Dude, if you're coming out of the 4FRNT Thunderbolt Ski Bindings, you'd better go on a diet or slow down. Seriously. This binding is the burliest in 4FRNT s line, maxing out at DIN 18. No need to apply if you ski on a DIN under 8, either.
Diagonal Toe 180˚ release in a twisting fall saves your knees.
Oversized AFD Four rollers and gliding inserts ensure consistent release and precise return-to-center.
Zero Ramp Angle Puts your boot sole in a neutral position for better switch riding
Interchangeable Brakes Fully interchangeable brakes in 78 mm - 150 mm widths
We recommend a brake width equal to or at most 15 mm wider than the ski waist width.
