2027 Radar Graviton Fixed RTP (Alum)

2027 Radar Graviton Fixed RTP (Alum) | Fixed, for a Reason

The 2027 Radar Graviton Fixed RTP (Alum) is the trick version of Radar's rubber rear toe plate — full rubber over a contoured footbed, on an aluminium slalom plate. Built for the Graviton trick ski, where the rear needs to be predictable and completely fixed rather than adjustable, because you're loading and unloading it constantly through rotations.

Key Technical Features

• Full Rubber Construction: The whole wrap is rubber rather than a laced or dialled upper. It grips by stretch alone — tight, simple, and with nothing on it to shift mid-set or come undone.
• Contoured Footbed: Shaped rather than flat, unlike the standard rubber RTP. On a trick ski that shaping is what stops the back foot wandering when you're spinning on it.
• Aluminium Slalom Plate: Mounts to a conventional insert pattern, so it fits the Graviton and standard slalom skis alike, and can be moved between them.

Why You'll Love It

Intermediate to advanced, and specifically for trick skiing. Fixed is the point here — you want the rear in exactly the same place every time, not something that adjusts. If you're setting up a slalom ski that gets shared, this is the wrong pick; take the ARTP or the standard rubber RTP instead.

Quick Answers

Do I need this for the Graviton, or will a slalom RTP do?
Take the Graviton RTP. It's the rubber rear sized to the Graviton's true-centre inserts, so your rear foot sits where the ski is designed for it during hand and toe tricks. A slalom RTP mounts, but the position is a compromise.

Which size?
By US shoe size: XS–S 4–7, M–L 7–10, XL–XXL 10–13. Rubber should feel tight — on the boundary, go down.

Will it fit my ski?
It's built for the Graviton trick ski. The aluminium plate mounts to a standard insert pattern, so it will also fit a slalom ski if you want a fixed rubber rear there.
