Amazingly light, solid construction. Incredible traction on snow/ice.
The G20 crampons as shipped from the factory do not fit well on the 45.5 EU.
Move front bail to the front hole, rear bail to the rear hole. Leave the bolt in the center hole as shipped. Move the spring retainer to the third hole from the back. Rotate tension adjustment to the bottom position and then give it 15 thumb strokes to tension and you have a near perfect fit.
The G20 crampons are lighter than the CAMP Stalkers which I also own, and though the G20's do not appear to be as heavy gauge steel, they feel very rugged and much more precise (a scalpel vs. a cleaver), and fit much better on the Nepal EVO's.
I have no reservations in recommending the G20's to anyone who owns the Nepal EVO's in the 45.5 EU sizing.
