Unique Hunt, Hunter.

Pros:

• It surely makes handling on downhills stable, precise and playful and I'm sure in a deep snow it's less resistance than a tire punching through.
• It surely gives the bike such preferable handling characteristics to a front tire.
• This gadget will make a bike a drift machine on snow.
• I could feel that the ski was easier to ride through the snow. Going downhill the ski was definitely much faster than the tire alone.

Cons:

• Nothing for this hunt, simply a unique and useful product.
