I've replaced cartridge bearings on a couple of Race Face BBs that specifically said "do not disassemble" on them and have had no issues. That said, BBs are pretty inexpensive so the savings may not be worth it. I just hate to see thins get thrown away.

 

do you know what bearing size is used? what type of BB was it?

thx

I don't use Dub but I replace bearings when I can because i can usually buy superior quality ss bearings than what comes with the bb.

 

A DUB BSA 73 is like $15 from Jenson right now, is it really worth the time/cost to replace the bearings instead of just changing out the entire assembly

FWIW, I just regreased my original DUB BB after 3k hard miles, the bearings are still smooth, the key is to not wash your bike often and be careful with where you're spraying the water...

You own 3 bikes, been a member here for 2 decades, but you're just now starting to work on your own bikes, I guess it's better late than never, good for you...

+1 for the DUB BB - Same here with over 3K miles, smooth as the day I got the bike and I do wash often, showing the bike, not spraying hard stream.

 

I run Wheels Mfg BB on all of my bikes, simply replace the bearings when needed.

 

Why not service the bearings and extend their service life?
Are they trashed now?

 

Depends on bearing availability, but if you know your bearing specs replacing bearings for bb30 saves you a little bit you can get better bearings, dub and shimano BBs are so cheap and reliable its easier to just replace

 

I yielded to consumer economics and just keep a ‘ceramic’ 24mm BB generic on the shelf. Whenever a BB fails, the swap takes 10 min, and I order another one slow boat for $15.
They seem to last about a year or a race season.
Same as the Saint, XT, the Deore\basic and the sun tour. Better than the non ceramic generics.

 

I have a ceramic Wheels Manufacturing BB on a Tallboy with about 12 K on them. Well maintained.

 

I replace the bearings. It's inexpensive. I ride in dry conditions so I replace when I burn them out. They're past maintenance.

 

This is why I'm running my 30mm spindle cranks for as long as I can, because the 6806 bearings are so easy to come by, vs. dumbshit Dub or that new smaller Shimano standard.

 

99% of the time it will be easier and cheaper to replace the BB. Instead of cheaper, I should say close enough to not be worth dealign with bearing replacement.

 

 

Actually, been a member since the beginning ...maybe 1999? ...but went inactive for a few years and they purged my account.

As mention, I used to work on my bikes and all my friends bikes too starting around 1986. I got too busy travelng for work in the mid 1990's and wanted to come home to working bikes plus the shop I rode for worked on my bikes for free. When you have professionals working on your bikes, it's hard to justify buying all new tools to meet the ever-changing standards, but thanks for the judgement! You might want to check your reading comprehension (and your aditude) as I didn't say, "I have 3 bikes" either.

Before I go to busy to work on my own bikes, I used replace the bearings.

With your broken English and grammar, you try to call me out on my reading comprehension 🙄

I just started working on my own bikes, so newby questions.

Which I took as you haven't work on them before, my bad, I should have known that meant "I used to work on my bikes and all my friends bikes too" 🙄

You might want to check your reading comprehension (and your aditude) as I didn't say, "I have 3 bikes" either.

My question is relative to DUB BSA 73 because at least three of my bikes use that standard

I read "three of my bikes" yet I need to check my reading comprehension 🙄

BTW, I provided info about my experience with the DUB BB as well as the current cost of one, a thanks would have been more appropriate rather than your negative comment toward me. I'm not a mind reader where I know what you were thinking but didn't actually write it down, dude, closely reread what you wrote in your initial post
Adding you to my ignore list for your negative attitude when another member provides constructive feedback to your thread 🖕

 

OP here, wound up just going with a SRAM BB mostly due to price. The cost of a suitable torque wrench plus some bits was 3x the price of the actual BB.

 

Did you not already have a torque wrench?
I'm not clear on how this fits into the BB equation?
