SHIMANO SAINT disc brake 4-piston BL-M820 + BR-M820 | rear wheel
At Shimano, SAINT stands for absolute durability, robustness and maximum functionality. The brake is in no way inferior to that. This anchor is the best choice for anyone looking for the ultimate deceleration. Should it come to a crash, it was definitely not her fault...
The many years of experience of the Japanese can already be seen from the lever. The attachment is easy thanks to the foldable clamp. To save space on the handlebars, a compatible shifter can be attached to the I-SPEC B mount . This creates additional order in the cockpit.
The brake can be operated with two fingers. The ribbed surface of the brake handle gives you a safe feeling at all times, even on rough slopes. Of course, the technical details are also fully convincing. Thanks to the Servo-Wave mechanism, Reach-Adjust and Free-Stroke, you look forward to every braking.
The four ceramic pistons in the SAINT brake calliper show no mercy. If necessary, they pack brute force, but can also be dosed very precisely thanks to the good leverage. To avoid overheating, the entire construction is designed for rapid heat dissipation. This is further supported by the use of ICE-Tech brake pads with cooling fins. This means that longer descents in the high mountains are a safe bet.
mount is extremely easy thanks to the post mount and venting with the one-way bleeding system is no rocket science.
Servo Wave Action
The brake lever takes up a lot of braking distance right from the start of its movement. This means that the pads are in contact with the brake disc early on. After that, the transmission ratio changes and the larger part of the lever travel can be used for braking power and for precise dosing.
Reach Adjust and Free Stroke
Both systems are used for individual adjustment to the driver and his preferences. The grip width can be adjusted to the respective hand size without tools and thus the optimal braking force is always achieved even with shorter fingers.
In addition, the adjustment of the pressure point is possible. The sooner this starts, the shorter the idle travel on the lever. Again, everyone has their own personal preferences.
One-way bleeding system
This technology simplifies the maintenance of the brake system and makes bleeding easier over the long term. Because the mineral oil travels in only one direction, air bubbles have no chance of hiding. Any reasonably experienced screwdriver will always be able to set the optimal pressure point.
