Tubeless sealant, measured
SealSense tells you how much sealant is left in your tubeless tire — in millilitres. About a minute at the bike. No tools, no valve core out, no guessing on the trail.
01The problem
Tubeless sealant quietly dries out over a few months. Most riders find out how much is left the hard way — on the trail, with a hole that won’t seal.
Shaking the wheel for a slosh tells you something is in there. It doesn’t tell you whether it’s enough.
02A minute at the bike
Hook the unit onto the tire from inside a lifted wheel, then roll the wheel down one zone at a time, striking where the dial points you. Read the result. That’s the whole session.
Roll the wheel until the needle sits in zone D · 30–35°.

04The unit
Small, tool-free and patent-pending. It lives on the wheel only while you measure — then it’s back in the bag.
01Clips on
Hooks over the tire from inside the wheel. No tools, nothing to undo.
02Guides you
The app walks you through each measurement, step by step.
Drag to turn
03Bluetooth
Connects straight to the app in your browser. Nothing to install.
04USB charging
Charges over USB. Hold the button until the LED blinks and it’s ready.
Good to go. Check again in a few weeks.
05The reading
Every reading comes with a plain instruction — ride, top up soon, or top up now. And if a measurement isn’t solid, SealSense tells you instead of guessing.
06My SealSense
Describe each tire once. Pick it and measure whenever you like. Every reading is kept, and each tire’s page shows how its sealant is drying — and when it’s due.
Nothing to sign up for
Open the app, switch the unit on, connect from the toolbar. That’s it.
Your data stays yours
Tires and readings live on your device. Export them to CSV whenever you like.
Runs in the browser

Readings are estimates — a guide for when to top up, not a substitute for a proper tire inspection. When a measurement isn’t solid, the app tells you instead of guessing.
