Product details
The Ceramicspeed derailleur 91802 is a highly advanced bearing suitable for all disciplines. With an inner diameter of 15 mm, an outer diameter of 24 mm, and a thickness of 5 mm, it offers superior performance compared to standard bearings. The use of ultra-smooth silicon nitride balls and polished hardened steel grooves significantly reduces friction, leading to a longer lifespan and improved power transfer. The reinforced polyamide cage and special seals protect the bearing from dirt and moisture, further enhancing reliability and efficiency. This bearing is not only 400% smoother but also 128% harder and 58% lighter than conventional steel bearings, making it an ideal choice for demanding applications.
