The more severe the arc of the rockered ski, the easier it is to turn the handlebars. This is true because the less contact with the ground, the less resistance there is to turn. However, keep in mind that it is resistance that is needed to turn the sled. On some skis only 1" of a 10" carbide will make contact with the ice. |
I am not a fan of any aftermarket ski. I would rather you spend that money on a snowmobile trip. 10% of the time they may be better, but that's not worth $400.00 |

| Carbides, on a
rockered ski, will dull first at the bottom of the arc - where they receive the most
contact. More surface damage will occur because all the pressure is focused on the carbide. Once the bottom of the arc is dull, it will not allow the untouched carbide to penetrate. This is because the majority of the weight (or pressure) will still be at on the bottom of the arc. |

To raise the wear rod off the ground, the rockered ski will need 8"-10" of heavy wet snow. This is because there is not much lift from the ski until it is in deep snow. The focused pressure directly on the carbide will increase trail shaving in the corners. The wear rod ruts will be even deeper, generating more darting and requiring even more grooming and snow. Examples of some aftermarket rockered skis resting on the flat surface of a carpenter's level (notice the gap created by the arc): |

As you can see on the right, only 2" of the ski makes contact with the level. |

As you can see on the right, only 2 1/2" of the ski makes contact with the level. |
 |
As you can see on the right, only 2 3/4" of the ski makes contact with the level.

Rockered ski bottoms are arced (or curved) from front to back (as seen in the
diagram at the left). Rockered skis counteract the
cushioning effect that flat skis provide, because the more arc there is the less
straddling of bumps the skis can do.
As
you can see on the right, only 2" of the ski makes contact with the
level.
