Nitro Vertical ST 26/27

Who is this splitboard binding for?

Nitro Vertical ST is intended for riders looking for Spark-based Nitro softboot binding for long tours and direct freeride descents. Nitro Vertical ST is most versatile with a medium-stiff splitboard boot. Prioritise firm heel hold, minimal lateral play and an outer boot length that fits the chassis without forcing the straps or highback out of position.

How does the system work?

Nitro Vertical ST uses Spark Tesla T1 with ST components. With this system, the connection from boot through highback and baseplate to the board determines how much input reaches the edge on traverses and turns.

What is included and what else do you need?

Manufacturer package for Nitro Vertical ST: a binding pair and the ride/tour hardware specified by the manufacturer
Plan separately: Confirm whether pucks or ride-mode interfaces are included. Add compatible crampons where your tours require them.

The exact package matters with this model because missing interface parts are system-specific rather than universal accessories.

What changed from the previous season?

Nitro Vertical ST appears in the 26/27 range in this configuration. With no reliable change list for a direct predecessor, we assess its system, fit and package without claiming an undocumented redesign.

Which size should you choose?

Available Nitro Vertical ST sizes: S/M, M/L. Use the boot’s real outer length: heel and toe should remain centred, straps should operate in their intended range and the boot must not move laterally in the chassis. When in doubt, measure the boot’s outer length and compare it with the current chart because identical labelled sizes can vary substantially between brands. Our boot and binding compatibility guide explains how boot flex, highback and board stiffness interact.

Have we tested this binding?

We are preparing a new 26/27 review of the Nitro Vertical ST. Until it is published, this page provides technical guidance without presenting a test verdict in advance.
