The Lucky Quatro™ 110mm These wheels feature high quality Lucky urethane. These Quatro wheels are produced using our proven Lucky urethane formula with Lucky Rebound Technology™ (LRT™)
We have spent countless hours tweaking and adjusting our urethane formula and processes to improve the feel, performance, and durability of our wheels. Lucky Rebound Technology™ (LRT™) is a combination of high-performance urethane, a new pouring process, and a proprietary curing method which gives these wheels a grippy, fast, and buttery roll.
