The Radar Zen wheel provides you with good performance while keeping the price low. The 85a urethane makes them perfect for outdoor use along a trail, beachfront or through your local suburban streets. 

These are available in a range of colours and come in 62mm x 32mm size.

Sold in sets of 4 wheels. Most skates need 8.
This means if the wheel comes in different colours you can order 4 of each. Just make sure you get enough wheels for your skates!
