Radar Crush is the first and only wheel designed specifically for outdoor roller dance. Manufactured in the USA, the Crush wheels offer a dazzling combination of control and feel. At 48mm tall, transitions, spins, and crazy legs are easy and fast. High rebound 84A (Lavender) and 88A (Seafoam) formulas offer versatility for all types of outdoor surfaces. Sold in packs of four wheels. To order a full set of wheels, be sure to set your quantity to two.
 
Dance wheels are usually small and hard for indoors, in rinks, or on any perfectly smooth surfaces. At 84A and 88A hardnesses, the Radar Crush will smooth out rough surfaces so that you can now boogie outside without being limited. 84A will feel a bit smoother (softer) outdoors and the 88A leans toward being a hybrid that can feel comfortable skating indoors or out. Since they are so small they will have you very close to the ground which adds a lot of stability and makes them easy to skate. These wheels would also be great replacement wheels for young roller skaters that require smaller hardware.
 
Disclaimer: Due to the size and ground clearnace of the Crush wheel, it may not be compatible with all non-PowerDyne branded plates. 
Being a small wheel, kingpin clearance issues are possible with some plates. Be sure to measure your kingpin clearance to make sure that your plates would allow for these wheels to jam.
