Grivel G14 Antibott
Here's what other sites are saying:
If you love walking around with five pounds of snow stuck to your crampons, then you should definitely not buy the Grivel G14 AntiBott Plates. On the other hand, if you like your crampons to function properly, then you should consider it. This piece of rubber fits under your Grivel G14 crampons to keep snow from balling up and sticking, which besides being seriously annoying, is incredibly dangerous when you're 10-pointing above exposed terrain.
