Sparx Grinding Ring Comparison

Understanding Radius of Hollow

A smaller Radius Ring (5/16", 3/8". 7/16") will cut deeper into the blade creating more bite. A larger Radius Ring (1-1/8", 1", 7/8") will not cut as deep, creating more glide.

Choosing the Right Radius of Hollow

The most common Radius of Hollow is 1/2". Sparx recommends 1/2" for most youth players and increasing the radius (9/16", 5/8") as the player gets larger.

Sparx Fire vs Sparx Radius

The Radius Ring produces a traditional "radius of hollow", which is recommended for most skates. The Fire Ring produces a flat-bottom cut with radius edges.
