    My crank arms woble but the crank bolt is tight what is my problem ??????????????

  2. Jake Garrett on June 25, 2019 at 6:58 pm

    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!

  5. Alex Paulsen on June 25, 2019 at 7:01 pm

    If it doesn’t fit, use a bigger hammer.

  6. James Gavino on June 25, 2019 at 7:01 pm

  9. Spitch Grizwald on June 25, 2019 at 7:04 pm

    I really want to appeal to the manufacturers to come up with some new, different standards – there just aren’t enough.

  10. red45935 on June 25, 2019 at 7:04 pm

    What type of system is a Shimano FC M391 crank ? What tool will I need.

  11. kokooos deathmolish on June 25, 2019 at 7:05 pm

  13. R3PLAY-Minecraft&More on June 25, 2019 at 7:09 pm

    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…

  14. Steal Hart on June 25, 2019 at 7:10 pm

  15. aflick 101 on June 25, 2019 at 7:11 pm

  16. Mugiwara Luffy on June 25, 2019 at 7:12 pm

    Hi sir, can I use roadbike crank on my mtb? I’m planning on making it hybrid.

  17. Dean Stanley on June 25, 2019 at 7:12 pm

    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 !!!!

  18. bruno baumanis on June 25, 2019 at 7:13 pm

    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

  19. hgpo27 on June 25, 2019 at 7:14 pm

    Calvin Jones is my dad

  20. //ngy on June 25, 2019 at 7:15 pm

    Why so many 3 piece cranks? We need allot of tool just the remove the one you currently have

  21. MaladjustedPlatypus on June 25, 2019 at 7:16 pm

    Hello. I have the following crank bolt linked here: 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

  23. Vali Munteanu on June 25, 2019 at 7:16 pm

    Awesome video!

  24. Tan木匠谭 on June 25, 2019 at 7:18 pm

    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.

  25. Alexander Björk on June 25, 2019 at 7:19 pm

    I would love a similar video for bottom brackets.

  26. Jack Beames on June 25, 2019 at 7:23 pm

    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

  27. Eduardo De Leon on June 25, 2019 at 7:24 pm

    Great presentation.

  28. Ilya Botsarov on June 25, 2019 at 7:24 pm

    great job

  29. ThumbsUpMan on June 25, 2019 at 7:25 pm

    fuuuuck campanolo.

  30. David Sonnen on June 25, 2019 at 7:25 pm

    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!!!

  31. dontmindmeimonly12 on June 25, 2019 at 7:25 pm

    So cool, my crank looks nothing like none of those, and I need to replace it. Screw my life.

  32. Martin Skof on June 25, 2019 at 7:26 pm

    campagnolo can’t even standardise 2 crankset types, they need 3 of them…

  33. Fabricio Coto on June 25, 2019 at 7:27 pm

    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

  34. PermaKulHurTur on June 25, 2019 at 7:30 pm

    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 🙂

  35. Ricardo del Rey on June 25, 2019 at 7:31 pm

    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. : /

  36. Henry Beenh on June 25, 2019 at 7:36 pm

    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.

  37. Sam Lee on June 25, 2019 at 7:36 pm

    so many kinds of nuts and bolts……

  38. Arman Celorico on June 25, 2019 at 7:36 pm

    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?

  39. Joseph Richy on June 25, 2019 at 7:37 pm

    Can I use a 9 speed Tiagra double crankset with an 8 speed Claris rear derailleur?

  40. PetrosRZ on June 25, 2019 at 7:37 pm

    4:30 that’s a nice way to get FBIied while repairing bicycles

  41. That 70's Schwinn Vintage Bike Channel on June 25, 2019 at 7:38 pm

    Great info, thanks for sharing

  42. batang gueño on June 25, 2019 at 7:39 pm

    Is it possible to upgrade a square type crankset to a hollowtech type? Thanks.

  43. Tony Bennett on June 25, 2019 at 7:41 pm

    Excellent video Sir.

  44. ajaopify on June 25, 2019 at 7:44 pm

    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.

  45. Chase Deery Drumming on June 25, 2019 at 7:44 pm

    What kind of crank is a race face SixC?

  46. Wael alshami on June 25, 2019 at 7:45 pm

    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?

  47. Michael Shields on June 25, 2019 at 7:45 pm

    My crank type inst on there?

  48. Tom Abramoff on June 25, 2019 at 7:46 pm

  50. SunzOffski on June 25, 2019 at 7:52 pm

    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.
