Selling a pair of BD Helios in a 168cm, 88mm underfoot. These are going EXTREMELY cheap. The reason being, a friend gave me to these to try and salvage a hack job mount, but unfortunately was not able to. As you an see from the pictures. These would accept a larger BSL than was drilled for (26.5-27 mondo), or if you were to mount forward or back of the original mark. Bases are in great shape, and the edges are sharp. Really light and stiff ski made for ski mountaineering. $100. Buyer pays shipping or local pickup if you're near Pinedale/Jackson area.
