"College kid is a tool" truer words haven't been spoken lol

I caught that too hahahahahah

[@garonburwell9008]

best joke i heard all week

[@biohayzer]

Beat me to it…word for word!!!!😂👍🏻

[@ElliotFlowers]

he also said nuts. and screw. and nipple. yawn. oh and bottom bracket. heavy yawn.

[@B_COOPER]

Hmm, I see what you did there… true… spoke… the context of it being the exact part that true spokes are connecting to…

[@Markez0817]

Park tool, please make sure this guy is happy. You all are lucky to have him.

[@B_COOPER]

I have a hard time believing Calvin could ever be unhappy working for Park Tool

[@jimbrittain402]

Well done on that hub situation. Don't open it if you can't fix what might happen if you do!

[@bmxscape]

@@zygmuntthecacaokakistocrat6589 ...hence why they cleaned and lubricated it. did you hear what he said? it doesnt need grease

[@mattgies]

Correction: Mr. Jones was talking about disassembling a freewheel, not a hub.

[@mikecarter6758]

Always tune in to watch Calvin. He’s a master!

[@TheLurker]

The best part was Calvin laughing at the second sprocket being threaded as well. How many moments like that have we all had....

[@bobwilson7464]

I think my enjoyment of this series stems from fact that I have made e hobby out of working on old beat up bikes like these, and watching the video version of the process of trying to solve all the problems you bump into is really funny.

[@stefannewels1823]

Doing this stuff for over 25 years now and still have to watch it when Calvin is wrenching 😎

[@Likelybiking]

Definitely down for a video of a freewheel service

[@twowheels222]

"the more chrome the better" 👍 Got to have priorities straight.

[@harukishiga6066]

Idk why but whenever i watch these pt vids satifies me

[@stuartroberts6272]

I was ROBBED! Can't wait to see the finish

[@paisfr]

Bonjour Calvin , Le meilleur 😊 🚴 Thank you 👍😊😊👋

[@EntropyOCD]

Clever Hack. 40/15 is the same as my 48/18 SS. I don't know the gear inches, but small inclines are no problem. It is a good ratio to keep up with typical roadies.

[@chickenwings9117]

Nice! Thanks for the tidbits!

[@ruftime]

8:11 Extra Bling😎

[@gregmark1688]

Imho, one gear is not "good enough". I'm probably a special case, though, because where I live we have these things I like to call "hills", and even an occasional "headwind".

[@ericpatterson8596]

Great video!! Lean a lot from park tools !!

[@JaimeVargas]

Tune in 30 years from now for the Calvin tutorial on working that "old flight attendant" from sram

[@davidburgess741]

What! Oh yes, wasn't that SRAM's attempt to market novelty saddles? Most non aerodynamic as I recall. Banned by UCI, Good Housekeeping, and KZbin!

[@scootosan]

Professor Calvin if I may. I respectfully appreciate your instructional efforts and can concur with these techniques. When I referb vintage bike such as the condition you have I will just automatically trash the tire, tube and band. And the same for cables and housings and brake pads. And will the "oh going to be shiny in the sun" be on the Midterm?

[@holzmann8443]

2:15 You might want to try Pedros tire levers, they're much better than the Park ones. Other than that, great tutorial! Thanks for posting.

[@sdffsdafdsfsdfsd]

lol

[@marklenhard7034]

That would look great in a park tool video LOL

[@davidburgess741]

I don't like Park tool tire levers either. They're somehow shaped a bit wrong.

[@ElliotFlowers]

@@davidburgess741 You mean the big metal ones that you can use on motorbike tyres also?

[@davidburgess741]

No, metal levers could damage aluminum rims and would damage carbon ones. Pedros! Most plastic levers Ok, but Park doesn't seem quite right.

[@londonpickering8675]

Oddly satisfying. Thanks for posting.

[@davidburgess741]

I would have to tie my hands to not screw on a cheap Dicta single speed freewheel, swap some spacers on the axle. I'd then re dish the wheel. Problem is the nipples might not even turn on something that old and launch a new adventure. Rebuild of the wheel! No pie plate for me!

[@pinchflat]

I always just install a bmx freewheel, respace the hub and redish the rim. 40-42/16 is my gear of choice

[@ElliotFlowers]

Hello. Watching this a question came to me. Is there was way, or a formula where without having to use a chain tensioner, you can, by knowing the length of the chainstay (bb center to rear axle centre), and the sproket/ chain ring size you have...to know which rear sprocket size to keep your chain taught? The chainstay length is x. My single front chainwheel is so many teeth. Your only option is a 17 tooth rear cog. (for example). (Obviously this bike doesn't have horizontal dropouts, other wise the question would be pointless)

[@parktool]

copy this link

[@ElliotFlowers]

@@parktool what link?

[@sandy_knight]

Got any tips on which (partial) cassettes will fit on a Hope SS/Trials hub? I know they have a Shimano HG freehub but narrower than normal, so you have to remove sprockets from a modern HG cassette to fit it on. Unfortunately I don't have loads of cassettes to try out, let alone compatible shifters, and they're not exactly plentiful in the UK at the moment either! So I need to know what I'm ordering/buying will work (or can be made to work) without needing a machine shop...

[@MobileBicycleRepair505]

I want to see in the freewheel pawls. I usually spray liquid wrench in the freewheel to lube the ratchet pawls. If I want to do a better job I clean it with brake clean then lube with liquid wrench or PB Blaster.

[@manoz6194]

What about 2 speed? Use the crankset and front mech?

[@aprilshowers2277]

What is the stock rear gear ratio

[@RonnieD1970]

Calvin, I literally live for Park Tool Videos. I turned 51 last June and already converted my plastic tool shed into a bike repair 'safe space' from my Girlfriend lol.

[@DriftinDoug]

I want every PARK tool. What is the cost, Calvin?

[@hfwilkesjr]

Peek inside!

[@STEVEN-xf2nk]

Help me please I have a new bike but I’ve tighten the bolt going to the forks too tight for the crows foot and now I can’t separate the crows foot from the forks can you help me

[@npc5500]

Definitely don't open hubs if you never had an experience on fixing one. At that time I was broke young and naive to do it myself. The bike was hanging in the garage for a long time 😂

[@clearcreek69]

Opening the hub was the first thing on my mind as it said "clean me" until Calvin said NO.

[@Mersuharrastaja]

I want to see inside of that freewheel

[@jen3800]

pawls, springs and bearings . i've done practice rebuilds for restoring real old bikes. it can be done but Calvin is the master, i think he's right.

[@davidburgess741]

I wouldn't bother. Not much to see.

[@Mersuharrastaja]

@@davidburgess741 There is not much to see in anywhere in bike, but it is fun to see repair videos.

[@imposter613]

The classic repair

[@Jay-qq7so]

Bling!!🤩

[@ninjazzrhythm400]

Thats why i kept all my old tooth brushes. Just I case I need it for cleaning. Its painfull to watch cleaning that small part with a big brush.

[@davidcrowson4745]

My granny can stitch up that inner tube 😊

[@mtblife8702]

You can't pay Calvin enough

[@ninetailsnet]

that is the first time i saw that kind of free hub

[@griffon2-6]

it needs chrome valve cap

[@parktool]

That'd look great! Calvin really loves the flower cap though.

[@31.8mm]

i guess that's my first time seeing older model freehub

[@WowRixter]

It's all about hipness

[@tomskid27]

What??? No one caught that he used solvent to clean the hub after he put the sprocket on with anti-seize to prevent it from rusting back on? He should have cleared the hub and taken care if it before putting the anti-seize and sprocket on. Rookie move.

[@613.Rooster]

Never open it! But if you must,no grease. Just oil. Grease will cause sticky pawls and goast peddling. Be prepared with small tweezers and magnetic tip tools. But you know what? Don't open it. Clean it well before flushing either solvent or oil so that dirt and grit don't get drawn in with the flushing. Let it drain as Calvin did.

[@ollieb9875]

I opened it. 😱😂 I thought that 2 pin ring thing was how to get the cassette off. Not my bike. Bearings *everywhere!* I had some more luckily but it took 3 attempts and a couple of hours to get it back together 🙃 works nice for her now 👍😀

[@type17]

If you must open it, you can use a minimal amount of grease to stick the bearings in place on the races - just a tiny smear in the shiny line/centre of the race. If you're worried about sticky pawls, you can then add some lube after assembly, to dissolve the grease, but it's not necessary if you've used minimal grease.

[@PhoenixT1953]

Ive restored more vintage bikes than I can even keep track of and every single one of them that has freewheels Ive rebuilt the freewheel and packed the bearings and pawls with grease and Ive never once had an issue with sticking pawls or ghost pedaling even years afterwards

[@makantahi3731]

why would anybody sacrificed driving luxury for bike simplicity, even on flat places, if is windy it is needed lower gear ratio

[@jonathanzappala]

It’s not a collegiate sport, it’s a world sport ;)

[@parktool]

Correct. The Sport of the World.

[@joshuabuilds3051]

The condescending tone when working on bikes always makes me chuckle. Freewheels. Paws springs and bearings are irreplaceable. Grease is consumable and that rusted piece needs some. If confident you won't loose any bearings smaller than .177, go for it. Look for videos regreasing a flywheel, and you can dramatically quiet down their operation.

[@joshuabuilds3051]

Idk I ride 50-100 miles each week and i just try to save all the drag i can. Also you notice how loud other bikes are when coasting and they suddenly seem obnoxious.

[@joshuabuilds3051]

@@zygmuntthecacaokakistocrat6589 But I build all my own bikes? Just because I don't have a youtube channel I don't know what I'm talking about? Sounds about right

[@bmxscape]

@@joshuabuilds3051 if you want to "save all the drag i can" you might want to not use grease at all lol

[@bmxscape]

@@joshuabuilds3051 p.s. grease on any hub pawls is usually a bad idea because the grease will gum up and make the pawls not return.

[@MrApplesaucestuff]

reusing an inner tube? really? they cost so much money

[@herosstratos]

As a rule of thump: replace the inner tube too, if you are replacing the tyre. And fit a _good_ wide rimtape, so that the inner tube doesn't touch the rim at all. But, referring to the shortage of spareparts in the moment, there might be reasons to check, if the inner tube can be used again.

[@MrApplesaucestuff]

@@herosstratos hahaha u joking right? thanks for the explanation. also, its thumb

[@bmxscape]

@@MrApplesaucestuff in this case obviously dont reuse the tube because it has a gaping hole but for a large percentage of repairs there is no reason to spend money to replace something that works

[@БорисДракон]

[@Montblanc1986]

Here you go again with useless content and the world passes on with the launch of flight attendant from SRAM. How about helping mechanics step into the next era not this.

[@RonnieD1970]

How was that useless? Fixing up old bikes is extremely useful for people like me wbo OWN old anf broken down bikes

[@rcranes2227]

Yup. Lots of people will be happy to ride a bike like this and keeping it going in the middle of a bike shortage is definitely useful. I volunteered at a place that fixed up old bikes to give away and there's not many people who could work on similar old systems anymore.

[@deabreu.tattoo]

this attitude is the very reason why this type of video is needed: new mechanics don't want to learn how to work on old stuff, so it's up to us, regular people riding regular bikes, to learn how to work our own bikes

[@ADCFproductions]

who gives a shit about whatever new thing Sram releases? i'd rather watch Calvin fix old bikes like this, much more interesting!

[@stefannewels1823]

Such comments are (imho) like shitting next to the toilet. You know it's wrong, but soooo much fun 🙄☣
