KCNC’s CB3 introduces a unique improvement to the already popular C7 road brake. The cage surrounding the brake is not purely aesthetic, it increases the stiffness of the brake while decreasing flex during braking. This decrease in flex translates into an improvement in modulation.
The CB3 uses a symmetric dual pivot design, similar to the C7, maintaining the performance and adjustability of that system. The CB3 however, guided by the external cage introduces much less flex in both the pivots and the brake arm itself.
