consult the 'professionals'. all shops in the uk seem to be completely inept and rip off merchants. this channel is by far superior to any shop in my locality.
There are 100 bottom bracket standards Engineers: This is ridiculous! let's create one standard to unify all standard. There are 101 bottom bracket standards
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.
Mike Sadlier I hope this comes as soon as possible, this shit pisses me off. Why tf do I need to do an hour of research to find the tool I need then search for it or order it. It’s a goddam bicycle!
Pacific Cycle has been so unhelpful in answering questions on their bottom brackets. Thank you Park Tool for doing an outstanding job on this video series!
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.
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!
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!!
@@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.
@@rcnoob2355 IKR!? So little tools were needed back then NOW when I ride I carry two allen key sets and several different tools out of fear that if something happens and I couldn't fix my bike I'd have to resort WALKING home!!
Just watched this again, and grinned when Calvin said 'journey', pretty sure he's taking the Mickey. I'm so glad that there are people like Calvin in the world, people who actually know what they are talking about!
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.
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
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.
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...
love the comments for this video....they help remind me that we are all in this together....thanks guys for the video....its not your fault ...I think we all agree on that
You're both knowledgeable, accurate in your details, and very clear in your explanation of information concerning bottom brackets. I've learned from this video and am thankful to you both for it. Please continue to inform us as you're doing.
i am 40 and took my 1st bike apart when i was about 7 and must of repaired 100's of bikes ever since, i own a "Dirty Jo" mtb which was custom built by Henry Burton Cycles roughly 15yrs ago, shimano deore xt hydralic brakes, gears and wheels - light as a feather - just under £900 new and for 15yrs has been my pride n joy which i have serviced myself and still looks as new. But my nephew who has a 2016 Specialized downhill bike which needs a few bits replacing asked me if he gets the parts can i fit them, yes i said confidently - but after having a quick look i was so surprised how things have changed, you could fix any part of a bike yrs ago - now its sealed units and 10 versions of what the part could be
@RollinRat I commute by bike 18km to and 18km back home. It takes commitment and patience. I ride steel with fenders, hub dynamo and I ride in the worse weather conditions. I'm 55. I also work shifts. But since I slid out on ice twice and spent one morning after night shift 😴 , 3.5 hours getting home. I was a mess, plus I noticed my rear schwalbe marathon plus tire was flat because I purposely let a little air out to get better traction. Snow was too deep to realize my mistake. And I felt like I had jetlag. So I borrowed a 🚗 car and drove it and filled up the tank afterwards for 55 Euro. Meditating on how the auto also has big greed. Car insurance, inspections, burned out headlights, cracked windshields, tires for winter and summer all monitored by the car mafia with help from police, environmental professionals, and your "got you by the balls" mechani. I try to do my own bicycle repairs. But the bicycle industry has to make money. It is just not as apparent as the auto industry. So I am going back to my 720km per month commuting. It's worth it for me because I can save a shit load of money, and I really don't like cars. I am a bit of an oddity at work. But I get it. My legs get it. It's not a chore. It's a way of getting to work. It's my way. Going to try single speed someday because of the anger to the bike parts of too many gears ⚙ 😑 on a bike and I use only one or two. Derailleurs just plain suck. And IGH are strange. I can keep my Derailleurs in tune. But it takes time.
6:53 This is THE MOST, I mean THE MOST, stupid LINE for this, so called, "CIVILIZED" Humanity. We can't do ONE DAMN STANDARD RIGHT, and solve, ONCE AN FOR ALL, the Ecological and Ethical ISSUES (MAAAN THERE ARE ISSUES HERE !!!) on BYCICLE MAINTENANCE !!! ( or should I say: BYCICLE FUCKINANCE ?!!) . 😠😡🤬😈👿 6:59 Hahahah !!! Just don't !!! Don't make me laugh !!! 🥴😤🤮
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.
This is one of the few warning labels that actually makes sense, and I deeply respect it for some reason. Like I would if I saw the following sign. Warning/ aschtung! Mine field ahead! and a skeleton symbol under the text. 🙂
You guys are simply a life saver!! I'm certain I am up to over a thousand dollars of savings from being able to do my own work! And investing in my own tools is so much better than paying for someone else to maintain my bike! THANK YOU!!!!!
Nicholas Wasbotten glad it worked for you man, but the hours of figuring out what kind of parts your bike has and then buying expensive parts takes it own toll. At the end of the day all of these complexities are there just to take our money, and Park Tool is probably profiting and supporting this shit.

You guys just saved me a tonne of hassle, big clearance difference between INTERNAL SPLINES WITH ISIS DRIVE SPINDLE and 20 INTERNAL SPLINES WITH SQUARE SPINDLE. Unfortunately all the BBT-32 appear to be coming from the USA with heavy postage cost, will consult local bike shop. Cheers guys, your a gem!!
I just had to buy a new tool for my DUB BSA bottom bracket. I took a look in my tool bin and I counted at least 10 BB and crank removal tools that no longer fit any of my bikes.
Great video, thanks. I came across it as I need to replace my bottom bracket. I guess I forgot that when I first had a bike some fifty years ago it was cheap and cheerful . Now they are expensive highly engineered machines. Having watched this I think I'll take it into the shop! :-)
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.
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
I managed to get my wife's eccentric BB apart and together again today with help from video's. I didn't fix the clicking noise but I was happy that I managed to reassemble it without making it worse :/
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!
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.
@@wammo12345 yep, you see this all the time in automotive engineering too: difficult repair procedures because the car was designed to be easily assembled, not easily repaired
Hi there two I come from germany.. I''ve got a Shimano bottom bracket, called BBR60. I habe a learned much about removing and Installation.. Thanks much.
Thanks for the videos guys. Still confusing from the so many standards. Bike Mfgr. Let's choose one best standard and go with one. It will help you sell more bikes!
what a cute couple ! ha ha, just teasing, but yeah you guys rock ! pure inspiration. all i think of are thread counts, bolts standards, torque settings.... i dream in grease.
@@JakubAdamus I was at my bike shop today and bought some tools with the intention to: true my wheels, remove and re-grease the wheel bearings, remove and re-grease my bottom bracket for a 'nice smooth ride' as I have had my bike for about 13 yrs now and I'm sure its' nicely gunked up,.... After watching a few of these videos on the 'How To'. I've rationalized that smooth bearings for a 'nice ride' are for PUSSY'S, and my legs are gunna get 'UGE leaving my bike the way it is! XD
Señores Parktool en primer gracias por los excelentes videos que han desarrollado y en segundo lugar, quisiera pedirles que puedan generar material en el idioma español. Saludos desde Chile
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.
In the late 70s, i had a basic Schwinn Varsity bike, $100 or something. A french man with a $10,000 custom built bike, where measurements of his whole body were used in the design, 35 years old, semi pro rider his whole life, asked if i wanted to ride with him. I said yeah, it was like a 50mi ride. I was like 16. He tried to lose me and leave me in the dust, riding in highway lanes, etc. But he couldn't. It wasn't easy, but i could keep up. The cost-benefit ratios of bicycle technologies have generally been negative since then. I blame the monied interests that have turned a mode of clean+free transportation into an extreme sport for the rich.
