10. Front Brake
The front brake (Figure 10.1) is hidden from the wind and from your eyes. But when correctly
assembled and adjusted, they work very well. The Speed Concept brakes use wedge/roller
actuation, so cable tension is critical.
Before starting this procedure, the front brake cable and housing should be in place after
installing the aerobar.
