Pads: D03S (resin), N03A (organic), N04C (metal). Real weight: 218 g (front), 229 g (rear). Disc brake system with the dual diameter opposed-piston caliper design has differently sized pistons in front and in the rear. The system adopts a power transfer system in which the disc brake rotor is pressed by the smaller sized piston at the entrance of the disc brake rotor intake and also by the more powerful larger sized piston at the back. This prevents the wobbling motion of the disc brake rotor and reduces noises significantly.
The 4-piston caliper also allows a wider contact area for the disc brake rotor while keeping the size compact, and the efficient location of pads is adjusted as necessary to stabilize the pressure. In combination use with the ServoWave lever it provides an incredible 50% more stopping power than the previous model. The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400C to 300C surface temperature.Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding was developed for quick and easy prevention of air in Shimano's hydraulic system. They've streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system. I-Spec EV creates a clean and action-optimized cockpit that provides greater focus and flexibility for a wider range of riders. Wider adjustment range allows riders of various styles, preferences and body styles to adjust to the optimal position. Ergonomic design, quicker lever access, and light operation enhance rider comfort and concentration. I-Spec EV increases brake lever rigidity by moving the brake clamp position inward to create an extra point of contact between the bar and the lever. This additional bracing drastically increases bike control and braking engagement while maintaining space between the clamp and support point for other handlebar accessories.
When you pull a Servowave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-disc contact so more of the lever stroke is used to apply greater braking power with improved control. Right lever: rear brake (hose length: 1700 mm).Left lever: front brake (hose length: 1000 mm). Kit includes: Levers, Calipers, Adaptors, Bleed Blocks, High Power Shimano Hoses, and Shimano pads. The brakes are pre bled but un-attached from the hoses. Rotors, olive and connecter insert not included. The kit will arrive in factory sealed packets (one packet per brake) direct from Shimano as they come with new bike builds.
They will not be in Shimano boxes. Please note that everything shown in images 6 and 7 is what is. 1 - The images show Ice tech pads. The actual brakes on offer arrive with standard. Ice tech pads can of course be fitted later.
2 - The brakes DO include brake mount adaptors (that are not shown in the images).
