steel may pretend its slower,more firction..but when push comes to shove with 3000 pounds and all day...the steel is gonna win...and do add some racing grease. no regrets.
for bikes and people on them, great, I do not even like ceramics on brakes or clutch pads...it fails me miserably.
think tractor trailer comparing for your car,more than a bicycle.... and trucks fail the ceramic clutch too...  |
More info on ceramic bearings, It might be biased but semms to make sense
FACT:
Like Stainless Steel ... there are many different levels and grades of purity that you can purchase depending on your level of needs.
Silicon Nitride "Si3N4" base is no different.
North Star Ceramic "Race Specific" Bearings only use the Silicon Nitride "SN101C" formulation.
Under race conditions of excess vibration, shock and side load.
SN101C is "SHATTER PROOF" and any other formulation of Silicon Nitride CAN and WILL BREAK!!!
