A slider is a consumable
A spark slider consists of ferrocerium rods in a printed base. On contact with the asphalt the ferrocerium grinds away and that is what makes the sparks. That material does not come back. The slider wears away as a whole, just like your pucks. There are no refills and no inserts: when it is gone, it is gone, and you replace it.
Roughly 2 to 3 minutes of contact time
Count on roughly 2 to 3 minutes of total contact time per slider, in short runs of 4 seconds max. Indicative, based on our first test series; we keep measuring and will update the number.
How fast that happens depends on your pressure, your riding style, the asphalt and above all on how strictly you keep to the 4-second rule. Longer runs wear the slider down faster and can let the pocket go soft.
How we measured
The number comes from a fixed test method:
- Materials: bases in PLA, PETG and ASA, each with ferrocerium from the same batch.
- Setup: a grinding disc at fixed rpm with calibrated contact pressure, as a stand-in for asphalt.
- Cycle: 4 seconds of contact, 5 seconds of cooldown, until the material is gone.
- Temperature: IR thermometer on the base after every cycle, so we know which material can take the heat.
- Repeats: 3 repeats per material. We publish the average and the spread.
Indicative. The 2 to 3 minutes come from our first test series and are not a guarantee. We keep measuring and will update the number on this page and on every product page.
