Intersting that its talked so much about the roundness and tolerances, when in fact for any reasonable modern bearing in speeds that you find in bikes, the type of sealing and type of grease have greater impact of power loss than the roundness of the balls.

[@Retardinspector]

at 04:20 he fucked up the measurement by factor 10. how is this a good job?

[@sadlfjasdfacv]

SRAM, Shimano, Campagnolo and FSA are all very competitive companies with very smart engineers. If over-sided pulleys/jocky wheels and really expensive ceramic bearings actually offered real improvements, one of those companies would have started putting them on their derailleurs years ago. Food for thought, shimano doesn't give their engineers any budget limitations when working on new Dura Ace components, and they haven't switched. My guess is they know something ceramic speed doesn't.

[@drownthedays]

[@atiroocky]

In cycling, a good metal bearing (NTN) is as efficient and as ceramic bearings for 20% of the cost. To get the advantage of Ceramic bearings, you need very high rotational speed (20000rpm).

[@Baigle1]

stock bearings, ceramics are lower friction, they almost equal out if you remove the grease and guard. done differently, like matching raceway cage and bearing materials, i think ceramic would win. you can also use other ceramics beside silicon nitride, which has some drawbacks versus competing materials.

[@ivanteo1973]

@@Baigle1 I think you are confused with smoothness and friction. Hardness is the resistance to indentation and has totally nothing to do with friction. that said having a ceramic ball bearing with a steel outer and inner ring is a complete nonsense because the balls will wear off the rings much earlier.

[@Baigle1]

@@ivanteo1973 Now, how do we make it a more efficient sealed air bearing with low friction and no contaminant ingress? Is there a geometry that allows us to use an air journal bearing at high pneumatic pressure, or a low viscosity fluid as the main load bearing material between the raceways, with the ball bearings a failback? How do we keep the balls separate and uniform between the raceways without using a cage and lubricant that adds friction?

[@MntRprznt]

Ceramic bb's might be good in high RPM engines, because of the heat they can withstand, but in bikes, they are not worth your buck. Good steel bearings [like german, or japanese, but not chinese!] are just as fast, and not like the wall presentation in the factory - much slower - that was bs. Ceramic are bit lighter - thats all. Not worth your money, but nice ad.

[@briantruck2284]

True

[@D.Eldon_]

Some drivetrain component manufacturers switched to ceramic bearings years ago. For example, SRAM has been using ceramic bearings in its top-of-the-line Red bottom brackets (such as the Red GXP that I prefer) for quite a few years. They say the bearings come from a "BlackBox" Danish source. Is this CeramicSpeed? I don't know. SRAM has also used ceramic bearings in the jockey wheels of their Red rear derailleur for years (this goes back to their 10-speed derailleurs). Perhaps that's why CeramicSpeed reports a smaller increase in performance of the SRAM version of their oversize OPSW cage and jockey wheels compared to Shimano. I don't believe that Shimano has made the transition to ceramic bearings yet for Dura-Ace and I'm not familiar with other drivetrain manufacturers like Campagnolo, FSA, Rotor, etc. Another source for GXP bottom brackets that I like is HSC out of Melbourne, Australia. They use grade 3 ceramic balls the same as CeramicSpeed yet their bottom brackets cost $127 in the U.S. versus $359 for the uncoated CeramicSpeed version (the coated CS version is $499). One of the biggest surprises for cyclists inexperienced with ceramic bearings is their frequent service requirement. If the bearings are harder and wear longer than steel, why is this so? Answer: Because the races are still steel -- only the balls are ceramic. This presents a problem when the grease is contaminated because the much-harder ceramic balls will quickly score the softer steel races. Plus, ceramic bearings tend to have less weather-resistant seals. Why? Because the better the seal, the more friction it adds to the bearing and, since the primary purpose for ceramic bearings is reduced friction, the seals must be fairly light. These lighter seals mean that the grease in ceramic bearings will usually be more easily contaminated than all-steel bearings with better seals. So manufacturers like SRAM recommend that ceramic bearings be cleaned and regreased immediately after every exposure to rain or foul weather. Failure to do this will cause the expensive bearings to degrade faster than all-steel bearings. However, if the ceramic bearings are never exposed to rain or bad weather, their service interval is just as good, if not better, than all-steel bearings. One of CeramicSpeed's optional features is a secret metallic coating to both the inner and outer steel races which is supposed to increase their hardness by about 75% (they claim). This may mitigate some of the contamination problem above and extend the bad-weather service intervals. But the coating adds about US$140 to the cost of a CeramicSpeed bottom bracket or US$100 to the cost of a jockey wheel set. I can buy about four HSC ceramic bottom brackets for the price of one coated CeramicSpeed BB so I think HSC offers a much better value. And, like CeramicSpeed, HSC can claim that world champions use their products, too. I like what CeramicSpeed and their competitors are doing and I think it definitely makes sense for athletes chasing a win or world record. I'm willing to pay a little extra for ceramic bearings as long as it isn't too much extra. Regretfully, CeramicSpeed is too much for my budget. However, I doubt that ceramic bearings make sense for most non-professional cyclists because of the expense. You can easily spend more on CeramicSpeed upgrades than you would buying a new mid-grade road bike!!! If you service your all-steel bearings regularly as recommended, they should last plenty long. And the few extra calories you'll burn pumping out a few extra watts will probably be good for your health. :-)

[@happydays8171]

If I'm not mistaken, CeramicSpeed coats their races with a titanium film that gives them the strength mentioned. I thought all CS races had this coating, but you're saying it's extra?

[@grvl307]

2 friends of mine have had these jockey wheels disintegrate causing the rear derailleur to go into their wheel. They both were very lucky as this could have taken out a large groups of riders at high speed. They've heard of this happening to others as well. Needless to say they no longer use these

[@wubble666]

I have seen a couple of poorly installed cages that have done this. User error every time, generally cause by not following the instructions and taking their time with maintenance.

[@dannyhanny1191]

I'm most certainly not going to state they were as high in quality, but in the 2000's jockey wheels with bearings were being sold, and their life-spans just weren't as good as OEM jockey wheels. Either due to bad weather riding, or just use, the bearings would start to seize. We all gave up on them then, so I can certainly understand how it would happen now. If CermaicSpeed really is using looser seals to 'market' the watts saved, they would allow more road debris into the bearings.

[@RomansFiveDotEight]

Here I was thinking they were so expensive because of the materials they use. Turns out, it's because the guy who puts the screws in is a pro cyclist! I bet they've got Eddy Mercx in the back running the CNC machine!

I respect quality over quantity but hopefully now you can understand Romans point.

Interesting video, but some snake-oil alarm bells are ringing. For professional use the races also have to be made of ceramic. Only then i can turn my headset at 12000rpm nearly frictionless. To make your cranks spin like in the video, remove your sealing and ungrease your cheap bearings.

[@jamesrindley6215]

This is a cool technology but the demo of the smoothly swinging crank looks fake. Take a clean well-adjusted steel ball bearing without seals and it'll swing freely just the same. I've seen this even with cheap bearings. So yeah, ceramic bearings might have some advantage but this company should be using honest demos of comparing like for like. Otherwise it busts their credibility and leads to doubt of everything they claim.

[@Baigle1]

good job you got em.

[@NielsHeldens]

I have to say that this appears to be one _smooth_ video

[@gcn]

😂

[@echtogammut]

I've been using ceramic bearing for a number of years in various implementations. For bicycle applications they are not substantively different from precision steel bearings and the spin of unloaded bearings is a useless demo of their function versus a steel bearing (although I love doing it). Ceramic Speeds jockey wheels and lube arguably have a far greater reduction in driveline friction compared to using ceramic versus NTN non-contact steel bearings in a similar arrangement. This largely comes down to the seal and lubes used in the bearings and has little to nothing to do with bearing durometer or precision (the measurable difference between NTN and CeramicSpeed is for practical purposes naught). For someone who is obsessed with freeing watts, your best bet is to research grease and to use low friction seals on your bearings as that compromises 80%+ of bearing friction. I'm not a naysayer of CeramicSpeed, but there is a lot more marketing fluff than actual engineering science in a lot of their bike shop presentations. I personally use their products, but I also know that the gains versus precision steel is within most margins of error.

[@dannyhanny1191]

[@reginaldscot165]

In fact in testing I have seen the high quality steel bearings are marginally better and last longer. And if you look at the price for Ceramic... ouch

[@jeffr119]

Correction: at approximately 4:20 in the video you stated that the tolerance on the bearings was "2.5 microns, or 0.00025". That is incorrect. 2.5 microns = 0.0025: you were off by a factor of ten. If the tolerance really is 0.00025 then that would be 0.25 microns.

And as a bike Mechanic I have taken enough Ceramic Speed bearings out of bikes to know they don't last all that Long. Certainly not long enough to justify them being 10x more expensive than steel bearings. You see the hard Ceramic balls chip when hit and the ball hardness leads to them wearing out the steel races faster.

DA pedals must have CS bearings, they're soo smooth...

[@LarryGottschalk]

Very nice. Would be nice to speak to some of the people though!

I just can't justify paying $479 USD for a ceramic BB with coated bearings. I'm sure CeramicSpeed BBs are good, but they cost at least double what they should.

Did they mention what type of machine specifically they used to create the 3D printed jockey wheels? Powder bed, Direct energy deposition, etc.?

Ok, here's the script for today's show, Lloydy. Dan [complete deadpan]: "pretty excited about today..."

Nice chain keeper at 10:05 :)

Here's a caveat about Ceramic Speed BB bearings, if your BB shell isn't created to the same precision as the bearings you don't gain any benefit.

Hello! Can anyone help met about oversized pulley? I use 50t chainring and 23t cassette,what sized of oversized pulley i will use?

[@PatMeurier]

use bearings that have metal cages and non contact seals, just as fast, last way longer and much cheaper. check out hambini he tests the life span of bottom brackets and Ceramic speed won't submit one for test.

They won’t dare send him one because he would eat their pseudo science up for lunch and they know it. Con artist products like this that are backed by non scientific con artist claims can only survive if they maintain a pool of gullible fools to sell their snake oil wares to. That pretty much sums up their ceramic bearing customer base at this point. As PT Barnum used to say, “there’s a sucker born every minute”!! 😃

"So what are we doing today?" "Proving that sand, grime, and dirt makes the bike go slower" "We already know that" "But have you PROVEN it?"

THE LOVELY LADIES WORKING THOSE BEARINGS!!!

[@scottishjohn]

Can we say that the best part of the tour is Dan's strong hair game?! No but seriously it was Dan's hair... Actually I think just seeing what the bearings are made of and looking at the hall with the very real world comparison of what a difference a good low friction bearing can do does bring it into contrast. Wish that the jockey wheels didn't look so hidious otherwise they would be a very appealing prospect!

We'll pass on the compliments to Dan's hairdresser.

I fell for it in my early riding days - have a ceramicspeed bottom bracket, but after watching hambini NTN non contact seals for any future bearings …. Unless I make it into a Tour de France team, then 🙄
