Telemark Bulldog

 

Simple. Effective. Original Design.

CONSTRUCTION: The main parts of the binding are machined aluminum. This includes the wings, center aluminum block, pin plate and toe cross bar. There is a plastic insert in the aluminum center block which also machined. The remainder of the parts are stainless steel.

WEIGHT: Currently at about one pound each unit (32oz for a PAIR).

DESIGN: Based on 75 mm Nordic norm 3-pin; cantilever front hinge; three cross bars unite the lateral wings; center block with locking spring pin and front toggle release; integrated ski brake provides upward lift to lateral wings which maintains them open; when the boot is inserted, downward pressure retracts the ski brake under lateral wings.

SPECIAL FEARTURES: Step-in design, integrated ski brake, utilizing solely a toe piece to hold the boot in place.

A variety of features make this telemark binding unique: some obvious, but several more subtle. Starting with the most obvious, of course, is loose that heel strap!. This won't be for everyone. But for those hard core, die hard, 3-pin lovers, it's a great leap from the old front throw. The convenience of a step-in with a ski brake, alleviating the retention strap, will be a welcome advantage for many. Personally, I find that the combination of a plastic telemark boot with a heel cable is much too restrictive. This binding performs well on hard pack as well deep snow conditions. It has a broad, flat boot platform that efficiently transfers carving energy. Boot rocker and forward throw are minimal with this design.

What are the mechanics that make this binding work? The key to the design is the cantilever hinge in the front of the binding, and a center block, which supports the lateral wings. When applying force downward on the lateral wings there is mechanical advantage produced which applies a significant force to the toe of the boot under the top cross bar. This holds the ski boot in place firmly. In addition, the three-pin plate is slightly higher than the rest of the binding's top surface. This allows for a precise, tight contact between the boot and the three-pin plate. This feature also raises the toe of the boot slightly higher than mid sole minimizing rocker.

A raised ridge is machined across the mid aspect of the pin plate which gives some extra purchase on the boot sole. This feature creates a snug fit, eliminates 'slop', and minimizes wear on the pinholes. There are two upright posts in the front of the binding which stops the front of the boot when stepping into the binding and aligns the pin holes correctly every time. This also saves wear on the pinholes and allows for easier and quicker step-in action.

You will also notice that the boot/binding interface surface is smooth and unencumbered by screws or sharp edges, which prevents snow from catching under the sole of the boot. This alleviates the annoyance of a big wad of sticky snow under the sole while skiing a sweet crud line. The boot platform is slightly angled downward towards the rear of the binding, also minimizing rocker effect.

The ski brake is one piece, and tucks neatly under the lateral wings when the binding is locked down. It is spring activated upward and holds the binding open. The ski brake also prevents the ski from sliding forward when inserting the boot.

The center block of the binding attaches directly to the ski with a four screw mounting pattern. It is made of 1 x 2-inch stock aluminum and produces a 1-inch riser effect. The front release toggle is attached directly to the locking pin which extends the length of the binding through the center block. The binding is locked down by the center pin latching across the rear cross bar. There is NO safety release mechanism designed into this binding. You step out of the binding by manually depressing the front toggle downward with a ski pole.
