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.

God. I came to learn. Now im more confused than ever.

[whiskywhippet]

I always though BB standards were confusing before watching this video, now I know they are!

[ladams]

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!

[monkeyking]

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!

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.

Honestly seeing a cut section of a BB in real life is so helpful/ legit. Thankyou!

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.

4:46 That was me back in high school where I almost forgot the next words to say when presenting to the whole class.

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!

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...

5:30 - 5:40 is the most important part. Just undo the non-drive side (counterclockwise) then look and see what you have.

[innocentiuslacrim]

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.

[calamardobike]

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 <3 thank you my dudes

[rikvermar]

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

[shamoy]

Based on your videos I purchased the correct bottom bracket assembly and installed it in an hour. Thanks.
