Ceramic Bearings by CeramicSpeed
CeramicSpeed ceramic balls are rounder, harder, smoother, lighter and more resilient than steel balls and ceramic balls from other manufacturers. CeramicSpeed ceramic bearings therefore last 3 to 5 times longer than other commercially available bearings. All CeramicSpeed bearings are manufactured by hand in Denmark under clean room conditions and are subject to a strict four-stage control procedure. Among other things, the size of the ceramic balls is checked down to the thousandth of a millimetre. Tests are then carried out in the laboratory or preferably by professionals in training and competition. CeramicSpeed bottom brackets guarantee you the lowest possible friction, optimised power transfer and maximum durability and also help you save watts and reach the finish line faster. It's not about seconds, it's about minutes!

Mal wieder eine Glanzleistung von allen bei BC: Freitags Vormittags bestellt und Samstag Mittag in Münster in Händen halten! Hammer!
Das Lager: Auch der Hammer! Einfach mit dem passenden Einpresswerkzeug für 24er (Hollowtech II) Achsen einpressen - Kurbeln ran und staunen.
UNBEDINGT mal ohne Kette die Kurbeln VORHER drehen lassen.
Nach dem Einbau: Die Kurblen drehen wirklich lange und - wie eine gut eingestellte Radnabe - drehen sie auch leicht von allein zurück, bis zum Austarieren.
Ist zwar nur auf dem direktgetrienen Trainer bis jetzt- aber man hat das Gefühl gar kein Tretlager zu haben. Es ist wirklich kein Widerstand spürbar. Kann es nicht in Watt ausdrücken. Obwohl Stages installiert sind - kann aber einfach nicht sooo gleichmäßig treten, um aussagekräftige Vorher-Nachher Watt-Zahlen zu nennen. Man merkt aber einen deutlichen (!) Unterschied (wäre auch krass bei dem Preis).
Wurde in ein Rose Reveal Six Disc mech. Ultegra (2020) eingebaut. Zur Haltbarkeit kann ich noch keine Aussagen treffen.
Klare Kaufempfehlung!
