidelleotious6362]

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?

[@parktool]

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.

[@bikingwithryan5968]

I’m have ig a problem where the axle doesn’t tile straight. How do I fix it?

[@donavinnezar]

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

[@averagerider92]

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?

[@parktool]

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.

[@Bogdan-le3bk]

That tier tho damn

[@dieseldavedick]

[@marblox9300]

Hi, on a vintage wheel hub (1970s Schwinn LeTour) how do you remove the dust cap.???

[@parktool]

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.

[@marblox9300]

@@parktool Yea, mine is pressed in - thanks for the response.

[@paulb9769]

Thank god Shimano ditched cup and cone

[@jhunemagrata1341]

can you make a video on replacing the ball bearing with a sealed bearing on a hub

[@parktool]

On hubs it is not possible to convert from cup and cone to cartridge bottom brackets.

[@MaQuGo119]

What do I need to fit Micro spline in X Caliber 7 2021?

[@parktool]

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.

[@Metal-Possum]

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.

[@ernest1576]

I would hope you use grease I hate it dry

[@linlinlixin2637]

So what do you do if you have pot holes in your cup like I do?

[@parktool]

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.

[@JogBird]

irl the cost of labour would mean that the whole wheel is trashed

[@bmxscape]

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)

[@bmxscape]

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.

[@CyclingSteve]

@JogBird Not for a kid with no budget and loads of time on their hands.

[@TheCaptainbarbwire]

Can u solve the problem that chain skip when back pedaling for 3x.....crank set

[@benjaminfriederichs3189]

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.

[@TheCaptainbarbwire]

But my previous bike is not like that whenever i back pedal it won't skip.but my new bike skips when back pedaling🤔

[@benjaminfriederichs3189]

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 kzbin.info/www/bejne/n6q2oaSQoNGXaM0, where Calvin jones answers exactly your problem, and his conclusion is the same as mine: stop backpedaling.

[@woof3598]

can you replace the inner race ?

[@parktool]

Typically not, the cup inside the hub is pressed and parts are not available even if you got it out.

[@NOne72]

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

[@parktool]

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.

[@NOne72]

@@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

[@Exgrmbl]

could be rear derailleur adjustment that is off or the lock ring on the cassette is not tightened properly.

[@ollieb9875]

Perhaps the chain is rubbing on the front derailleur cage if it has one.

As stated above you may want to take it back and see what the shop says. Another common rattle is spoke protectors. If not setup right they can rattle quite a lot.
