Bont Royal Assassin, Derby Edge, 59mm x 38mm 8 pk
Royal Assassin Derby Edge
Narrower Hub. More Lip. More Control.
The Royal Assassin Derby Edge returns to the narrower hub design trusted by derby skaters for years.
By reducing the hub width, more urethane sits outside the hub to create a defined outer lip. That extra lip increases edge grip, improves corner confidence, and gives skaters a more connected feel during aggressive lateral movement.
For derby, that matters.
Whether you are driving through a wall, accelerating out of apexes, or holding hard inside edges, the Derby Edge is built to stay planted without feeling sluggish.
Why Derby Skaters Choose the Derby Edge
More Edge Control
The narrower hub allows more urethane flex at the edges of the wheel, creating stronger bite during tight turns, quick cuts, and lateral pushes.
Predictable Grip Without Feeling Slow
The flexible urethane formula creates grip through rebound and flex, not just hardness. That means the 92A performs reliably across most indoor derby floors without feeling sticky or dead.
Faster Engagement Into Edges
The added lip helps the wheel engage earlier when leaning into turns, giving skaters more confidence when pushing hard into corners or quick directional changes.
Built for Derby Impacts
Designed to handle the heavy forces of roller derby, from explosive starts to constant lateral pressure, while maintaining long-term performance consistency.
Long Lasting Performance
Royal Assassin wheels are known for durability and consistent feel over time, often lasting significantly longer than many standard derby wheels.
Why the Narrower Hub Matters
Most modern hubs extend close to the edge of the wheel. This increases rigidity but reduces urethane flex.
The Derby Edge intentionally uses a narrower hub to allow more usable urethane around the edges of the wheel.
Benefits include:
- Increased edge grip
- Smoother transition onto edges
- Better corner confidence
- Improved control during lateral movement
- More forgiving feel under pressure
For derby skaters, this creates a wheel that feels planted, controlled, and responsive without becoming overly rigid.
Designed With a True Derby Lip
The updated Derby Edge profile restores the defined outer lip preferred by many competitive derby skaters.
Unlike rounded speed-style profiles, the Derby Edge lip helps maximize contact patch engagement when leaning aggressively into edges.
This creates:
- More confidence in corners
- Stronger push-off grip
- Better stability during blocking
- Improved control during fast transitions
