The Saint crank FC-M820 by Shimano - unmatched stability

Shimano Saint FC-M820 is the main point of reference for downhill sports, and has been for many years. When it comes to robustness and stability, no one can beat it thanks to the super-strong steel axle and steel pedal inserts. However, the Saint was also designed with weight in mind, as its balanced Hollowtech II construction proves. In this version, the FC-M820 comes as a crank with four chainring bolts including covers, but without a chainring. It is compatible with 68 mm and 73 mm bottom bracket shells and can be optionally equipped with a special chain guide and a bash guard.

Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
