Be sure to check out abbottracing.org for more triathlon related content.
Are the marketing claims about the benefits of low friction bottom brackets real or BS? And if they are real, should you actually buy one?
For the TLDR, skip to 5:54
I pulled data from Friction Facts, Best Bike Split, Zwift testing, and a host of other sources to try and answer just that.

An interesting 3rd option is to buy normal industrial steel bearings and give them thin oil like ceramic speed and no seal to reduce friction on race day. Ceramic bearings have more friction after 1000-2000km compared to high end steel bearings.

"Ceramic bearings have more friction after 1000-2000km compared to high end steel bearings." Why? Is this confirmed and tested? Thanks

I got a new bb few days ago. I asked the owner whats his opinion about a ceramic bb. He said you have to pay for it go for a standard bb, if sombody else is paying for it go for ceramic bb. He also said you have to service your ceramic bb more often. I ride in all conditions and the standard bb has better seals in it.

I bought a expensive Ceramic Speed bottom bracket and after about 500 miles it started to creak. After 1.5 k miles I took the crank off to inspect and there was some black substance around the bearings. I took the seals off the bearings and it looked like the bearings were disintegrating and they were very loose but still rolled smoothly but had a lot off play. Hambini was right when he said ceramic bottom brackets are sht. I put on a Dura Ace one. Rolls nice and I could buy 4 of them for the cost of a high end BB.

Sorry for your bad experience, I assume ceramic speed would issue a warranty for a bb failure with such a low milage. But you are correct that you can get several DA bb for that price

So I don’t care about the speed. It’s the energy savings over 100+ miles for the same speed I currently do.

Late comment here but as info the manufacturers warranty period is more of a marketing decision by the manufacturer than a fact based statement on life expectancy

I think marginal gains will add up, if you consider the OSPW of your other video it will add up to 5w save that is something

@edt6488 4 күн бұрын

I don't think there is an issue with marginal gains adding up. It's about the cost-benefit relationship. If I pay $100 and get back $1,000, then it's a no-brainer, but the reality is no upgrade is going to give anyone a return in the multiples. I think most people need to think about it a bit more carefully before splurging if the upgrade is only going to make them a few seconds faster over a long distance, especially if they are not racing for podium places.

@pepetelacrosse Ай бұрын

According to your numbers.... if I save 4 secods by investign 1 watt (on the 200 watt example) and assuming we keep it linear I would be saving 400 sec from 200 w vs 300 w. this do not make much sence...

@EricAbbottTri Ай бұрын

Time saving is not a linear relationship. As you get faster it takes an ever increasing amount of power to go slightly fast.

@pepetelacrosse Ай бұрын

@@EricAbbottTri my point exactly... so what you are saying is that the difference of puttin 200 vs 300 in a linear system is 400 sec, but since is not linear for the cuadratic term is much less than that... so, the real ttime difference between a guy putting 200 vs 300 watts is less than 400 sec, lets say 180 which means 3 min diference in a half distance. that dosent make sance....

Neither . Ceramic bearings are useless on bicycles. Ceramic bearings are too brittle . They are great for high speed high temperatures (speeds of 10,000 rpm or more) . Non contact seal steel bearings are a much better idea .

@RB-xv4si Жыл бұрын

If you think about it, it’s pretty stupid to show reduced friction in absolute power, like watts, because that’s based off of a particular power input. Obviously, each person’s power input is different, so it follows that their “watts saved” will be different. It would be much more useful to express the watts lost as a percentage of rider power input. That could be applied to any rider.

@EricAbbottTri Жыл бұрын

Actually, friction is a function of the normal force and velocity. If we assume cadence remains relatively constant and there is not a massive increase in normal force between a low and high power rider then the power needed to overcome the friction of the BB is relatively constant no matter the power input.

@RB-xv4si Жыл бұрын

@@EricAbbottTri yeah, unfortunately that’s a lot of assumptions. I stick with what I know. And what I know is that increased force generated means increased power. And that means increased friction. Less power is less friction. So the watts saved over whatever you’re comparing the ceramic BB to is assuming a particular power. For less power input, you’re saving less power. More power input means you’re saving more power. The only question is, what does the curve of that power savings look like as you increase in power output? Is it a linear increase or is there a curve to it? I don’t think anyone has the data on that. Also, the “watt savings” is derived from an assumption of what a rider is using before the switch to this hybrid ceramic BB.

It's not ultra low friction. It's just ultra crap sealing bearings. You can achieve the same for a fraction of the price by peeling the seals from your bearing cartridges, cleaning the grease and spraying some WD40 in instead.

I PROUDLY spent $19,600.00 on the latest, greatest 100% MADE IN CHINA plastic (carbon) "aero" bike with disc brakes (of course) and upgraded it with "aero" and uber ceramic EVERYTHING...... And it is SO righteously "fast". My entire kit is pure "aero", from top to bottom including my lip balm. I also have some super top secret Russian osmium-trilium grease and chain lube. I am SO "fast" on my new steed as I ride to the espresso bar to hook up with my hipster cycling bros.........
