Sparx Radius Grinding Ring (Radius Ring)

Sparx Radius Grinding Ring – the classic hollow

The Radius Ring grinds the traditional hollow into your blade – according to Sparx, the profile that most professional and amateur players worldwide skate on. According to Sparx, every ring is laser-measured and inspected.

Select the radius you want above. You insert the ring into the skate sharpener and the rest runs automatically.

Which radius suits you?

• Small radius (e.g. 3/8" or 7/16"): deeper hollow, more grip
• Large radius (e.g. 7/8" or 1"): shallower hollow, more glide
• 1/2" is the most commonly skated radius. Sparx recommends it as a starting point, especially for younger and lighter players.
• 5/8" is, according to Sparx, a good fit for bigger and heavier players who want more glide.
• Goalies usually skate between 3/8" and 1/2" according to Sparx, depending on the bite they want.

Ring life

According to Sparx, a grinding ring lasts on average for around 60 pairs of skates – calculated with three cycles per sharpening. If you sharpen with more cycles, it will be fewer pairs. A chip in the ring stores the remaining ring life. The machine displays it and tells you when the ring needs to be replaced.
