Here is the solution to the problems with the Voile crampon. The adapter with which it is possible to mount and unmount the crampons without unfixing the binding of your splitboard.
It takes a lot of effort to modify the Voile crampon, flexing (saw), drilling, screwdriving,.... In this effort, and a price of 45-60 € you can think about selling you Voile crampon, and get the new Phenix crampons for 88 € and it does not requires any further adjustments.
Top development, a tribute to Phenix.
