01
WHY FOUR WHEELS
Four wheels create the geometry figure skating needs.
An ice blade has three balance zones. Three wheels give two. Four wheels give three.
Geometry and wheel spacing
Three wheels pivot
The skater tips between front and rear.
Four wheels create a center
Two middle wheels form a stable skating zone.
Support continues behind the boot
The frame feels more familiar to an ice skater.
DIRECT COMPARISON
Three wheels, four wheels and an ice blade.
The ice blade and four-wheel frame both support front, center and rear balance zones.
- Front uses the front two wheels
- Center uses the two middle wheels
- Rear uses the rear two wheels
- Three wheels have no central pair
WHEEL SPACING
Close contact points make turning easier.
EDGE uses wheel diameters matched to each frame size so the spacing remains close and consistent.
- Smaller frames use smaller wheels
- Larger frames use larger wheels
- Contact points remain close
- Less lifting is needed through turns
Four wheels create three balance zones. Close spacing makes them usable.
02
ADJUSTABLE ROCKER AXLES
Change the position of every wheel.
Adjust each rocker axle to move the wheel higher or lower in the frame.
Settings and variations
Loosen one side.
Rotate the other side to change the rocker axle position.
Tighten it again.
THREE STARTING CONFIGURATIONS
Flat. Regular. Defined.
FLAT
All four wheels on the floor.
More wheel contact for stability and faster directional skating.
REGULAR
General figure skating.
The standard starting point for jumps, spins, edges and turns.
DEFINED
More maneuverability.
More movement for turns, edges, slalom-style movement and pick-free skating.
FLAT
Outer wheels lower. Center wheels higher.
This places all four wheels on the skating surface.
REGULAR
All four rocker axles face the same way.
This creates the regular EDGE setup.
DEFINED
Outer wheels higher. Center wheels lower.
This creates a more defined setup and greater maneuverability.
REAR BIAS
Three rocker axles down. Rear rocker axle up.
Adam uses this variation for more maneuverability through backward turns.
One frame. Different setups.
03
INDOOR AND OUTDOOR WHEELS
Two complete wheel sets.
Blue for indoor skating. White for outdoor skating. Both included.
Wheel construction and specifications
Dual-durometer construction
One wheel. Two compounds.
Each EDGE wheel is one wheel made with two durometers. The outer compound meets the skating surface. The inner compound supports the wheel.
BLUE
Indoor wheels
85A inner
Softer on the outside for grip and edge feel. Firmer on the inside for support and rebound.
Sealed wood
Indoor rink floors
WHITE
Outdoor wheels
82A inner
Harder on the outside for outdoor durability. Softer on the inside to preserve feel and rebound.
Polished concrete
Smooth outdoor surfaces
16
Eight blue indoor wheels and eight white outdoor wheels are included with every complete EDGE system.
Bearings and spacers are already installed in every wheel, so changing between sets is quick.
One system. Two surfaces.
Wheel setup
Loosen the nearby screws
When changing either of the two front wheels, loosen the nearby screws first.
Loosen the rocker axle
Remove the wheel
Align the replacement wheel
Reinsert and tighten the rocker axle
Wheel-change tips
Check the aluminum spacer
If the rocker axle does not slide through easily, the spacer inside the wheel may have shifted slightly.
Realign it with the tool
Insert the tool through the center and move the spacer back into alignment.
Tighten before skating
Tighten the rocker axles and nearby screws before skating. Loose hardware may begin to rattle.
04
EDGE PICKS
Front contact matched to the frame.
Big enough for jumps and spins. Small enough to stay out of the way on deep edges, turns and crossovers.
02
2 sets of EDGE picks matched to frame size are included with every complete EDGE system.
EDGE pick design and clearance
210mm and 230mm
Matched to the smaller EDGE frame sizes.
250mm, 270mm and 290mm
Matched to the larger EDGE frame sizes.
WHERE THE PICK MEETS THE FLOOR
Clearance changes with the balance zone.
Center zone
On the two center wheels there is more room before the pick reaches the surface.
Front zone
Move onto the front two wheels and the pick makes contact earlier.
MATERIAL
Grip for jumps. Slip for spins.
A grippier compound helps jump takeoffs and fights you on spins. A slippier compound spins well and lets go on jumps. No compound is perfect on every surface, so the EDGE pick material is set for the surfaces inline figure skating belongs on: smooth hardwood and polished concrete.
Adjust the pick. Keep the contact familiar.
Spin guidance
Press as lightly as you can.
Press hard and you stop. Press as lightly as possible and you spin faster. This is the single best spinning tip Adam has been given, from a former world champion.
Learn it backwards, on two feet.
Skate backwards on two feet, come onto the pick and travel as far as you can.
Then one foot.
The same drill on one foot. Now you are learning the balance as well as the pressure.
Then the left inside edge.
The same drill on the left foot on an inside edge, which is the position an upright spin actually uses.
WHY IT WORKS THIS WAY
Wheels roll forward and backward, not sideways. An upright spin is a series of very small back loops, so you travel in a tight circle rather than turning on the spot. That is why you stay slightly over rather than completely upright.
EDGE pick adjustment
Loosen the side screw using the tool provided
Unscrew and remove the EDGE pick
Screw the replacement EDGE pick into position
Set the preferred height
Tighten the side screw using the tool provided
AS THE PICK WEARS
Reset the height to restore the front contact you had. Adjust the left and right EDGE picks to the same position before skating.
05
PICK-FREE SKATING
Skate with or without a pick.
Replace the EDGE pick with an EDGE plug whenever you want a completely pick-free setup.
02
INCLUDED
Two EDGE plugs are included with every complete EDGE system.
Why skate pick-free?
Remove the EDGE pick and install an EDGE plug in its place.
Remove the EDGE pick
Install the EDGE plug
Push from the wheels and edges
Skate without accidental pick contact
TWO WAYS TO SKATE
Pick. Or pick-free.
EDGE PICK
Front contact for technical elements.
Use the EDGE pick for spins, pick-assisted jump takeoffs and movements that rely on front contact.
EDGE PLUG
A completely pick-free setup.
Remove pick contact for edge work, turns, teaching and skating that does not require jumps or spins.
Learn to push from the edge.
Without a pick to push against, the skater must stay on the wheels and create power through the skating edge.
Stay within the center zone.
Pick-free skating encourages the skater to remain supported through the center zone during edges, turns and connected movement.
Increase front clearance.
Removing the pick creates more freedom when moving onto the front wheels during deep edges and turns.
Explore a more defined setup.
Skaters can use more movement through the front of the frame without the risk of catching the pick.
One frame. Two front-contact options.
06
HONEST COMPARISON
Built from what was missing.
EDGE exists because of the systems that came before it. These are the design differences, shown rather than claimed.
Detailed comparison
BUILT-IN SPACERS
Fewer parts in your hand.
Most systems use loose spacers that sit inside the wheel and fall out with it. EDGE builds the spacers into the frame.
ONE TOOL
One side, not two.
A loose-spacer axle needs a tool on each side at the same time. A rocker axle releases from one side.
ADJUSTABLE PICK
Wear does not move your contact.
A fixed pick sits lower as it wears, so you reach higher and your balance into loops and choctaws changes. An EDGE pick resets to where you set it.
ADJUSTABLE ROCKER AXLES
Not one fixed profile.
A fixed setup is whatever the frame was built with. Every EDGE wheel raises and lowers independently, so one frame can be flat, regular, front bias or rear bias.
EDGE
Frame, wheel, rocker axle, screw. Take a wheel off and that is what you are holding.
LOOSE-SPACER SYSTEMS
Frame, wheel, axle, two screws and two spacers. Two more pieces to line up, and two more to lose on the floor.
ABEC-9 bearings as standard
Fitted in every wheel, indoor and outdoor, with spacers already installed.
More boot sizes per frame
Three mounting positions at the heel widen the range of boot sizes a single frame fits. For a growing skater that can mean a new boot without a new frame.
Indoor and outdoor included
Two complete dual durometer wheel sets ship with every EDGE system rather than being bought separately.
Pick-free is built in
The EDGE pick comes out entirely and an EDGE plug goes in its place. Nothing to push against, which is the habit most inline skaters do not know they have.
WHERE THIS CAME FROM
Nicolas Perna and the skaters around him built this category decades ago. Adam skated on those systems for years and is here because of them.
Nothing here is an attack on that work. It is what a skater builds after using everything available and finding the parts that were missing.
Built on what came before. Designed around what was not there.
