world of ceramics

[ada@prorider.or]

i did a calc for a pro
what the ceramics bearings would do

this is what i found out

i took the same parameters for all calc the same except the watts

if a certain rider did
time trail 10 km at 400 watt on flat road
he did 11.29 with 399 watts he did 11.30

on a climbs 10 % with 399 watt 34.45
400 watts 34.41

remark as lower the watts is generate by the rider the bigger the cap

Did you test whether ceramic hybrid bearings offer the same advantage? What type of bearings are you using for the comparison? Cone and cup or cartridge bearings?

Thanks for the information,

Thanks for the information,

hybrid bearings advantage are smaller
comparison is to a nomal cardrige bearing in optimum condtions
and weight load 100 kg ar 400 watts at 80 rpms
and wheel speed 50 km/h n 379 min-1
normal bearings with grease


and gain 1 watt is for total drive train

and gain 1 watt is for total drive train

Total drivetrain = ?

I assume you mean:
BB
rear mech jockey wheels
both hubs
pedals?

Was the rear hub a 4 bearing setup?

Thanks for sharing your research with us.
