AAAAHHHH! Thats what I missed. Thx.
What you want to know about them?
Stay away as far as possible from any side wind faster than 2km/h!!!!
I pesonally ridden deepsections in quite heavy wind and cross wind effect in min
Token, do you build these in your garage?
How much??? $$$$$
No way the rim height on that thing is 38! And there are so many ceramic bearings out there these days. No one ever mentions whether they are hybrid ceramic or full ceramic bearings. The top end bearings alone probably retail for more than that entire wheelset...
I agree- the rim height is 85mm to be exact. Please get all the information straight. To get the right info please go to www.tokenproducts.com
That is titanium coated cones and races withsolid ceramic balls. the ceramic balls are Si3N4. According to testsdone in Australia earlier this year a rider can gain an average of30m/km with the same energy expenditure' date=' using Tiramic bearings.[/quote']30m/1000m = 3%. That's a fair bit. Is there any published testing that can substantiate this?

30m/1000m = 3%. That's a fair bit. Is there any published testing that can substantiate this?
Tests by the Danish magazine Cykel-Motion (Mar 2005) and subsequently supported by calculation, show how using ceramic bearings can reduce rolling resistance by 50%, saving 22m in just 55 seconds at 32kph. In short, astounding speed improvement of 4%.
Further tests by SKF, and confirmed by the Danish cycle magazine Cykel Magasinet (Sep 2005), describe dramatic reductions in friction compared to conventional cycle bearings. For example:
With a pair of race wheels (total of six bearings), friction with ceramic bearings is reduced 22 fold, While Shimano Dura Ace pulleys consume 0.78W @ 500rpm, ceramic pulleys use less than 0.06W. A Campy Record BB @ 100rpm and 400W consumes 0.6W, the same BB with ceramic bearings consumes 0.02W
Ceramic bearings in your bike's bottom bracket will shave 1-2 seconds per KM. In a 40k time trial that is 40-80 seconds of free time gain!
Ceramic bearings in your bike's wheels will shave even more time.
The friction reduction of ceramic bearings aids a wide variety of riders. The advantage of ceramic units is greater at lower speeds. From a technical point of view, riders sheltered inside the peleton or riding off road have more to gain with ceramic bearings.
how much is this wheelset?
