All the tests i have seen test new or just broken in bearings and show that one could save somewhere between 5 and 10 watts for a pulley bottom bracket and wheel bearing upgrade of course mostly depending on your current set up as a starting point.
Benefits of ceramic bearings.
To give you some baggage in understanding the benefits of ceramic bearings we will list the positives and warn for a few potholes in selecting the best bearings for your bicycle.
Performance benefits of ceramic bearings high quality bearings save watts.
This atomic co operation yields a very strong attraction force and because of this ceramics offer a series of benefits in comparison to metals.
Hybrid ceramic bearings also offer the benefit of not allowing electrical currents to run through the bearing which allows for prolonged use.
In addition to its better performance and friction reduction ceramic bearings began to be applied in cycling to give a solution to the corrosion problems suffered by metal bearings when they are wetted by rain mud etc.
The majority of the professional peloton advocates the.
Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings.
Ceramic bearings offer many benefits for the racer and the cost to upgrade isn t that bad.
Advantages ceramic microstructures enjoy covalent bonding inherent between non metal elements.
Faster et s and lap times ceramic bearings have 1 10th the friction of steel which means faster et s and lap times.
This means they share electrons.
Durability and peace of mind.
A ceramic bearing is also harder than steel bearings up to 30 which improves durability and they also don t rust so less maintenance should be required.
Leaving energy savings aside there are two other sections where the benefits of ceramic bearings are unquestionable.
They normally have a very high hardness 70 90.
But it does matter.
Specific metallurgy balanced internal tolerances and the all important finish polishing of the race channels the balls run in are crucial factors in the creation of a proper hybrid ceramic bearing that will last such as our ceramitech line of bike bearings.
There has been a lot of coverage and many tests over the past few years on the benefits of ceramic bearings over standard steel bearings.
