I would have expect that by now someone would have commented on the angle of that saddle!! Wow!!

Get some NTN steel bearings instead, nearly exactly the same low friction at a far more reasonable price. Plus they last longer than ceramicspeed BBs. Hambini has talked about this at length, and sells NTN bearings, and NTN equipped bottom brackets for certain press fit BB shell standards.

At my age of 74 when I recently bought new a bike that has ceramic bearings. Minimal gains, I admit, but at the same time these bearings and many other gains in efficiency and weight have allowed me to ride much faster so that at times now I can catch many younger riders. It makes be feel better and probably allows me to ride farther and longer than my old 20 year old bike. I have ridden over 60 plus years and at times do it to release stress. I enjoy the many benefits of this new high tech. I plan on riding many more years.

Agreed! Done! Gonna take my bikes to my mechanic tomorrow for a thorough cleaning.

Super technical explanation cleared up for everyone in the cycling world!!! Thank you !!!

Ceramic wears so fast that they are worse than steel over an average life Best bearing are direct from bearing suppliers, not bike brands

People who know the savings (that you are assuming you will get, because don't forget most carbon BB shells are so badly misaligned that they damage your bearings anyway) and still buy them have more money than intelligence.

Awesome video based on facts & numbers. Thanks a lot!

Brilliant video; very well explained; thank you!

Replaced my 4 yr old Ceramic Speed bearings with NTN bearings (from Hambini). Very pleased with the performance and also the BB tool he provided...no more hammering required as with the Park Tool BB30 tool I replaced.

Great informative video using facts, thank you!

Alex, thanks, great video!

One of the best video series on KZfaq. Because it uses common sense, logic and serious scientific arguments. Always impressing.

Thank You Alex!

NTN steel bearings can outperform most of bike specific brands for bearings. enduro/ceramic speed etc...

Put one in the previous Specialized road bike; it was better than stock. It seemed easier to get to higher cadences. The new road bike came with higher end steal BB bearings and so far so good after 6000 km; never felt like the BB was hampering performance. Best bang for the buck is really good steal bearings with really good bearing races for less than half the price.

👍🏻 the success of Ceramicspeed says a lot about us human beings... everybody knows that these bearings doesn't make a significant advantage - but if our heroes ride them to victory, they must be better! So CS is sponsoring almost every top triathlete and some cycling teams, and than they buy potential obstacles like friction facts - and the costumers have to pay all these costs, which are way more than the designing and production and shipping costs all together. Rather stupid... but it works. So, thumbs up for you to make videos like this one!!!

Totally agree.

From my understanding, how easily the bearings spin when no load in applied is a poor metric. Seeing how many quarters it takes to turn your crankset by the pedal doesn't necessarily have any relation to real life performance. Bearings are designed for use UNDER LOAD.

Price comparison per watt savings: do not forget aero overshoes, that is the least expensive (approx. 5 euro per watt).

Great content as always. Ceramic bearings will need over 5000rpm to produce a material benefit. Speak to any manufacturing engineer and will confirm that. So performance benefit for the avg. weekend warriors NIL. I believe that Ceramic bearings are only a matter of good feel factor or aesthetics factor. For a mid-range bike to spend that £ then its debatable. However for any top of the range bike frame ie. Pinarello F12, Cervelo R5 etc. with top components would anyone opt for the budget option? Aesthetics do matter, and is not a pretentious act to want the best component for the bike you love, if it makes it compatible with the top parts you opted and it makes you feel good too. I would rather "waste" £250 for my next bike to look good and feel happy, rather than drinking 60 drinks x £4 at the pub during the year.

Ceramic speeds new testing now has durace at .159 and ceramic speed at 0.033 only a 0.126 watt saving they now have to use Acera at 1.3 watts to get the better than 1.2w pulley wheel saving. There testing varies massively each time they test graphs appear and disappear on the website all the time. Who in there mind compares a £15 groupset roller jockey wheel to a £ 164 pulley wheels.

really like the ceramic bearing due to the smoother feel when I feel but this can be different with other people ✌🏻

Thanks Coach! Please compare hubs next time.

Interesting , thanks

Another great insight into the gimics / trends coming to a rich market. Big business and profit to be made out of cyclists, it's a flourishing market with participants, some with cash to spare.

Hambini has already disproven the marketing claims of expensive ceramic speed bearings. If you're really hunting for watt savings clean your chain.

17:29 actually even aero overshoe (price $10-$30) will save you 5-7 watt. ceramics is the last place to look for adequate watt savings

the best value for watt upgrade is chain wax...you save money from components lasting longer

ntn and skf , just swapped busted izo (busted = gravel crunchy). skf runs smooth

The next question is, is the bottom bracket of the frame properly aligned ? Hambini said, that even on high end frame, the bearings are not properly aligned. If you have any squequing noise coming from your bottom bracket, the sound means that your are losing watts. I would rather buy every year a new Ultegra BB ,which cost like 12 USD , the buying a super expensive boutique BB. Furthermore you have to maintain the boutique BB a lot, otherwise is not worth the cost.

Oh boy, if Hambini sees this he gonna flip out! NTN SKF FAG cheaper than CC and basically the same friction.

Feel like the question is are ceramicspeed bearings worth the money as compared to something like an enduro ceramic bearing at a fraction of the cost

3:30 next video talk about your left-hand drive bike 😃😁

Great information. Especially useful are those simple friction tests. Thanks!

Brilliant

Would this apply to jockey wheels as well?

I put Ceramic Speed BBs on my Ti roadie and I've been pretty happy with them. It's the first serious BB I've been unable to break within 6 months of riding. ( 220+lb weight, very high torque sprinter). I managed to crack a ball bearing after a year (despite quarterly overhauls) and CS replaced the whole unit without a fuss. My 2 cents

if you want ceramicspeed upgrade, buy socks with ceramicspeed motif, you will get the same upgrade but for less money :D

really cool video.......best to save much watts is make the bottom bracket infront of the front wheel...;-))

What's up with the relatively high frictional loss #'s from Chris King BB's ?

May I know what company use cerbec ceramic bearing?

Not sure about other brands but on Shimano’s pressfit outer seal it says not to disassemble, I did however on my old one to see how it is from the inside. As they suggested, not recommended cause the container and the seal are all plastic and they’ll bend a little and could cause more friction after reassembly. I’m very interested about greases though. On top of the original grease that comes with bearings in BB, Pulleys, Hubs. Is it okay to mix the manufactured or bearings grease with a lighter grease like white lithium sprays? I’ve left some white lithium in a container in a room and it got very dry or extremely viscous kinda like more than grease after 2 weeks time in the summer... I think this is a wrong product to use for bicycle bearings. If anyone knows more about this, I’ll appreciate it.

i got enduro zero for myu hope hubs then i got pair of ceramic speed i put them on back hub zero front and 2 zero now in a the freewheel . i must say its a transforamtion its so east to ride even when i push off the front end lifts. i now have purchased 4x full ceramic from the china man £16 each fully sealed ABEC7 zirconia

Boca Bearings offer full ceramic bearings. What is the lightest lubricant that you could use for this type of bearing?

Besides dirt, noticed sweat do drop into the bearing too

Ceramic bearings only perform better than steel bearings at very high rotation speed (CPS / revolutions per second). These speeds are not possible on race bicycle componentry. Even not the jockey wheels.

your bike is unique! drive side left!

How is 105 smoother than dura ace and ultega?

Since a clean quality lubricant is the most effective improvement to BB performance, what is the best performance lubricant for BB?

Can you explain the saddle angle?

So what bearing is best for mtb?

What about the ceramic bearings for hubs? Are they any better performance wise?

Have you done a best chain topic?

and you get the CS from lots of people they don´t need it because it´s content of a bike frame and they need another size ...

I guess I’m one of the few who has benefitted from a CeramicSpeed BB. That said, I’m an older, non-racer, enthusiast with a few extra bucks, who is also a gadget freak. I installed their PF30 BB about a year ago, and although I did go negligibly faster, I was consistently able to spin 3-5% faster. A big part of the increase was probably due to cleaning the BB, but I regularly clean it every 1500 miles or less, and I only ride on dry, paved roads. So is it worth it? Who knows, but for me it was because my legs weren’t as dead as before. How about a video about using ceramic bearings in pulley wheels (in non-OSPW SYSTEMS), and whether there are any benefits in using 12 tooth narrow-wide wheels over the standard Shimano 11 tooth ones.

I don't think that u're going to be invited to CeramicSpeed's Christmas party.....hahahahahaha

My ceramic speed bb was toast after 4months fair weather riding. Steel this time. I think 🤔

1st ? btw : check hambini channel and then u will see it doesnt matter so much on bearings but on centricity or should i say excentricity of BB frame s hole ....

Any suggestion for ceramic Bottom bracket with good price?

Have you looked at Pinion Gearboxes?

Indeed worth it ceramic speed for Me. If you have money and want to try something different why Not:

Does the heat affect this calculation?

So, basically, do the cheap stuff first. Then, if you have the cash to burn, buy ceramic for the psychological boost it gives you that far exceeds the actual watt savings. However, since most people won't do the cheap stuff like cleaning, they'll buy ceramic bearings which will get dirty and slowly lose their absurdly marginal gains just as quickly as the person who buys $20 steel bearings.

why does and how does your bike have the drivetrain on the other side ?

I have never cleaned my bottom bracket. I did the coin test and it did now move with 9 coins (74 grams) so I filled up a water bottle and used a scale. My pedal arm did not move at 230 gram, WTF! Its going to service on monday. Anybody knows how many watts there is lost in my bottom bracket? Thank you for this video @FastFitnessTips: Cycling Science!

The ceramic balls are too hard and wear out the bearing tracks. So wear over the lifespan of the bearing is poor compared to steel ones.

Cutting through the bullshit. Good man

I have press fit Dura Ace bottom brackets on two bikes for a year now which isn’t advised to clean. It’s of course much smoother than when assembled. I wanted to follow your lead of putting a coin on the crank to check for smoothness. It looks like it needs like 2-3 AA batteries 🔋 to move the crank but when I pedal it with my hand, it looks smooth. Adding force and letting go would spin it like 4 times. INEOS never mentioned using any specific bottom bracket brand so I’m assuming they’re on the same boat. Am I losing many watts in my BB setup? Honestly, Hambini’s £170 is way too much for now...

95% of resistance of rolling bearing comes from grease and seal, few % from cage and rest of balls

my pedals turned with 1 quarter. i guess thats good?

how could shimano 105 steel be better at results than shimano dura ace 9100?

The amount of watts saved would be more dramatic without mtb pedals

This is question for Hambini 🤔

how to prevent contamination

If I have 200 bucks right now, I would spend it at my LBS to service my bike rather than on those fancy balls. Me bike hasn’t had a service for the last 30k Km. 🤔

SRAM GXP steel outperforms some ceramic bearings lol

Shimano 105 has less friction than both the ultegra and dura ace. Not my experience.

Whats up with your saddle in the background? If thats for real, check your fit

No. Go with cheap BB and replace it even twice per season

Hambini, a REAL engineer came to the same conclusion, ceramic is a rip off.... in carbon frames much of the resistance comes from misalignment of the BB...

i love no bullshit, no marketing hype crap people like you who tell the truth. a very high end bike shop here in TO tried to sell me high priced wheel and justified the cost by saying " but they are ceramic bearings ! " asshole ( him, not you of course ! )

Why is the video reversed? I'd think you'd have to try to get it that way. How can you not notice this before publishing the video?

No . Thats it

I think some people with money to spend want to disqualify the equipment as a source of their slowness. This is a mental "game" they play. But it's no game really. It's a practice that makes those who have this need feel comfort. Im one of those guys who feels that some little thing in my drivetrain, the chain, the wheels, the tires, etc may detract from my overall performance. IF, I eliminated all those factors. THEN, I know it's not the BB or whatever that's slowing me down. All of those factors have been eliminated to put my performance or lack of it, squarely on my shoulders, cause now I have no excuse.

Ceramicspeed is definitely an over kill, over rated and over priced product for that marginal gain. We have to use the average cyclist as reference to determine if a product is too expensive for that meagre gain.

No way steel is anywhere near the perceived performance benefits of Ceramic bearings. Ceramic just feels sublime. Even hybrid ceramic feels much better than steel. The caveat is...Most riders are not making a living from Cycling and any gains is not paramount to wining and losing. Fact: Races at mere mortal levels/amateurs are won on fitness. The rest is what you like as an experience from a product. Life’s short. Why the rationalizing. You either can afford it or you cannot.

Roasting time?

Spin test on my old UN26 bottom bracket: kzfaq.info/get/bejne/qr2loqSpt5unops.html

IF YOU RACE VERY LITTLE DIFFERENCE ! IF YOU DONT RACE FORGET IT WASTE OF $ AND TIME !

Second!

That’s a lot of $$$$. I passed.

Ceramic Speed sells snake oil, unfortunately or fortunately for for Cerramic Speed they do a great job of marketing...

man i think you should ride a bike by yourself and compare in time!! when i see your nasty bearings shame on you... how can you ask performance and efficiency if you never clean bearing ... so wtf are your arg. for compare it. for tryed many bearings and riding more than 30k a every year with all climate. trust me they are worth at all. You can do easy maintenance, the bearings dont broke (yes many brands if you ride to long with the bearings they just broke and not beacsue of nasty, only because they get used). for a random guys, dont buy it. only if you clean your bike like me every weeks. or if you ride for competition just buy it. I check bearings every 3000KM and every 700km my bottom bracket is openned for clean everything if there is not rain . riding on rain i just clean every 300Km.

This video is very one-sided ... same like some magazines. If I compare my CS BB bearing to the one of c-bear for example there´s a huge difference. Quality of c-bear is not the same like CS. I don´t know if this guys ever drilled a oversized pulley from CS ... this one just doesn´t stop turning ...
