My crank arms woble but the crank bolt is tight what is my problem ??????????????
Wow, I think this video has more material covered than most of the useless linguistics/diversity classes I had to take and write essays for, except this video is actually very useful and under 7 minutes packing it all in very well!
As a mechanical and aerospace engineer, there are over a billion ways to solve a problem, and it looks like bicycle companies never could settle on one… well, at least this guy covers them well! Great video, you could have a degree in just bicycle repair from all these variations, I’m glad they got an expert on this subject, makes my life easier, thanks!
You didn’t mention my favourite…. The wafty crank!
Best channel ever
If it doesn’t fit, use a bigger hammer.
Hi! I have an old bike with the Non Self Extracting crank on it. Is there any way you can post a video of give me information on how to remove it? thanks!!
This guy is so cool
Top Video! You are great 1a+++!
I really want to appeal to the manufacturers to come up with some new, different standards – there just aren’t enough.
What type of system is a Shimano FC M391 crank ? What tool will I need.
Another great video! thank you!
I just got myself a pcs-9 and have a number a jobs lined up.
i could do some of it but i gotta be honest… you’re way to smooth at explaining things in simple terms and i just love your passion for it all – can tell you’ve been in this business for a while.
park tool for the win:)
love from the UK
I need park tool in canada !!!
What if your cranks are two piece but don’t have the pinch bolts and just have an 8mm hex bolt, and are not Campagnolo…
that dude is a strick looking guy, if i were still a child i would probably scared to death just by walking down the path way of his house hahahaha,,
anyways good channel and a lot of informative thing you got here
ok I’m think about changing crank type. what kind should I use in the list above
Hi sir, can I use roadbike crank on my mtb? I’m planning on making it hybrid.
Why so many different crank designs it was just a crank extracter tool for every make and that’s all you needed in your tool box !!!!
i am a noob at bikes and stuff and basically i want to put on a new crankset on my mtb bike and i guess i have a 3 piece one.. can i put on a 2 piece one on it? or are they not interchangable?
btw i want to do this all by myself without the help of a bike shop.. for fun
Calvin Jones is my dad
Why so many 3 piece cranks? We need allot of tool just the remove the one you currently have
Hello. I have the following crank bolt linked here: https://i.imgur.com/F4TpVKV.jpg I’m not entirely sure which product to use for this as most seem to rely on the bolt being removed with an allen wrench. The crank arm is a Raleigh Suntour Superbe part as far as I’m aware, though the bolt says Sugino.
My mother? Let me tell you about my mother
Awesome video!
Hi Calvin, great video, I like your videos always with explanations on how it works before how to do it. The left crank blot of my bike is lost. I like to find compatible bolt and fix it myself. How to figure out which bolt? The arm is ISIS drive type. I guess cap size and axel thread size are important. I see online stores carry blots for M8 and M15 etc. but I don’t have knowledge on what they mean and how to determine the blot I need. Thanks.
I would love a similar video for bottom brackets.
On the 2 piece crank my spindle is on the non drive side arm. Is this the same?? They are called Race Face Chester 38x24T, 170mm
Great presentation.
great job
fuuuuck campanolo.
Calvin, I’ve started rehabbing bikes at our local bike co-op. I had no idea how many different bikes and components there are. Your videos and your Big Blue book keep me productive and a whole lot less frustrated. Thanks for your straight and understandable instructions!!!
So cool, my crank looks nothing like none of those, and I need to replace it. Screw my life.
campagnolo can’t even standardise 2 crankset types, they need 3 of them…
I have this crank set Raceface Æffect Cinch w/ Steel 30T "Narrow Wide" from a diamondback atroz 3 2018, which crank puller do I need
CCP-44
CCP-22
I disagree that the list will keep growing in time, I believe it will shrink. As this is just another sport driven by racing fashion, in racing what eventually prevails is what is lightest and works best, that is what separates the winner from the losers. Eventually almost everyone is winning by one system, the best. Then to sell bikes you have to simulate the same exotic system. You can simulate titanium with steel just by using more of it.
Otherwise it is a great video, we can only disagree on speculation 🙂
Hello, I just bought a vintage triple SORA crank-set but I don’t know what length of bottom-bracket spindle I need? It’s for my old school 8 speed road bike 45 cm. All I know its a Square Tapper JIS, English thread 68 Shell. : /
Yep, my bike’s got a cotter pin crank with the presspin, I believe we call this last piece of metal a ‘spie-tje’ (I’m Dutch) and this spie-tje is completely stuck, I’ve been banging it for 20 minutes now and it’s freezing outside so my fingers are frozen… I’m not very happy right now.
so many kinds of nuts and bolts……
Hi sir. Wouldnt there be any serious issues if I use an 8 speed crankset ( shimano claris r2000 to be specific) on a shimano tiagra 4700 10 speed system?
Can I use a 9 speed Tiagra double crankset with an 8 speed Claris rear derailleur?
4:30 that’s a nice way to get FBIied while repairing bicycles
Great info, thanks for sharing
Is it possible to upgrade a square type crankset to a hollowtech type? Thanks.
Excellent video Sir.
I don’t see my crank, it’s a 2017 Cannondale Quick Carbon 2 with an FSA crank that has a hole about a 1/2 D with 12 splines with a spanner type flat in front.
What kind of crank is a race face SixC?
Hi, and thanks for the video, i want to build a 11 speed MTB with one peace crank, most likely shimano type, what crankset you recommend for this?
My crank type inst on there?
the video series’ from park are legendary. thank you!
Hi Calvin I am your biggest fan. Thank you so much for making this helpful video.
Difference between boost crank and non boost crank? I.E I know the axle is longer but by how much? What is the boost standard length.
