does anyone know who makes aftermarket bottom brackets for campag ? im after a light ceramic bb that isnt the price of super record

SushiJoe

The bearings are on the cranks. The cups have no bearings in them, thus why they [BB cups] are so cheap. The Super Record ceramics [and Record for that matter] are on the cranks themselves.

From Campy's website re: Super Record Cranks:

"Full-carbon unidirectional-multidirectional cranks - hollow cranks (Ultra-Hollow™ Structure) - light alloy fixing bolts and nuts - light alloy chainrings with ESP Actuation System™ (Enhanced Shifting Performance) - chainrings with hard anodization treatment - 8 pins on the large chainring - CULT™ bearings (Ceramic Ultimate Level Technology) - integrated ULTRA-TORQUE™ semi-axles - requires ULTRA-TORQUE™ BB cups."

thanks, i did not know, its really the only reason i joined the forum to see if i could change from my new chorus to something equivalent to super record, but aftermarket in ceramic and titanium without the price tag.
thanks again

You can get ceramic hybrid bearings that fit Campy UT spindles, but I'm not sure that you can get full ceramic - both races and balls. There is usually a huge difference in price. The ceramic speed bearings pictured appear to have metal races, not ceramic.

The Campy CULT bearings are a unique product that no other company offers. Technically, it's still a hybrid, but with special metal races that are much harder than the product offered by anyone else. Do you have a price for those bearings?

thats great mate, glory cycles looks the go, ill give them a call ! and no i dont have a price for the bearings except for the super record ultra cranks and there around $1000
thank you

I would NOT pay $200 for those bearings. Big price, small benefit. If you wait awhile, I suspect that the SR CULT bearings can be had for less than that. Campy lists the spare part, but it may be too early to find it easily.

Here's a lot cheaper source, but they still seem overpriced.

You're looking at the wrong stores for those cranks. They can be had for $513 from Shiny bikes.

if you do order some bearings, make sure that the shop you go to has the campagnolo bearing removal tool, (it's a pricey one).

unless there's something wrong with the bearings that it came with, (which would be covered under warranty) just leave them on there.

DaveSSS 

Campy does not make a bearing removal tool. Most people use a relatively cheap universal puller.

I feel like my stock 08 Chorus steel bearings spin about as well as anything else I've used (including ceramics), fwiw.

Ceramic bearings are BS...if you are going to ride in all weather conditions it is more economical to replace with steel bearings.

If your existing bearings are not out of tolerance then its not going to make any difference. Zip, zilch, zero nada!

Very appropriate name for ceramic bearings

SushiJoe

Now that you mention it...

Incorrect, ceramic bearing do have a place in performance bicycles just as they do in other fields. For example, if you are a 600 lb rider, and you often ride in temperatures over 500 degrees F, and your bearing are spinning at 5000+ rpm, then they should hold up longer and provide less friction than steel bearings. In fact, at speeds over 20,000 rpm ceramics really shine compared to steel

Here are other ceramic bearing applications that are just like a bicycle bottom bracket:

Aircraft generators
Biotechnology equipment
High speed machining and grinding spindles
high speed mills
Precision instruments
Pumps and compressors

Also, ceramic bearings are lighter, so weigh your steel bearings (1 gram each for .25"), and deduct about 30% to get your equivalent ceramic weight. So a BB, with 18 bearings, will save about 6 grams.

The cult bearings may actually offer an improvment in durability for those who ride in awful conditions. The bearings allegedly need no lube, except to reduce noise. Oil is used rather than nothing. They don't even use seals on the inside.

Other than that, you never see any claims about watts saved do you?

pac819

i checked all the sites and i im going for the total cycling with the bearings and shiny bikes for a full titanium cassette.dropped 80grams in weight as well.thank you all, youve been great

pac819

sorry to bother you about this,
but would you be able to tell me briefly how to put a permanent picture on the threads i post - like the wide angled picture of the bike you have at the bottom of yours ?

Don't expect those Ti cogs to last very long - roughly half the life of steel. Unless you're racing at a high level, it's a waste of money. Unless the racing involves a lot of climbing, still a waste of money.

MONGO!

Homebrew01

TI cassettes must work out to 6+ times as expensive as steel, triple the cost and half the life. If I had one, I'd probably spend my whole ride avoiding the ti cogs, or if I had to use them, feeling the money slowly grind away with each stroke ! At least put the money into something blingy that will last a while.
