The Fischer BCX Magnum's base plate is an impressive 67 mm wide. Together with the 42 mm toe bar of the NNN BC standard, this improves the ski or skates lateral control. The manual locking mechanism has proven to be the most reliable choice in variable conditions: ice that accumulates here and there responds well to the hand-operated lever but can jam an automatic binding. - Fits boot sizes 3552 - The BC Flexor bumper is firm and can be replaced without tools if needed - Weight per binding: 132.5 g - Package includes two bindings Note! This binding is compatible with (Rottefella) NNN BC boots, not with regular NNN classic track-ski boots.
