For the past several years now Spark R&D has catered to the needs of hardboot riders by offering Dynafit Adapter-Plates for use with Dynafit Toe-Pieces. Building off of the great success of their pinless Tesla System, Spark R&D has launched their first ever Hardboot binding, the Dyno DH. Like the rest of the Tesla line, this new binding works with the tried and true Voile puck system.

“With the introduction of the Tesla System it made the hardboot binding a piece of cake.” – Will Ritter Founder/Owner Spark R&D

Will at Spark stated they’ve received numerous requests over the years to build a hardboot binding and he’s excited to include one in this season’s lineup. During the early development period they worked on designing an elegant way to utilize bail-wires to secure the slider-pin in place (much like how the the toe strap lock the pin in place on the Blaze and Burner models) but were unable to find a suitable solution. With last year’s introduction of their popular pinless Tesla System came a new opportunity to revisit the hardboot design where slider-pin retainment was no longer an issue.

How it works

During the descent, the Dyno DH binding is slid over standard Voile pucks and secured into place by the locking the toe-ramp design of the Tesla System. For the ascent, the Dyno DH is removed and stored within the rider’s pack.

Splitters then step into their Dynafit Toe-Pieces and utilize Voile climbing-wires for the tour up. Spark R&D recommends Dynafit’s Speed Radical Toe Pieces for maximum functionality and minimal weight.

With the addition of the Spark R&D Dynafit Adapter Plates, splitters can mount their Dynafit Toe-Pieces using the factory drilled touring bracket inserts. To finish the system off, Spark R&D has also launched their D Rex Crampon designed specifically for Dyna-Splitters and the Dyno DH binding.

With benefits of reduced weight, better edging while touring, and quick transitions, it’s safe to say the hardboot movement is here to stay.
