ISO has done a good job in standardization in many fields but bicycles is not one of them. Shimano products is the closest things come to standardization in the bicycle industry.

[@damien9683]

Im convinced that manufacturers make different designs to make it *harder* to repair than actual bike performance... I remember "back in the day" me and my five friends during the vacation could put up a bicycle from scratch for a sixth friend from our leftover parts that WORKED!!

[@papamartino]

Yeah, it's a lot to take in, but it is just a starting point. Bike mechanics is probably the most underestimated of the field of mechanics.

[@rcnoob2355]

@@damien9683 I could relate to this. back then our BMX was like basic... we didn't even have special tools. all we had was an adjustable wrench, a pipe wrench for plumbing and a bunch of screw drivers and Allen keys.

Been riding and wrenching on my bikes since the mid seventies BMX days. Park Tools has always kept with the parabolic expansion of “Better” technology year after year. Although I’m not a fan of designed obsolescence the bike industry took in the late nineties, but I’m glad Park is still there with us. I still use my local bike shops for wheels and hydraulics. “A man must know his limitations”. No truer words from Dirty Harry were ever spoken.

[@monkeyking847]

I really appreciate this video. While I work at a shop and am familiar with and understand how these different systems operate, the language and grouping used in this video was very helpful in highlighting new ways to think about discussing these different standards with customers and colleagues. Ultimately making it easier for everyone to understand this somewhat confusing topic. Hopefully stuff like this can help us make words have less power to confuse in the bike industry. Thanks guys!

[@trail_farts]

[@CharlesCarlsonC3]

Calvin, you guys are terrific! I can’t express how useful your videos are. They are straightforward and to the point. They are both inspiring and pleasure able to watch. Thanks.

[@innocentiuslacrim2290]

Thank you. This was probably not an easy video to make as there is so much material and still the video needs to be compact. I really liked the branching approach you took.

[@calamardobike125]

i am building myself a bike for the very first time. i had never built one from scratch. and i think im doing a good job so far. all because of your videos

[@yabbadoody]

I was absolutely LOST before watching this video... 15 printed articles and accompanying charts had me at "nothing but confused". That said, this video (while comprehensive) made perfect sense, especially after reading about all the various standards. Visually explaining the differing TYPES and styles, and how to identify each, was a MASSIVE help in making sure I at least was "on the right track", and so at that point a quick trip to my local bike shop answered the remaining questions per size and fit (DO bring your frame! "Size Matters", and you won't want to guess). The THREADING guidance was especially wonderful, and I'm sure that brief section alone will help to save many busted knuckles and prevent stripped or damaged parts and hubs. Kudos! I'm subscribing...

[@miguelcantu8766]

Very informative!! I now have a starting point in identifying the BB for my vintage bike and verify what is compatible. Booked marked for future reference!

[@jasonjayalap]

Threaded or thread thru?

[@Spanky8402]

I pressed mine but I didn't realize nuts were inside the hole. Lol. This was a true story about a few years ago. I took it to a bike shop after that and they thought it was hilarious. I somehow had a few things shoved into my frame, while my bike was stolen by a friend that I no longer talk with. All kinds of scrap metal was falling out of it and the bike ended up having a crack on the bottom bracket and the angled tube going up to the handlebars and the bike was scraped, sadly. Still a funny story, even though it was a sad story with my bike.

[@GinggaSnap]

Hello Calvin, your videos are so helpful. Thanks!

[@GNX157]

What a nightmare. Manufacturers should be required to affix a permanent label to the frame in the BB area that denotes what type of BB is used, as well as a QR code that can be scanned that will take you to a web page with a more detailed description. That same QR code should be on your warranty card when the bike is bought new.

[@mikieson]

agree..same with cassettes/freewheels..When you buy a bike all the tools should come with it to repair these things as well.

[@FarmerFpv]

That will never happen, It's the bike industries bread and butter, lol

[@yosephalabdulwahab4151]

There are only 3 types of frame bottom bracket shells tho, press fit frames, threaded frames and thread together frames. Its not France manufactures its the groupset manufacturers that make all the bottom bracket standards

Thanks for posting this vid. Recentily got a folding E bike and I think somehow sand got into the bearings on my bottom bracket. Guess its from riding through puddels from the winter rain. I also ride over dirt trails sometimes on my route. I have the typical 3 piece crank most bikes come with & the crank arms are on there pretty good so I guess I'll need to get a crank puller tool.

RollinRat The VHS - Beta phenomenon is human nature. Threaded BB is making a comeback because it works well enough and riders like to fix their own bikes. I think some bad designs become 'standard' for a given manufacturer because they have industry heft and go with things that are easier to build than for the home mechanic to maintain and repair.
