Calvin is such a natural teacher, a true imparter of knowledge. Great to watch and listen to.
Jim, that's right and I didn't hear one peep out of him about climate change and how we're all going to die in 12 years.
J4000x why bring politics into this discussion- sparky
Yes! that`s is the point, he is a natural teacher.
A very good teacher.
@@MrJx4000 😶🌫
WoW. He takes off with a live audience.
I could listen to Calvin all day .such a passionate knowledgeable guy and a credit to park tools and if I'm honest the main reason I got in to buying park tools .
A legend
Agree, me too
Same👍
is there anyone who hates that guy lol
every video peopel love him
Park Tools' spokesman😉
Well "spoken."
John Tyler noice
You have got to be kidding me
I had a professor like Calvin when I was in college. I literally took every class he offered- two of which had nothing to do with my major. Cal, keep doing your thing man!
finding someone that has natural ability to teach is awe inspiring. i totally understand going out of your way to learn from that person
There's always that one know-it-all who won't shut up from the front row...
Sounds like seth bike hacks
@@lukasagnevik1974 That's what I was thinking, too. He's exactly the kind of guy that would do that, too.
You guys do know he's literally asking them to give answers right
@@tonisbalonis4823 It's okay to ask the audience, but I'm not talking about the audience as a whole, I'm talking about that one guy who shows up at all of these kinds of events, and is genuinely annoying and disruptive for the sake of his own narcissistic interests.
He sounds like he is teaching kindergarten kids. Priceless!
Entertainer, educator. Calvin is the man of so many trades.
That's why park tools loves him

2 a.m it was supposed to be movie night...watching Calvin videos instead, no regrets oh and i can't wait for the parts I ordered today to change the cassette, another master video guided by Calvin
Best bike mechanic in the world. Best bike tools in the world.
Oh man being an engineer and a pasionate about cyclists, watching this is like relating academics to passion ... What a great apetite to mind and heart ❤️ ...
Calvin is such a nice person. Would love to have all the teachers like Him. Great man.
I will love to work for free with you even for 2 days a week, but I live in the caribbean.
😮💨
I does learn so much from you all park tools guys.
I does save so much money thanks to you.
In the space of his studio, he is a passionate educator but with a tendency towards some monotony, but once in the open air you get to see a different Calvin Jones. Almost an stand-up comedian. Wonderful teacher.
"-If you don't get broken spokes, you're not riding enough."
🚴🔥🔥🔥🔥
I want Calvin to come cycling with me... Of course his backpack will be full of tools and spares...
Thanks Calvin and Park Tools for doing such a great job teaching us. Love it!
Calvin is the heart and soul of Park Tools.
dang it! It's already my sixth time breaking a spoke. At this point, I already spent more time and money replacing each broken one as compared to getting new sets of spokes on my rear wheel. Had the wheelset made less than 2 years ago.
Should have had my LBS re-lace the entire wheel with new spokes.
@@RealMTBAddict the rims are fine, the spokes not so much. I had the spokes replaced with a better set and they are doing great so far. I've riden almost 1000km since the rebuild. Mixed paved roads and single track
@@RealMTBAddict I got the same rims. Laced it with pillar racing spokes
Simple, concise and informative.
Very good videos all over the channel, they are entertaining, and they are extremely helpful in situations when you need to fix something on your bike.
This guy is seriously f'n brilliant.
He genuinely knows his stuff....and can teach!
Subbed
Gotta respect the hustle 💯
He's my favorite park tool guy
Verry nice ! Never though i would have watched this whole video but your quite a character ! Ill check more parktools videos !
Seaotter is unfortunately way to far for me but I'd love to watch Calvin and Truman all day long teaching about bike tech. Your TH-cam videos teaches thousands of home bike mechanics how to solve little and little bigger problems. Thanks a lot!!! Greeting from Germany 🔧
Thank you Calvin.
I like to watch this guy, he really has been teaching me a lot about the standards of tools and mechanics of your bicycles performance. I have broken five spokes in 4 months just this year alone and take it in to get a Spoke fixed and guess the mechanic just replace the nipple but I have never seen the mechanic use a Spoke tensioner. so I'm going to go in and get the whole back will be strong and insist that a Spoke tensioner be used and questioned where the tension is at to ensure that me as a customer get top-notch. I really like watching Park Tool Company
Wow...I'm becoming a fan of Park tool :)
This guy is brilliant!
Awesome & Thanks Sir 🙏🕊
I really love Calvin Jones teaching...
That heckler is painful!
great video! thanks!
Gold video! Greetings from Colombia man✌🏻
Brilliant video. Im converting some steel rims to alloy and snapped a few spokes in the process of dismantling the wheel. Even though i dont own any park tools at the moment, i use the youtube channel all the time!
Nice demonstration 🚲🔧👍
I'm riding my cheap road bike with a missing spoke. Thought of replacing, forgot and did a 60 km tour. Guess I'm good no repairs needed :) Funny thing it's a rim break road bike and the wheel is still true, I blame it on the heavy duty cheap rims.
Park Tool makes great videos! :)
Calvin, please come to the New York Bike Expo!!
Had to get my rear stock wheel on my Canny Quick4 re-laced. Was popping a spoke on every other ride. DT Swiss.. Problem solved.
"how do they bend the spoke at the end? That's right, they bend it. Don't worry about bending the spoke..." Hahahahahaaaaaa LMAO
He must have been a school teacher and his informative and entertaining talk deserves a much bigger crowd in real life, but I guess compensated by 120,000 crowd on youtube.
Good video 👍
calvin is a legend
For my clients , buying a prefabricated wheel replacement is normally not an option . They get a prescription wheel that better meets their individual needs instead .
that was fun to watch !! with some free gifts as well ?!?!
Great job park tools ! I learn alot from them !!
Calvin is hilarious...🤣
I wish I had your knowledge
Calvin is a true God of bicycles.
Grate teacher
What the hell would we do without Park Tool?
Keep the correct spares on hand in your breakdown kit with spoke keys .
Where are these being held at , would love to meet the legendary Calvin
Nice Bevis impression! 3:51
MASTER!
I broke a rear spoke yesterday and fatigue wasn't a factor. Only had about 22 miles in on a 45 mile ride. The spoke broke in half and it was the strangest thing that ever happened to me on my bike in 50 years of riding.
Sounds like a fault in the spoke material. It happens sometimes.
Nice one, one thing I noticed is he didn't explain that the removal of the cassette is actually a lot more difficult than it appears here (pre-loosened) due to needing to apply opposite rotational force on the sprocket whilst loosening lockring, ideally with a chain whip, an old chain or other tool.
Imagine if all teachers at schools is like calvin, he makes learing fun.
Hello, are there any seminars like this in toronto?
So interesting to read the comments after learning through watching. I can't stand the presentation and admire everyone else who can get up to get the job done
J'ai bien aimé . Merci . ) 👍
Wholesome
I'm very unknowledgeable but live in New Zealand. How am I going to get my clumsy hands on a PT bottle-opener for getting things wrong?
Have a dirt jump bike and you broke a spoke near every month jumping..a bad 180 can break like 3 spoke ...
Just sat in the shed truing my rear wheel for 6 hours only to overtighten a spoke and snap it. It was previously bent
A learning opportunity!
Very instructive, as always ! :D
The only think I do complain about Park Tool is their prices. :/
Park tools are good quality, very affordable and American made. There are much more pricey options out there! You dont want to buy cheap tools either. Tools are an investment. They save you money.
When you buy quality, you only complain about the price once.
As a former machinist, precision tools especially German and Swiss( the best) get insanely expensive. I have probably $20000 invested in tools. If you use tools everyday get the best you can afford. Preferably with a good warranty. I wrench in a bike shop now for fun and laughs. We use Park, Pedro's and Craftsmen tools. Theyre just fine!
Avoid cheap, Chinese junk, it often needs to be modified to be functional when it's brand new and only 'works' for a short time.
Tools are an investment. Mine save me time. Time IS money or at least time Id rather spend riding!
10out of 10for making bike repairs fun David bolton england😂😂
Frickin' hilarious!
THAT WAS A GOOD DEMO FUNNY SHOW MAN . ACTUALLY I BROKE A SPOKE I BELIEVE PUTTING THE ONE UP BIKE LOCK ON MY BIKE WHILE IT BEING ON THE RACK WITH FRICTION MOVEMENT OF MY CAR .OR IN THE WOODS ON MY FAT TIRE E BIKE. OVERALL I FOUND OUT I HAVE TWO BROKEN SPOKES SO I M NOT RIDING THANKS TO YOUR VIDEO ABOUT THE RIDE QUALITY.
I hit a stick that took out 75% of the spokes in my rear wheel - way more of a problem than fatigue
Hmm that’s one hell of a stick! What spokes were you using?
7:38 metric rules!
Spokes can break easily if a person weights in at 185 kg but the specification says 130 kg maximum. However, even a comparable light person can break them if unevenly or unadequately tensioned.
+what also floats in water ?
-small stones ?
I seem to break only j-bend spokes and no straight pull spokes. Is that a coincidence? Had a couple last year, all at the rear non-drive side braking at the bend with 3 different wheels.
coming to riis park queens,long island,brooklyn?
So how do you get to the sea otter festival from Marina without a car??? From out of state and don't drive... Hitchhike??!
A fine [Englih] teacher.I must reo
comend him to my pupils .
I broke a spoke now what?
LBS: just buy a new bike. We have a lot of good bikes you can put on credit.
Reminds me how the bike mechanic at a shop I visited didn’t know what a bottom bracket was and claims they don’t come in different lengths. He highly suggested I just buy a new bike for $5k instead of a $25 bb for my chain ring to be distant from the frame.
15g spokes on new brizon wingflyer 16 broke on rockaway beach boardwalk; no parktool spoke threader in local bike store
mmm I use 24 sopkes, I have one broken already...is it 23spokes like too little spokes to ride safe? wheel already deformed like no 32 hole well will, th ematter here is that I had to order a few spokes its christmas time so I´ll get them i a few weeks probably
Calvin is the bike show rockstar! I'd love to meet him.
I ride mountain bikes, rocks flip up and hit the spokes all the time,,,, and snap !
Should have headed over to the Spinergy booth to see glass spokes, well polymer fibers in glass phase. They also erroneously claim they don't stretch, but clearly they do, as you say stretch is needed to tension a wheel. Solid silica glass would make a poor spoke as any bending would easily break it, but it's still an elastic material. Could use it as fibers, but there are better choices, such as Spinergy's.
We have a few sets of Spinergy wheels here actually. Pretty nifty.
Unless you're racing, proprietary junk makes very little sense. Neither does 'reinvention of the wheel'. Bicycles 'should be' simple, reliable, affordable machinery. That's what the vast majority of consumers actually 'need'.
Most of this new fangled proprietary junk is more difficult to repair, more expensive or requires special tools. Most real world, experienced and practical wheel builders and mechanics know this. We have dozens of bikes sitting unridden in the shop WAITING a week or more for ALL SORTS of proprietary junk available from only one source.
People complain about the wait, so my advice is: " buy another bike today, then you can ride today!" It's a great means to sell more bikes in this neighborhood, believe it or not!
When you break a spoke, sometimes you're traveling far and wide. Broken proprietary junk potentially ruins a big event unless you planned for the worst.
The best thing to do is use ONLY J bend stainless spokes that any decent shop stocks around the world. Many good shops can cut and thread a j bend spoke to the correct length for you.
So. Much. Shit. Talking. In the crowd. I love it!
broke a spoke !?? omg!!! buy a new bike! :D
I just had a minor accident recently and i notice when i got home one of my spoke bended, can you still straighten it with a pliers and just true the wheel normally or do i need to replace spokes?
A small bend in a spoke may increase the tension but is typically not a major enough issue to replace a spoke.
I was driving on road my mtb for short period and than i stopped after maby 500 meters and i saw that 1 spoke was missing
How I broke a spoke: drifting at 20 mph which I had done before on a thinner rim and was fine and the spokes snapped and the rim bend in half
DId he say "Could we have avoided that....Correct, by not having the kid." ? LOL
What about us that break a spoke that comes loose from the rim and half the thread of the rim comes out with the nipple? :)
I broke like 8 spokes and the wheel just wobbled like a loose cone
What breaks a spoke?
Casing a 40ft double with a hardtail.
hey, I recently broke a spoke and my whole bike started shaking when I ride it with no hands, do you think its because of the broken spoke or the wheel being a tiny bit bent
Yes, it is both of those issues. Its kinda chicken and the egg type thing but in this case the spoke breaking came first then the bend in the wheel was introduced leading to shaking while riding without your hands. Repair the spoke and bring the wheel back to true and your woes will be resolved.
I am 6'5" and 300 lbs. I break spokes all the time. Using your 3 strikes rule I would be rebuilding my wheel ever 6 months. Other than losing weight is there anything I should do to lessen the spoke breakage? Are there better brands of spokes?
There are different grades of spokes that may help you out. A good builder with a proper rim and hub will be able to build you a long lasting wheel. A robust rim will help the spokes out quite a bit.
@@parktool Thanks guys!
7:49 or work out the spoke length by ERD of the rim
There are several parameters involved when calculating spoke length:
ERD
Number of spokes
Number of crosses
Hub flange diameter
Width between flanges
Offset of flanges
Asymmetric rims?
Feynman of bike mechanics
Took me 5 broken spokes before I gave up and bought a better made wheel.
Just not worth dealing with the original junk wheels.
see kids, learning is fun :)
If you use the TM1 to tension spokes? can you use it on bladed spokes in the same way?
Yes, You can use it to MEASURE tension. You and the spoke wrench need to do the tensioning!
@@rollinrat4850 I am aware of that I think what I meant to say is do you use it the same way on bladed spokes as you do on round ones!
Nige Johnson Yup, I was trying to be a smartass! You do need a slotted ‘spoke holder’ to hold spoke to prevent blade from twisting while you tension the spoke.
You can obtain the specific tool or saw a slit in a hard piece of wood or plastic. Either will work fine.
@@rollinrat4850 I am aware of that to and I do own one. I am talking about the TM1 Flexing the spoke to get a reading. The only way I see it is the TM 1 Can only flex the spoke in two directions as opposed to all round on a round spoke.
Nige Johnson Youre over thinking it. Use the tool on the thinnest cross section of the spoke. Thats the area that is most effected by the tension. Similar to measuring tension on the thinnest part of a butted spoke, in the middle.
Whenever you look at the chart that comes with the tool you use values given for the thinnest section on spokes you’re using. If you have 2.0/1.8 spokes, use the values for 1.8.
Ive built wheels for almost 40 years, when I started I learned from an old wheelbuilder. He told me NOT to tension wheels very high. High spoke tension doesn’t make wheels stronger. It cracks spoke holes or worse. I followed his advise. Ive always tensioned to the lower middle of the range given. Many other good builders do the same. I DONT use road hubs (130mm) requiring lots of dish, like 11 and 12 speed. They may work ok for awhile but wheels with large tension differences side to side dont last very long or take a real beating. Its why MTB standards keep getting wider, some road/ cross wheels are now 135mm. Theres a reason why a broad, more equally sided triangle is a stronger geometric shape compared to one with a shorter base.
Wheel strength, reliability and long life are most important to me. Wheels are a MAJOR safety concern, lightweight and # of gears are a lesser consideration. WHAT WE ROLL ON is MOST important!! I have zero dish, symmetrical singlespeed wheels that are pretty light and I can beat them in rocks on 33c tires. They very rarely need truing. Personally Im not too nice to my wheels!
Ive built hundreds of wheels, they rarely go out of true. Out of all those wheels maybe a dozen spokes have broken, mostly disc wheels. My wheels have only broken (mostly dented rims and flat spots) when customers or myself have had accidents or used the wheels doing dumb stuff they werent designed for. I love ‘underbiking’ ! I ride mostly very simple ‘cross and singlespeed type bikes outside their intended usage. It makes familiar trails new and challenging!
Sorry for dragging this out. I love working on wheels. The spoked wheel and the inherent strength of the structure fascinates me!
