???Cermaic bearings (logged +mph used in wheels)???
« on: April 04, 2013, 09:52:10 AM »
Has anyone seen a legit MPH bump using cermaic bearings in their wheels? Bikes or Cars? I assume there are more prevelent in bikes. I know they reduce rolling resistence but was wondering at what MPH it no longer helps or does help.
If You could include wheather it is a bike or car and what about the mph bump was at what Mph.

Greg Neal ran with standards and ceramics in the same year. He keeps good stats. He might be able to help with that one. He posts as "Roadracer".

Also try asking Van Butler, the motorcycle committee chairman.  He built his wife (Cathy's) bikes, and since they used to run small engines I know he used every trick he could find to get MPH.  I assume, therefore, that he'll have information on whether they're of value.  His contact information is in the rulebook.

Well i have mine installed and will be testing them later this month. I am also doing other mods however i can tell a difference in the wheel spin.

gsx-rboy750,

We experienced a tremendous difference after making a pass on the ceramics with how the bike rolled freely when moving it around in the pits. I did the typical spin test as soon as the wheel was reinstalled and it actually did not free spin as much as with the steel bearings but what a difference after a 1 mile run.

We had that discussion here:
http://www.landracing.com/forum/index.php/topic,12257.0.html

I posted a spin down test comparison for different types of bearings.

If you are looking for validation to warrant the high cost, then that chart is the validation.

Looking for end results on the track introduces too many variables. Wind, barometric pressure, differences in tuck, too many things can change run-to-run numbers with zero changes.

We all want to spend cheap money that will translate into 10 mph hour improvements. Ha! Never works that way. We instead spend thousands for many small incremental improvements.
Well, it used to be Los Angeles . . . 50 miles north of Fresno now.

Amen to that.   Too bad it is not obvious which incrementals add up and which cancel each other out . . . . . . . . . .

Stainless,
It was last April at Wilmington with a new bike. The monsoons hit so nothing to back it up. I also have a Land & Sea engine dyno but have never made a ceramic vs steel run. We put ceramics in place of everything we can but the motivation for testing is not worth the bench and dyno time to me. If I am being fooled by the claims to be better well then I have no one to blame but myself. I am a one man business so I will use that as my excuse for limited time and resources. Maybe a larger company that has more man power and a fatter wallet with back to back testing can weigh in with their results.

Stainless,
I should have indicated my dyno is engine only so I can not test complete bike.
