Grivel crampons regulation bar for small size boots.

In this short video I show the procedure to reduce the lenght of the regulation bar on Grivel crampons, to fit the crampon to small boots. You just need to remove the bar, turn it 180° and replace it on the other crampon (in order to maintain crampon both right and left). The function of the regulation spring is to hold the front section in place, but it can be removed (after taking off the regulation bar) and replaced with a screw and bolt: this gives you an extra two sizes.
