Shimano's advanced brake levers with Saint ICE Technologies feature shorter, more ergonomic handles that offer tool-free grip adjustment and an adjustable pressure point for ultra-customization. The disc brake system features a brake caliper with counter-rotating double pistons. The front pistons have a different diameter than the rear. The system uses a power transfer technique in which the small pistons grip the incoming disc and the stronger, larger pistons grip the outgoing disc. This reduces brake disc flutter and makes the brake significantly quieter. The four-piston brake caliper increases the contact area with the brake disc while remaining compact in size. The position of the pads is precisely adjusted to stabilize the pressure. In addition, when combined with the SERVO WAVE brake lever, an incredible 50% more braking power is achieved than with the previous model. The advanced SAINT/ZEE disc brake system can be adapted to the rider's braking habits and produces consistent, excellently controllable braking power.
