The objective of the Sunn Kern AM S3 is to make all practice accessible; climbs, off-piste descents and walks with friends. For those who want a bike to do it all, here is your ideal All Mountain MTB.
Its new 6061 aluminum frame offers the best compromise between strength and lightness, while its “sloping” side allows the bike’s center of gravity to be lowered, while facilitating the rider’s movement. Its “VR” kinematics, a virtual point of rotation that varies according to the depression of the oscillating arm, promotes pedaling at the start of the race and damping at the end of the race. Its progressive “LR” leverage ratio allows the bike to maintain a constant attitude and consumption of travel that is neither too fast nor too slow. For even more pedaling performance, the Kern AM S3 is fitted with a pair of 29 inch wheels.
Main features:
- Alloy 6061 frame, 130 mm travel.
- Sram SX Eagle 1×12-speed drivetrain.
- Shimano MT200 hydraulic disc brakes, 180/180 mm.
