GRINDING RINGS

sparx-dev

While there are many options available, the most common grinding rings are the 1/2" and the 5/8" Radius Ring™. Through our testing, we have determined that a 1/2" Radius Ring is a great starting point for smaller, younger players. Many adult players skate on a 1/2" radius as well. We have, however, found that larger, heavier players actually do quite well on the 5/8" radius. A flatter radius, the 5/8" allows heavier players to sufficiently grab an edge for turning and stopping but provides great glide as more of the blade remains above the ice surface.

How do I know which Grinding Ring to choose?

The easiest answer is that the Radius Ring™ produces a traditional "radius of hollow" (ROH) sharpening. Unless you know you skate on a flat-bottom profile, you will likely want to choose the Radius Ring at checkout. The Radius Rings work for both player skates and goalie skates. The FIRE Ring™ produces a flat-bottom cut with radius edges. The flat bottom hollow is designed to allow more glide in the blade without sacrificing the edges that you want/need for quick stops and sharp turns.

What's the difference between Radius & FIRE Rings?

If you’re freshening up your blades after every skate, you’ll get 50-60 sharpenings (or even more!) per ring (Radius Ring or FIRE Ring) and if you’re sharpening your skates after every 5-6 hours of ice time, you’ll get about 40 sharpenings
