Features & benefits

• Excellent roll speed thanks to the high rebound of the X-Formula.
• Optimal balance of grip and slide – the wheels roll smoothly over rough surfaces, while offering controlled slides when needed.
• Increased shock absorption reduces vibrations and is easier on your joints when landing.
• Durable urethane blend for a longer lifespan and better abrasion resistance.
• V5 Sidecut shape minimises “wheelbite” and makes technical tricks and reverts easier.

Who it's suitable for

Ideal for street and park skaters looking for a durable, fast wheel with reliable slide characteristics. Also suitable for riders who often skate on rougher street surfaces but don't want to compromise on precise slide control.

Technical notes

• Suitable for standard axles (no integrated core)
• Recommended axle and spacer configuration as with standard skateboard wheels (use spacers for optimal bearing alignment)
• Supplied without bearings

If you have questions about compatibility with your setup (axle width / board setup), please provide the axle model and deck width so that we can recommend the right configuration.
