If you want nitpicky: 1) You don't need to break the chain to remove it from a 1x drvetrain. 2) You don't need to remove the cups from the frame to replace the bearings. And 3) Yes, you should almost always grease or otherwise appropriately treat the surfaces of press-fit bearings and other press-fit fittings to minimize galvanic corrosion and allow future removal without undue force. . . regardless of the internet's failing to adequately educate people in this regard.
Just came to comment on the press fitting - in the machine shops I've worked in / designed parts for, lube was a requirement after one too many had to be chisled out of bores, not for galvanic reasons, but for galling / galling related misalignment causing fractures during insertion. I'm not 100% on galling being an issue on bottom brackets but assuming the housing is aluminum, and the outer race of bearings are steel... that can be a bad time. Professionals can do it without and have no problem, setup being key, but I've seen too many use rubber malets to 'walk the rim' to get them in.
Very informative, it is very nice to have a set of tool like that to do a specific job, most particularly you have a bike shop or a cycling team. However, for personal use with 2 on-road bikes, it might not be an economical option to keep such expensive tools where you will only replace a bottom bracket/bearing (specific for this tool) once every 2, 3, or 4 years. I considered getting a kit but my decision steered me to take another direction. Great video !
Best tutorial video ever
Thank you! I'm glad it was helpful!
Fantastic video!
I just lift the chain off of the ring with out breaking the chain much easier.
Fact👍🏻
Very helpful. Thanks.
I'm glad it was helpful, thanks for watching!
Good video. Very informative on the specific tools. one thing I'd like to mention, did your try to insert the bearing extractor on from the back side first? That makes the most sense to me. Unless of course the closed end of the extractor is to wide to fit through the bearing.
I was thinking the exact same thing.
I will have to double check when I get home. I remember thinking the same thing, but I saw in a different video someone assembling it the way I did in this video, so I went with it that way. I will make sure though and report back!
Recently bought a $12 BB from ebay just for the cups and put 6805 Acer racing Ceramics in. I have about $62 in a super fast smooth BB.
Removing the chain is KEY!! Thanks for the video, just did this last week, i should found your video before, tho... :)
I'm glad it helped! Yeah, removing the chain definitely helps you isolate the noises!
I just lift it off of the ring and crank. On a 1x there is no need to separate it.
Thanks for the great video, do you have a link to the bearings? I want to try this but not sure which NSK bearings to use
These are the ones I used: amzn.to/4eSwsz7
@@UmunhumCycleworks Thanks, I found them in 6806 VV instead of DD. Not sure if there is a difference. Hope they work.
So basically I can put super quality bearings into my 17.00 SHimano Deore BB. Spending much less money then upgrading to Chris King BB. Curious, where did you purchase your bearings from?
Yup, 100%! As long as they are the correct size, you can put whatever bearings you want. I got mine from a reputable seller on eBay, but I've had good luck with orders from Roda Victoria if you're in the USA.
Great content. What are the bearing specs for Shimano BSA?
BSA is the type of thread and has nothing to do with the bearings. Shimano has a few bottombracket types: square taper, octalink and hollowtech 2.
Nobody tell him his chainring is wobbly. (joke).
Kids: DANGER: He's a pusher! Just say No.
Don't go ceramic bearing on your bottom bracket. They are not an upgrade. The ceramic balls will dink the races of the bearing very quickly due to lack of elasticity in them and will run rough rather quickly. Ceramic bearings where invented for high rotational speeds and not for irregular loads.
to much tool for simple removing BB bearings, and as usuall preparation is most expensive
Sadly road BBs are different and not easy to rebuild 🙁
Thumbs up for buying the press from an American company and not cheap Chinese crap. Sorry CCP, no money for you here!
