Serious roller hockey players, these Player's Choice wheels deliver that perfect blend of grip, speed, and durability for indoor surfaces. The dual-pour construction is genius - a slightly softer inner urethane band for flex and rebound, combined with a harder outer band that takes the brunt of wear and tear. The Super High Rebound (SHR) urethane means these wheels snap back to shape quickly after compression, giving you more speed with less effort. The 74A hardness is extra soft, making them super grippy right out of the box but still able to slide when you need them to. They're ideal for players under 185 pounds on smooth surfaces like sport court or wood, but not recommended for outdoor use. The unexposed hub design with 12 hollows creates a strong bond between urethane and hub, resulting in more flex for maximum grip. While they might be slightly heavier than 5-spoke hub wheels, they're stronger, grippier, and more durable for aggressive play. This 4-pack of 59mm wheels lets you customize your setup - just make sure to measure your current wheels or check your skate specifications since manufacturers use different sizes. If you want wheels that offer professional-level performance with exceptional grip for quick stops and turns, these dual-pour wheels are definitely worth trying for your next indoor season!
