Bb386

[ljm]

Hi,

Is anybody using BB386 shells? If so, are you making them yourselves, or are they available off the shelf?

Cheers,

Lawrence

Do they realize the irony in this statement?

"There have always been many standards of BB in the market. Those of us old enough will remember French threading, Swiss threading, as well as English and Italian. The Bike market follows trends that continue innovation. As opportunities arise to really improve performance, or adaptability, we believe the industry will adopt them, provided they make sense. Thanks to this new standard, cross platform adaptability, lighter weight, and increased BB surface area can now be had with one system."

It never ceases to amaze that anything with a bearing and thread in a bicycle just lasts

However simplifying it to press fitting a bearing and it becomes a clusterfuck of incorrect tolerances and shiity manufacturing to save a buck

No irony meant at all; I'm simply curious as to the take up of this particular 'standard' amongst custom/low volume builders, as the use of press fit systems does appear to be increasing in this sector of the market. Putting aside the real world experience and concerns of some, I like the concept and (perhaps superficial) simplicity of the various press fit systems.

The debate surrounding the pros and cons of all the solutions will no doubt continue for some time to come. But I didn't intend to spark another run through, only to find out what those who are using press fit are doing!

Nonetheless, thanks for the reality check

The bicycle industry likes it's standards to include multiple choices.
Viva Whitworth!

It amazes me how well marketing guys can make a change (whose main benefit is reduction of cost in large volume manufacturers) into a must have improvement.

These marketing guys are pissing on your back and telling you its raining.

You think they could pour piss out of a boot if the directions were printed on the heel?

I believe they could sell knuckleheads "Boot Piss" as the next big performance enhancer. Remember NEW=BETTER

Has to be said that there was hardly any frame-prep tools, and copper Grease wasn't in fashion for the bike industry in those days...

We had a full Campy tool kit and knew all about anti-sieze, actually.
…..At least here in AZ…..

Ah! I do remember all those bloody Fisher PF bearings being put with no f**king grease at all! What a pain!!

Well, all the rust and moisture had to have somewhere to go, and it always went down.
Some of the removals on those old MTB's were truly epic.
Breaking hammer handles and shit.

Somebody, and I think it was WTB/Cunningham had the foresight so do sealed press fit but with tiny zircs on the top of the BB shell - genius.

I wonder why in the evolution of bottom brackets no one ever used something like a headset with press in cups. Or did someone and I have simply never seen such a thing?

PF bottom brackets are a very similar concept to a ZS headset.
Unfortunately a BB is subject to very different forces in type and direction, hence you cannot use taper-fit bearings like in most headsets.

Yes, I would not be surprised it they wouldn't "walk" in a frame.

So just to clarify, do we like press fit here??...
