I've been asked this question a few times. This is the advantages of using ceramic bearings in your hubs, BB and derailleur pulleys. I will post 2 posts- 1) the advantages of all ceramic bearings, 2) A comparison between FSA Ceramic Bearings and Token Tiramic Bearings. Advantages of ceramics: 60% Lighter Than Steel, 2-1/2 Times Harder Than Steel, No Oxidation, Better Surface Finish Less Heat Development Increased Rigidity Less Vibration No Galvanic Current Low surface roughness More Durable - Last 5-10 times longer than steel Not prone to contamination. Ceramic balls are antimagnetic and electrically non-conductive ceramic bearings require less power (watts) to move Very Low Friction - Ceramic balls are rounder and smoother than steel Very resistant to dirt and dust Very stiff balls which make for a more stiff wheel/bottom bracket Higher tolerance What does all this mean to you and me? TESTING DATA Tests by SKF, and confirmed by the Danish cycle magazine Cykel Magasinet (Sept 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 Dura Ace pulleys consume 0.78W @ 500rpm, ceramic pulleys use less than 0.06W. A 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. Tests by the Danish magazine Cykel-Motion (March 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%. So, it comes as no surprise to learn that top professional riders are using ceramic bearings to win major races The results are great, riders are convinced. The math explains it. 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. Comparison: Token & FSA :

Hope this answers your question. Please let me know!

You guys should come and play over here with us in Taiwan !!! Here we have some STYL BULTE!! We can do Huhuanshan - It starts at about 300m above sea level and goes to 3500 in 55km. There is a break of about 400m where you are not climbing - the rest is just UP UP and UP again!!

And this is the Road bike- same - All Token Carbon Componentry - Shimano 105 STI's and Ultegra derailleurs. Bike as you see it - 7.5kg Size 54

This is the new Token Tribike with full Token Components and All carbon !!!! I had a P3C, - this is more comfortable and as stiff!!

Come from the same factory. On the website you can see a profile of the rims. I would say close to 80% of all carbon wheels out there come from this factory.

Hey Spinnekop, If he doesn't - let me know. I'm not close, but I can follow it up for you. They are on the road at the moment with some of the parts introducing it to bikeshops all over SA. Also give me a shout when he replies. I also put some more info under the gear review section about Token wheels and ceramic bearings if you want to read that or you can find more info on the website or if you have more specific questions you can e-mail me. Keep me updated!

If you guys go to the website www.tokenproducts.com - the rd bike in the news section is mine. You'll see the specs there as well - it pulls the scale to 7.5kg as you see it in the picture. With the 38mm carbon tubulars and all. Ride hard!

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 Sorry to jump in here, but I work for Token and we've just started to get into SA. The products have been available for a while but no advertising has been done. So we got a new distributor and they are touring SA at the moment with the parts. About side winds- what side winds - I race and train in Taiwan and Asia and have been in some fairly strong winds. Haven't had a problem so far. Yes - you don't use deep section wheels in a storm - that's just logic. The wheels and frames are made by the same companies that make VERY WELL known brands. Although some people refuse to believe that most European brands actually come from Taiwan. Even the handmade in America brands are from here. About the price- we're not trying to get rich from selling one wheelset. You can contact Triangle Sports for prices or ask your local bikeshop to contact them at paul@triangle.cc or 041 581 7990. All parts have a 2 year warranty- wheels - weight limit 90kg. The ceramic balls- some other well known brands buy the balls from Token. We use Tiramic bearings. That is titanium coated cones and races with solid ceramic balls. the ceramic balls are Si3N4. According to tests done in Australia earlier this year a rider can gain an average of 30m/km with the same energy expenditure, using Tiramic bearings. If you have any questions please feel free to contact me and visit our updated website www.tokenproducts.com Take care & ride hard! Attie Slabbert
