Karakoram Prime-X W Splitboard Binding

The Karakoram Prime-X W Splitboard Binding is a light, responsive women's binding for riders who want to tour fast and ride aggressively on the way down. A 7 chassis and an 8 highback on Karakoram's 1-to-10 scale give a supportive ride, and a 7075-T6 aluminum open chassis keeps it at 596 g per binding. The package includes the Prime split interface and Ride Mode 2.0, in two women's sizes covering US 5 to 10, for long tours and steep lines.

Is This the Right Binding for You?

Best For
Women who want a light, supportive interface binding that rides firmly connected to the board, in sizes US 5 to 7.5 and 8 to 10.
Consider Another Binding If
You want a softer, more forgiving binding, or a puck-based system. The Spark R&D Arc ST Splitboard Binding uses pucks and a different tour-to-ride system.

Why We Like It

  • At 596 g per binding, with 1,984 g for the complete setup on a board, the Prime-X W is light for a binding with an 8 highback.
  • A 7075-T6 aluminum open chassis lets the board flex naturally and saves weight without giving up stiffness.
  • The Prime interface pre-loads the contact points, so the binding locks to the board with no play once the lever closes.
  • Women's-specific toe and ankle straps fit smaller boots more securely than a scaled-down men's strap.

Best Uses

  • Long tours where weight matters
  • Steep, aggressive descents
  • Women with US 5 to 10 boots
  • Riders who want an interface system with no pucks
  • Everyday backcountry touring

Mounting and Setup Advice

Choose the size by boot: the small fits women's US 5 to 7.5 and the medium fits US 8 to 10. Check that the boot centers on the chassis with even toe and heel overhang before mounting the interface.

The interface mounts to the standard splitboard insert pattern, so the Prime-X W fits any splitboard with standard inserts. Keep the interface hardware snug through the season.

The bindings, the Prime split interface and Ride Mode 2.0 hardware, and dual-stride heel risers.
What does the open chassis do?
The open 7075-T6 aluminum chassis lets the board flex under the binding instead of stiffening it, and it removes material to save weight.
