CeramicSpeed technology focuses on reducing friction and producing bearings with an unmatched lifetime, meaning that you get to ride faster or save energy. With CeramicSpeed products in your hubs, pulley wheels and bottom bracket, tests show that you’ll save between 6–9 watts, compared to using standard bearings.
How many watts do ceramic bearings save?
According to the bicycle.net report, the manufacturer CeramicSpeed stated that ceramic bearings can offer power savings of between 10 -12 watts and bring heartbeats down by 2 – 5 beats per minute.
Is a ceramic bottom bracket worth it?
The Bottom Line: Quality hybrid ceramic bearings are better than steel bearings in a bicycle bottom bracket application because they have rounder balls for lower resistance, better races for lower resistance, and are grease-efficient in low RPM, low heat environments for lower resistance.
How much faster are ceramic bearings?
He says ceramic bearings are said to be three to five times harder than steel bearings and, as a result, can withstand the force applied to them through chain tension and pedalling for longer.
How much difference does a bottom bracket make?
In addition, the average drag for all of the bottom brackets tested is just 0.77W. In other words, bottom brackets do different significantly drag-wise in terms of percentages but as far as actual watts are concerned, we’re talking relatively small numbers here that most general cyclists aren’t likely to notice.
Do ceramic bearings make a difference?
According to research, a well-made ceramic bearing will roll faster, saving you energy and allowing faster cruising speeds compared to an equivalent steel bearing. This is because the properties of ceramic allow the creation of rounder, smoother bearings.
What is a disadvantage of ceramic bearings?
Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Thermal shock is when the temperature gradient within the material causes a differential expansion, which results in an internal stress. This stress can exceed the strength of the material thus forming a crack.

Which bottom bracket is best?
Best Bike Bottom Bracket [Review] in 2021 Best All Round Bike Bottom Bracket For Cycling. Wheels MFG BB86/92 Shimano Bottom Bracket. Shimano Dura-Ace BB-R9100 Bottom Bracket. Shimano Tourney TX BB-UN100 Cartridge Bottom Bracket 68/122.5mm OEM. Shimano BB-UN55. SRAM GXP Team Bottom Bracket.
Are ceramic bearings better than steel?
Because ceramic bearings are harder than steel bearings, they are more durable, lasting anywhere from five to 20 times longer. Finally, ceramic bearings are lighter, because ceramic is less dense than steel (silicon nitride, for instance, has a 60 percent lower density than steel).
Do pro cyclists use ceramic bearings?
It’s in the professional peloton, a place obsessed with marginal gains, that ceramic bearings have become popular in the past couple of years. And naturally, where pros lead, amateur racers and sportive cyclists follow, keen to take advantage.
Are CeramicSpeed pulleys worth it?
Based on the data, the CeramicSpeed pulley is the most efficient pulley, consuming 0.033 watts/set. The results showed the Shimano Acera as the least efficient pulley of the group, consuming 1.370 watts/set. The difference between the most efficient and least efficient set of pulleys is 1.337 watts.
Are ceramic bearings better skateboard?
Ceramic bearings for skates and skateboards are popular because they are stronger, reduce friction, and last much longer than the typical metal ball bearing. Many companies produce ceramic bearings today and many serious skaters prefer them for the best ride.
Should you upgrade your bottom bracket?
Reasons to go for the upgrade Usually if both chainrings and the bottom bracket are worn out, you might as well upgrade to the new setup rather than buy all the parts for your old unit. Besides getting something that matches the rest of the parts, you’ll know you’re hammering on brand-new crankarms, too.
Does the bottom bracket matter?
The bottom bracket or ‘BB’ is the engine room of your bike’s chainset and one of the two most important bearings on your machine (the other being the headset). A good-quality BB, correctly installed, should serve you with years of trouble-free riding, but bearings can wear out or the BB can become loose.
How important is a good bottom bracket?
As long as the parts connecting them are not as stiff as they should be, all that power is not going to result in maximum acceleration. Bottom bracket stiffness is super important. Moving the bearings as far out as possible will increase stiffness and bearing life.
Why use ceramic wheel bearings?
First, ceramic bearings have lower friction while spinning at high RPM. Their smooth surface and uniform size distributes the load evenly across the balls and doesn’t cause added friction from imperfections on the surface of the balls. This translates into less wattage needed in order to spin the bearing.
Should you lubricate ceramic bearings?
No, full ceramic bearings can be run completely dry. They do not need lubrication to run. Ceramic is non-porous, unlike steel, as a result it is virtually frictionless. Because there is no heat buildup and virtually no friction, full ceramic bearings can be run completely dry.
How long do ceramic wheel bearings last?
The below recommendations are based on using CeramicSpeed All Round blue grease. CeramicSpeed bottom bracket and wheel bearings should be maintained every 5,000-8,000 km or 3,000-5,000 miles. CeramicSpeed headset bearings can be maintained once per year for most riders.
How many watts do carbon wheels save?
The Session’s Carbon Wheels are ready for tubeless and additionally are wider, enhancing this effect further. In a headwind, the profile wheel with the widest tire, saved 9 watts. But as we have already presented here on the Session Blog, the candle effect will save an impressive 20 watts in the cross winds.
Are Kogel bearings worth it?
Kogel sell the highest quality ceramic bearings for the both very low friction and durability. A cheap ceramic bearing is often worse than a decent steel bearing. We carefully selected to offer Kogel bearing upgrades for 3 main reasons.
