Outdoor roller hockey wheels range from a hardness of 80a to 85a. Outdoor wheels are made hard to last longer on rough surfaces like asphalt, cement and concrete. When we play hockey outside, we look for the wheel that lasts the longest. Currently - it's the Revision Clinger (82a).
Outdoor wheels are HARD - you are going to feel the bumps in the ground and slide when stopping out in the streets. If you want a bit more cushion, grip and 'rebound' in your wheels, try using a dual pour outdoor wheel like the Konixx Pure-X Street. Another alternative for smooth outdoor concrete is a single pour indoor wheel like the Labeda Gripper (Med/Yellow, even the Softer White or Red if you are lighter) which will offer more grip.
The most common mistake is ordering the wrong size wheels. If it's your first time buying new wheels, or you just want to double check, send us a photo of your skates and we'll ensure you are getting the right sizes!
