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 Features & Performance Premium Gravity-Poured Urethane Developed by urethane specialist Scott Corey, this hot-cast formula delivers exceptional rebound, grip, and durability. Hand-poured in small batches for consistent performance. Precision 6061 Aluminium Hub Aircraft-grade aluminium provides excellent energy transfer while maintaining a lightweight feel and precise bearing fitment. Derby-Specific Shape The lip profile and groove pattern are designed specifically for roller derby, helping reduce break-in time while improving edge control from the first session. Small Batch Production Each run is handcrafted in limited quantities to maintain strict quality control. Technical Specs Size: 59 x 38 mm (derby-specific with edge) Hardness: 85A, 92A, 96A, 98A Hub: 6061 Aircraft-grade aluminium Set Size: 8 wheels Choosing Your Hardness 92A Best all-around option for most indoor derby floors. Offers excellent grip with strong roll speed. 96A Faster and firmer feel for high-grip floors or skaters wanting more slide and speed. Usage Focus Built specifically for indoor roller derby training and competition on: Polished wood Sport court Coated concrete Optimized for: Tight cornering Explosive acceleration Lateral stability Edge control under pressure Handcrafted Character Because each wheel is handcrafted in small batches, minor aesthetic variations such as tiny air bubbles, swirl marks, or light hub markings may be visible. These are normal characteristics of hand-poured urethane and do not affect performance. Important Notes The natural urethane may yellow over time with UV exposure. This is normal and does not affect wheel performance. These wheels are not designed for drag stopping. Flat spotting caused by excessive dragging or improper bearing installation is not covered under warranty.
