Are Ceramic Bearings Worth It? What the Latest Research Says

In the world of performance cycling, ceramic bearings are often marketed as a must-have upgrade for riders seeking maximum speed and efficiency. From bottom brackets to jockey wheels and especially in wheel hubs, ceramic bearings are touted as the key to reducing friction and gaining precious watts.

But are ceramic bearings truly worth the investment? Or is their reputation fueled more by marketing than measurable performance? Let’s dive into the real science, benefits, limitations, and whether ceramic bearings make sense for you in 2025.

What Are Ceramic Bearings?

Ceramic bearings use balls made of advanced ceramic materials, usually silicon nitride (Si₃N₄), instead of traditional steel balls.

Key Differences:

Harder and smoother than steel

Lighter weight

Lower friction coefficient

Better heat resistance

Higher price point

Claimed Benefits of Ceramic Bearings

1. Lower Rolling Resistance

Lab tests consistently show that ceramic bearings create less friction compared to steel, particularly at very high speeds or in controlled conditions.

2. Weight Savings

Although minimal (often just a few grams per hub), ceramic bearings are lighter, which can appeal to riders chasing marginal gains.

3. Better Durability (If Maintained Properly)

When combined with high-quality races and seals, ceramic bearings can offer longer service life because they resist corrosion and wear better than steel under ideal conditions.

What the Latest Research Shows

Recent studies from independent sources, including bicycle power efficiency labs and professional cycling teams, suggest the following:

Real-World Watt Savings:

On average, 1-2 watt reduction per hub or bottom bracket upgrade.

Complete ceramic bearing setups (wheels, bottom bracket, jockey wheels) may save 4-8 watts total at high speeds.

Diminishing Returns:

Most benefits appear at speeds above 40 km/h.

For everyday riders cruising at 25-30 km/h, the watt savings are present but minimal and likely unnoticeable without a power meter.

Maintenance Is Critical:

Ceramic bearings require more frequent cleaning and lubrication.

Poor maintenance can cause them to wear faster or even perform worse than properly serviced steel bearings.

Not All Ceramic Bearings Are Equal:

Low-quality ceramic bearings often underperform premium steel bearings.

Manufacturing precision, seal design, and lubrication matter just as much as material choice.

Are Ceramic Bearings Worth It? Pros and Cons

Pros	Cons
Lower rolling resistance	Significantly more expensive
Potential watt savings at high speeds	Requires meticulous maintenance
Lightweight	Low benefits for casual riders
Premium race-ready feel	Performance depends heavily on bearing quality

When Ceramic Bearings Make Sense

Recommended for:

Racers, time trialists, and triathletes are looking for every watt advantage.

Riders who frequently exceed 40 km/h average speeds.

Cyclists who enjoy frequent bike maintenance and can keep ceramic systems properly cleaned and lubricated.

Those who ride in dry, controlled environments (ceramic bearings are less suited for wet, muddy conditions unless extremely well-sealed).

Not ideal for:

Casual road cyclists or weekend riders.

Gravel or adventure cyclists are regularly exposed to mud and dirt.

Riders who prefer low-maintenance setups.

Superteam’s Perspective on Ceramic Bearings

At Superteam, we offer ceramic bearing upgrades on select carbon wheelsets for riders who demand race-ready responsiveness and minimal rolling resistance.

However, we’re also clear with our customers:
Ceramic bearings offer measurable but modest gains that are most valuable to competitive cyclists. For many riders, investing in aerodynamic wheels, correct tire pressures, and tubeless setups will deliver more noticeable speed improvements than ceramic hubs alone.

Final Thoughts

Are ceramic bearings worth it?

Yes, if you are chasing every performance detail and can commit to proper maintenance.

Probably not, if you prioritize reliability, affordability, and ride primarily at moderate speeds.

Ceramic bearings are a tool, not a magic bullet. For the right rider, they offer an edge. For most, high-quality steel bearings provide excellent performance with less hassle.

If you’re considering a ceramic upgrade, make sure to invest in genuine, precision-made bearings from trusted sources to truly feel the difference.
