Threadless bottom brackets

Please, someone tell me a happy story about using a threadless bottom bracket. Has it worked for you?

All the ones used in the '80s worked great. Klein, Merlin, Gary Fisher, etc.

Once upon a time, a newbie cyclist named DanBraden was trying to track down a "creak" and a "pop" that was living inside of his bike named Horse-Feathers.

He tightened his post, he tightened his seat, he tightened his headset he tightened his feet!
But no matter how many nano-newtons he applied that "creak" and that "pop" continued to hide!
"I know" he said on one sunny day, "I'll swap out the wheels to chase it away!"
So feeling so smart and feeling so clever, he swapped out the wheels on the bike he called "Feathers"
But what would then happen? You should already know, but that "pop" and that "creak" they refused to go!

So back to the board did DanBraden go. What could he do? Well, what did he know?
Nothing was good, and nothing had worked and more and more he found himself irked!
"My fingers are greasy, my knuckles are sore, my pockets are empty, and I've hit the floor"
"I know" he said in a moment of clarity, "To the internet I'll go once I muster temerity!"
So off he went in search of a clue, but to get some respect he had to pay dues.
He was goaded and chided by all he encountered and he delighted the trolls with the tales of his flounder...
"A Flounder" you say, "Do you mean the fish?" There is SOMETHING that smells, but it’s certainly not this!

Then like a light at the end of a tunnel, He read that the BB was where his efforts should funnel.
"At last" he said all full of hope, "I had nearly reached the end of my rope!"
"I'll take it apart, all the way to the BB and find those darn noises which so far elude me!"
But saying and doing are two different things, and poor DanBraden would learn just what that would mean.
For once he removed all that he could, he was stuck with a BB that seemed frozen for good!
So he hammered and cursed, and he cursed and he hammered till finally he settled on one special spanner.
The spanner, you see, turned out to be key for it had special little teeth which aligned perfectly.
So with one mighty grunt and a spray of hot metal, off came the cups with which he intended to meddle.

It was then that DanBraden learned an important lesson; you oughtn’t be messin with what you've been messin...
But in for a penny and in for pound, DanBraden would drive out those horrible sounds.
So another BB did Danbraden order, one that was nicer and made him much poorer.
And when it arrived he marveled at its beauty, "How can I install this without getting screwy?"
Then he remembered how much he had hated that "creak" and that "pop" and how they had grated.
So he wrenched and the kirfed, and he kirfed and he wrenched till finally that BB went in like a cinch!
On went the cranks, and on went chain, and back he put Feathers together again!

And Lo and Behold, but what do you think?
That "pop" and that "creak" away they did slink!

THE END

The moral of the story? F bottom brackets...F them in the A

I "fixed" mine by added a threaded insert that joins the two cups together inside the BB. It was not what I normally like to pay for bottom brackets.

Zero problems with Enduro Torqtite or Praxis bottom brackets in pressfit frames.

They are stupid simple and take minutes to install.

People do get to happy with threadless BBs.

It just takes more time, money, and headache than threaded.

I know, as a BB30 user. It took two years to quiet it, and even now that itís doing fine, I still hate it for all the reasons.

I wasn't too impressed with the Edco "Grip" threadless cartridge. This unit uses eccentric cups to lock the cartridge in place. A clever idea, in principle, and it allows a wide range of chainline adjustment. Itt worked well for most of a season, but the problem I ran into was that in cold weather, the aluminum cups shrank more than the steel shell, and the cartridge would come loose in the frame.

I had been using it in a frame with no useable bottom bracket threads. I ended up getting the Bicycle Research bottom bracket reamer/Italian tap set and cut Italian threads into the shell. It's been fine ever since.

Well...1) I learned about a first-rate company named Praxis, and 2) Then discovered that Wheels Mfg makes the same thing in the color red. And that's pretty much all the happiness I've gotten from press-fit bottom brackets.

I have around 5k miles on my pf30, and so far no problems at all. I do know at some point, probably sooner than later, that'll change, and when it does, I'm going with a Praxis or something similar.

I like working on bikes, but not enough to keep troubleshooting something like that, assuming I don't get it quite right the first time.

I just serviced the bottom bracket pressed in bearings on my new to me 1992 Merlin Road Ti. It has two tiny grease zerks that make it pretty easy.
The bike maybe had 250 miles on it when I bought it from its original owner. I used a Park fine point tipped grease gun, pummped grease
into the tiny zerks and by pumping the gun three times simply pushed the old grease out of the bearing. I used white lighting as it is a clear grease. Once I saw clear white lightening I knew that the old grease had been pushed out. The 1992 Merlin owners manual says grease the BB every thousand miles.
This was the first service BB service since 1992. I have traded emails with Tom Kellogg at Spectrum Cycles and he said they would be happy to install sealed bearings if I decided thatís what I wanted to do. Servicing the BB is pretty easy. Since the bike has so little miles on it...I may just keep it as is.

a few pics- the bottom pic..service cleaned up and done.

Thanks so much everyone. It's given me some hope and some other options as far as threadless BBs down the road.

Just about the only good thing about a press fit BB is that Praxis and the like work very well and don't cost very much. In other words, the solution is to introduce threaded interfaces into the situation. The irony.
