Built for intermediate freestyle skaters working through singles and early doubles, the Ultima Matrix RXS Freestyle System Kit brings Jackson Ultima's Runner Exchange System to your setup. Instead of retiring a whole blade when the steel wears down, you swap in a fresh runner in seconds and keep the same sweet spot every time.
Who It's For
This kit suits intermediate freestylists landing single jumps, building toward doubles, and refining their spins. The Freestyle profile delivers dependable edges and predictable take-offs, so your progress isn't reset every time your blades need replacing.
Geometry & Spin
An 8-foot rocker paired with a 7/16" radius of hollow gives you a balanced glide with secure grip through edges and spins. The diagonal-cut toe pick is matched to freestyle jumping, while the tapered runners hold clean edges and keep your skating quiet.
Steel & Exchange System
Each runner is Japanese AUS8 stainless steel set into a lightweight aircraft-grade aluminum chassis. The runners fit standard sharpening machines with no special jigs, and the profile sharpens all the way through with no flat spot behind the pick, aiding your axel take-offs. The kit includes everything you need to make the switch yourself.
