CHOOSING YOUR GRINDING RING
HOLLOW OPTIONS
TRADITIONAL RADIUS RINGS VS FIRE RINGS
SPARX RADIUS RINGS
TRADITIONAL HOLLOW
The Sparx Radius Rings produces the traditional hollows most commonly used in hockey, including the most popular 1/2” and 5/8” cuts. Choose from 18 different radius rings – from the deepest hollow for extreme grip (5/16”) to the flattest hollow for unmatched glide (1 ¼”).
SPARX FIRE RINGS
FLAT BOTTOM HOLLOW
Looking to get the grip you need with the benefit of extra glide? Our FIRE Ring hollows provide exactly what you are looking for – the best of both worlds. Available in four different cuts (3/8”, 1/2”, 5/8”, 3/4”) the FIRE ring is a re-imagined and optimized flat bottom hollow that provides improved glide while still maintain desired bite.
FLAT GRINDING RING
Have a deep nick or damage in your blade? Need to flatten your blade and set a new hollow? The all-new Sparx FLAT Grinding Ring allows you to remove the existing hollow in your skate blade so that you can easily set a new hollow. The specially formulated coarse abrasive of the FLAT Grinding Ring also allows for quick removal of skate blade damage including deep gouge and nicks.
UNDERSTANDING RADIUS OF HOLLOW
Radius of Hollow is simply how deep the groove is that is cut into the skate blade from sharpening. The deeper the cut, the more grip the blade will have on the ice. The shallower the cut, the more glide the blade will have on the ice. A smaller Radius Ring (5/16”, 3/8”, 7/16”) will cut deeper into the blade creating more bite, while a larger Radius Ring (1-1/8”, 1”, 7/8”) will not cut as deep, creating more glide.
CHOOSING THE RIGHT RADIUS OF HOLLOW
Choosing the right hollow is a matter of personal preference, whether you want more bite or more glide. The most common Radius of Hollow is a 1/2”, which is what you will find in most retail settings. We recommend 1/2” for most youth players (less body weight) and then increasing the radius (9/16”, 5/8”) as the player gets larger.
