New : Cyclocross/MTB - Include new custom designed cover shield for increased protection against external elements like moisture and dirt.
Ceramic bearing = free speed with same effort.
C-Bear specialized in ceramic bearing for bi-cycle.
Ceramic hybrid bearing : ceramic balls are harder, higher heat resistance and rust free.
Right from the beginning (since 2007 its inception), Bart (founder of C-Bear) an avid cyclist, knows first hand and differentiates race (road) and cyclocross/mtb bi-cycle bearings.
C-Bear BB30 bearing is a set with 2x6806 ceramic hybrid bearings.
Race - aim at least friction, smooth spinning, maximize speed with the same energy.
Cyclcross/mtb - different specification to offer more protection against foreign elements like water and debris. After a short break-in, you will feel no difference.
BB30 (61806 also refer to as 6806) is bearing with dimension of 42(OD) 30(ID) and 7(depth).
