Why We Like The Expedition Splitboard Binding

Many split-specific bindings are focused on making it easier to get to the top, but at the cost of downhill performance. Considering that our ultimate goal is to score fresh powder on the way down, Union designed the Expedition Splitboard Binding to deliver the closest feeling possible to shredding on a solid board with standard bindings. It also has simple design that minimizes moving parts, not only lending a solid feel, but also making it quick and easy to switch over at the top.

  • Split performance on the way up, and a fun, solid ride down
  • Union Split interface offers extremely solid connection
  • Duraflex CB SP2 base is stiff for efficient backcountry travel
  • EXP2 highback increases the response without the weight
  • Nonstick EVA footbed absorbs vibrations and impact
  • ExoFrame 2.0 ankle strap conforms to your boot
  • Magnesium buckles are lighter, yet 4x stronger than aluminum
  • Union Split System allows binding to be mounted to solid board
  • Item #UNNZ08S

I've put it through the wringer
True to size

I cannot warn you against these bindings enough. I put them through the wringer and tried to get my set up tuned all season last year, but had constant, very serious issues with these. The pin system does NOT stay locked. Then pin unlocked on every tour I did, and several times the pin came completely out. Once, while bombing a hill, my back binding literally completely detached from the board. I talked with people at Union (who begrudgingly told me this was an issue they have seen before). They sent me all new pins and hardware and we tried to solve the issue. While the customer service was great, it did not make up for how bad these bindings were. On a separate occasion, unrelated to the pin, my binding fell off AGAIN, this time, because it pulled away from the baseplate (completely stripping it). Union had to send me a new set of baseplates from their older model that used much sturdier metal. I told people at Union that this item needs to be recalled. They assured me that my binding was just faulty (though they didn't offer to replace it). I have found several other instances of this happening to other people.

A bit frustrating

I've put it through the wringer

I went with these bindings as I was focused on the ride down. The walk up was comfortable but the pin system is a total pain. The pin backed out during a tour and snapped the eye hole to the touring bracket. The locking mechanism is fairly pointless. Union replaced but their warranty system does not focus on speed. The pin would also backed out as I road down on occasion. Part of the issue is getting the pin fully through the binding. The pin could be a bit longer and it was always a fight to get it properly set. The area where you lock in the pin also gets jammed with snow and really leaves a lot to be desired with functionally. This is the only backcountry binding I really used with great frequency. The ride down is like a normal binding but not would like to know how much control you would really lose with another option. The pin drove me nuts but the ride down always felt like I was on a normal binding.

can you post a pic of what you are talking about? I'm thinking of getting these bindings for my split board but having trouble understanding what you mean about the pin


Union Split System allows binding to be mounted to solid board... how realistic would it be to use these primarily on your solid board, if you only skin a few times on a split board?
