Spacer measuring tool

Every thousandth of an inch counts.
The Inline Spacer Measuring Tool is engineered for skaters who chase every fraction of a second. Designed to measure the exact spacer size needed for each wheel — no matter the manufacturer — this tool helps you dial in your setup for maximum roll speed and bearing efficiency.
When your spacers match perfectly, your bearings spin freer, your wheels roll smoother, and your laps get faster. This is the kind of fine-tuning that separates good from great — and great from unbeatable.
✅ Optimizes performance across all wheel brands
✅ Ensures perfect bearing alignment and roll-out
✅ Essential for competitive inline speed skaters
Don’t leave speed to chance.
Measure. Tune. Win.
