A bearing system which consists of a cup contains balls adjusted by a cone nut.
This system features high durability and good maintainability.
The key element of maintenance is to keep smooth rotation yet without a play.
An ideal adjustment is no play, without any friction, but this condition easily leads partial wear and requires frequent re-adjustment.
So we, MKS deliver our pedals “preloaded”-a slightly over tighten condition to extend maintenance span.
At initial ride, you may feel the rotation is not completely smooth, but after running in, it will be smoother.
And all of MKS pedals are hand-adjusted at final stage of assembly.
