The Endless SJR UFS Frame is Stephen Johnstone's signature powerblading frame with optional Siders for UFS skates. Stephen has personally tested and proven the performance of this frame at urban street sessions, pump tracks, and skate parks. This frame is ideal for aggressive skaters looking for a compact and rigid big wheel experience that can smoothly carry speed through city streets and also grind at the park.
The dedicated 4x84 setup features our Enhanced Flat micro-rocker that feels like the worn-in flat setup on your aggressive skates, but without feeling rockered. This goldilocks geometry is fine-tuned for control and stability especially when performing tricks or jumps. For skaters wishing to unlock grinds and soul tricks, this frame set is available with optional Sliders that bolt onto the outside of the frame.

Better by design
The structural design of the SJR Frame is adapted directly from our previous UFS powerblading designs. Its thick walls are internally bridged to increase rigidity and allow optional Sliders to mount to both sides. For the SJR Frame, however, we optimized ride height for a single 4x84 configuration, and one-piece steel axles were chosen to simplify wheel installation and rotations.
The Sliders are made from a low-friction, high strength thermoplastic. The geometry was meticulously engineered to reduce the grinding surface while promoting positive lock on ledges and standard size rails and coping found at skate parks.
This 4x84 setup is uniquely suited for both street and park skating by taking advantage of an optimized characteristic of this wheel size. Stephen found through extensive testing that 84 mm wheels accelerate well and sustain speeds almost as fast as 90 mm wheels, but they are small enough to allow more ergonomic topside grind tricks.
