Sure, the races are the parts that can get pitted if they are not hard enough, which is why they are NOT made of aluminum.

SquidPuppet

Yeah yeah yeah. I was reading their site out of curiosity to see how they justified the price, thinking maybe I'd learn or discover something. The lack of specs made me curious, so I called. It was a 3 minute event, not something I obsessed over.

SquidPuppet

LMFAO. The bottom cup and crown race support all the front weight. The bottom cup is where the brinelling takes place, not the race. The bottom cup is aluminum.

Take a minute away from trying to prove everyone wrong, and spend a moment reading about brinelling. It's what causes the sticky indexing feeling in a headset.

TejanoTrackie 

Well, you clearly are clueless on this one, so I'll just let you wallow in your ignorance.

SquidPuppet

Right. Just like Ashtabula was NOT a brand. We learned how "correct" you were on that one, eh?

So, Mr. condescending, why not explain what I have wrong? A pitting vs brinelling conversation will certainly expose your lack of knowledge.

Perhaps you'd get off your high horse and listen if Sheldon Brown were talking.

And that ^ is why I cared about the hardness.

That first blow to the chin is SOLID.

@TejanoTrackie i read that an airport in FL recorded a temp of 139º today, while us chumps up here are freezing our rocks off in the snow getting snowed on

super jealous of basically anyone living anywhere else this week

TejanoTrackie 

First off sweety, you need to take your midol and unbunch your panties. I just happen to know what brinelling is all about, as I specified bearings for machinery that I engineered in my business.

What you fail to realize is that Sheldon Brown was talking about steel cups, which have the bearing races machined directly into them, whereas aluminum cups need to have steel inserts to provide the bearing surface. Also, in the case of cartridge bearings, the races are integral to the bearings, and the cups themselves do not experience any direct contact with the bearings, nor does the so called fork crown race, which is merely a base for the cartridge.

So, again I'll state the fact that the hardness of the aluminum cup material is irrelevant to the proper design of a headset, as I'm sure the CK rep could have told you had you'd given him a chance.

TejanoTrackie 

Yeah, this was just a very good day down here today, and is well above normal, so I'm just lucky to be able to take advantage of it while it's available.

Scrodzilla

So much "Oh snap" was just served up hot & fresh. Free delivery too!

SquidPuppet

Really? Tell that to FSA. They use an angled, exposed needle instead of a ball. And their cups do NOT have a steel insert. Their crown races are aluminum too. At least on the Orbit series.

What companies have a steel insert in their aluminum cups?

It does if the balls or needles come in contact, as does FSA's.


LOL.

I am in Bogalusa, LA this week. When I stepped out of the factory for lunch, it felt like it was 80, the sunshine was awesome too.

Abita Springs brewery (makers of Turbo Dog and Purple Haze) is close to here. That would be a great ride.

SquidPuppet

Not quite.

TejanoTrackie 

All irrelevant hogwash, as CK uses cartridge bearings. But since you asked, I have an old Stronglite threaded headset with aluminum cups and needle bearings, and it still has steel inserts for the race surfaces. Needle bearings are far less susceptible to brinelling, as they provide a line instead of point contact that balls make, which reduces the stress, however, it still seems foolish to use aluminum as apparently FSA does. The problem with needle bearings is that they are extremely difficult to adjust, which is why most manufacturers prefer to use ball bearings for headsets.

Mumonkan

uhh, my orbit headset has sealed caartridge bearings. jussayin.

i also have a headset thats 27 years old with caged bearings on a steel race and there is no brinelling

Huffandstuff

All of this CK talk has inspired me to buy one for my #kilott .

LouCypher

fuggg I need to sell off all my assets and get the **** out of these winter states.

TejanoTrackie 

But dude, they refuse to divulge the material specs for their headset cups.

Flatulentfox

I have two fsa pigs. They are headsets. They have steel in them.

hairnet

They're pigs because they are steel. I dont know why but I have one on my Surly.


Today I got a bit closer to mastering this overhead welding thing. No globs of molten metal raining down on me or some ****.

Flatulentfox

I really need to learn to weld.
Would be a. Good skill to have
You learning for fun or for work opportunities?

hairnet

Training for certifications.

Huffandstuff

Looking good, just remember to always wear ear plugs when welding overhead otherwise your day might get a whole lot worse.

Yeah, but at least I can have a sweet purple headset.

TejanoTrackie 

Haha. You've definitely got your priorities correct.
