moi j'ai des roulement ceramique pour mon pedalier et c'est super
il y a une video ici et la comparéson de poids avec des standard et des hybride aussi

pour moi le full céramique on l'avantage d'avoir peut de fiction et d'être light mais ils sont pas précis comme un hybride ou un standard (ils on toujours un peut de jeux..)
pour ce qui aime les stat

ESTING 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.
