Shimano Saint BL-M820-B + BR-M820 disc brake

For confident braking on the roughest terrain, the BL-M820 levers have a rough finish, tool-free travel adjustment and I-SPEC B compatibility.

For downhill and gravity riding, the SAINT hydraulic disc brake features a rigid caliper, 4 ceramic pistons and an integrated ICE TECHNOLOGIES heat management system.

Technologies

Free Stroke Reach Adjust

The distance between the grip and the lever can be adjusted to suit any size of hand and the rider's individual style and preferences.

I-spec

Integrated mounting system of the shift control and brake lever. Provides clean aesthetics, more space in the handlebar area and weight reduction.

Servo Wave Action

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.

Ice Technologies

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 400˚C to 300˚C 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

“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.
