CeramicSpeed Bearing 61805 6805 25x37x7mm

Bearing 61805 (6805) - inner diameter 25mm/outer diameter 37mm/thickness 7mm The components of the bearings are made of materials that provide an ultra-smooth design, limiting friction. The balls are placed in a polyamide cage. Each ball is optimized with Ceramic Speed Low Viscosity grease to minimize friction and extend life. Dust caps are also placed to keep dust out. These bearings can be used in any discipline: road, time trial, triathlon, track, cyclo-cross and mountain bike. The benefits are reduced friction, improved power transfer and increased longevity. Ceramic Speed balls glide 400% better and are 58% lighter than standard bearings in the cycling industry. Each bearing is hand checked 4 times to ensure perfect positioning. Designed and assembled by hand in Denmark.
