The XMF 4AC represents a good compromise between a lightweight and durable pedal. Aluminum body and steel axle, providing a long service life, even in rougher driving in the woods. The pedals are all standard cranks suitable with MTB thread (9/16 ") and Shimano SPD cleats. Unlike many other pedals 3x sealed bearings per pedal are installed here. The shelf life is characterized by a multiple higher than for simple supported pedals. The release force can be adjusted on both sides to their own needs.
