GRINDING RINGS

sparx-dev

At the heart of the Sparx Sharpener is the Sparx Grinding Ring. Sparx Grinding Rings produce the hollow in your skate blade which creates the specific level of Grip or Glide that your blade has on the ice.  Whether you want extreme grip for those tight turns or that extra glide to beat your opponent to the puck, our 16 different Grinding Ring options have you covered.

General things to keep in mind - the rings range from 5/16" up to 1 1/4" The smaller the fraction, the more grip. Bigger fractions have more glide.

RECOMMENDATIONS 

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.
For Children/Young Players: We recommend a 1/2" Radius Ring  
Goalies: We recommend a 3/8" to 1/2" radius ring depending on how much bite you want [smaller radius/fraction = more bite] 
Adult players: Our most popular ring selection is the 1/2" Radius Ring, but advanced players may prefer 5/8" Radius Ring.

MOST POPULAR

GRIPGLIDE MATCH QUIZ

Every skater has preferences for Grip and Glide, which can sometimes make it hard to know which Grinding Ring to use. To help narrow down the options please consider taking the GRIPGLIDE Match Quiz on our mobile app. The app will ask you the skater's age, height, weight, position, skating-style, and skill level to provide recommended Grinding Ring options.

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

How long does a Grinding Ring last?

All orders, including bundles, will be shipped within approximately 1-2 business days.
