Art. No.: 40041. Compatible with Sparx ES100, ES200 and ES300.

Description 📝

Sparx grinding rings for the ES series are specifically designed for traditional hollow grinding (Radius of Hollow). Each ring is equipped with a microchip that communicates with your grinding machine to ensure the highest possible precision. The chip keeps track of the number of grinding passes and ensures consistent quality from the first to the last grind.

One grinding ring handles approx. 320 grinding passes. This makes it possible to sharpen about 30–50 pairs of skates, depending on how many passes are required each time (normally 2–5 passes depending on the condition of the blade).

Features ✨

• High capacity: Lasts for approx. 320 passes for long-lasting use.
• Smart technology: Built-in microchip for continuous reading and guaranteed grinding quality.
• Traditional hollow: Delivers the classic feel of sharp edges and reliable bite in the ice.
• Easy installation: Swapped in a few seconds without the need for tools.

Recommended radii 📏

Which radius you should choose depends on the skater's weight, skill level, and personal preferences:

• 13–16 mm: Best suited for figure skating and goalies (gives lots of grip/bite).
• 15–22 mm: Recommended for children and youth.
• 21–32 mm: The most common range for junior and senior players.
• 25 mm and up: Common at elite level to achieve maximum glide and speed.

Benefits ✅

• 🎯 Precise results: The same hollow depth at every grind gives a secure feel on the ice.
• 🛡️ Assured quality: The machine warns you when the ring is worn out to avoid poorer grinding results.
• 🤝 Versatility: Available in many different sizes to suit all types of skaters in the family or team.
• 🚀 Optimal glide: The ring's precision reduces friction and helps you maintain speed.

For owners of the Sparx ES series, these grinding rings are the obvious choice for a professional result at home or at the rink. By easily changing the ring, you can adjust the sharpness for different ice conditions or personal preferences. With original accessories from Sparx, you can trust that your blades are always in safe hands and ready for the next game-deciding moment.
