Advantages : Ceramic Bearings
Speed:With C-BEAR ceramic bearings you bike 4% faster:
not a kilometer but 1040 meter in the same time.
Endurance:Ceramic bearings reduce friction.
Result? Your bicylce feels 340 gram lighter on a 8% climb.
Energy:If you bike 40 km per hour,
the bearings help to save you 3 w of energy.
Money:The bearings last three to four times longer.
Quality:Quality standard abec 5* grade 3**
Si3N4 Silicum Nitride ceramic balls***.
*ABEC is an industry accepted standard for the tolerances
of a ball bearing, developed by the Annular Bearing Engineering
ABEC 5 is mostly used as the industry standard. However, the ABEC rating does not specify many other critical factors, such as smoothness of the rolling contact surfaces, ball precision, material quality, seals and other components of the bearings and the grease used.
**GRADE standaard defines the roundness of the balls. Grade ranges from 2000 to 3, the smaller the number, the higher the precision.
