These Park tool vids with master mechanic Calvin, are clear, concise, and thorough. No cussing, no juvenile antics, no lousy music, no drama. Good lighting, close ups and a stable camera. Bike mechanic vids just don't get any better than these from Park tool. Thanks Calvin and Park tool!

i just want to throw it out there that your videos have consistently given me exactly the information I required each time I had a question. At this point I go directly to your channel with my repair inquiries.

"Cover with more grease, " is my new catch phrase.

I appreciate the lack of standard snobbery. Cup and cone gets the same treatment as ceramic bearings.

I was complaining about some noise my bottom bracket was doing for almost a year. I respected the takeout so much, i didnt even try to do anything. This Video was an awesome guide and after just deinstalling, good cleaning and installing, the noise was gone!!! Im so proud of myself having this experience and was able to learn how to adjust bearings... was real fun! Big thank you :)

I always insert park tool in the search bar if ever they had a service video about certain bike parts. Very well explained.🙌🏼

I think I severely underestimated how much grease I need.

If you don’t have a headset press just use a bolt with big fender washers to keep the cup wrench on the cup

Very useful and detailed video, without superflous commentary, to show how to install and adjust cup type bottom bracket bearings

Calvin and Truman are very knowledgable. AWESOME Thank you!

[aaronellsworth]

This video is just what I needed! I knew my bottom bracket had developed a lot of play and needed rebuilding. I especially appreciated the advice on when to replace the parts.

[philinspain]

Completely demystified the process. Fantastic.

thank you - very helpful - I still think that a cup and cone bearing which is in good condition feels better to ride than any of the modern stuff - probably because of the 1/4" ball bearings - I prefer loose balls as you can get 11 in - the cages normally have 9 or sometimes even 7 which puts more load on them - of course they do need regular maintenance especially in wet and dirty condition but if you do strip, clean and regrease often they are fantastic!!
