Sealr

Tubeless sealant dries out and you forget — until you're flat. Sealr tracks every bike and wheelset, then reminds you to top up before it's too late.

Tubeless is a revolution and it's never been easier, top up once every few months and your golden. The one frustration is when did I last put sealant in? forgetting to top up can leave you high and dry, or rather Flat and dry. The memory game gets harder when you have more bikes or more wheels!

Sealr fixes that. Set up each bike and wheelset once, and it reminds you to top up before the sealant runs dry.

WHY SEALR • Never get caught flat and dry, reminders land before sealant dries out, not after • One tap to log a top-up or full refresh, and your next reminder resets automatically • Track every tubeless setup you own, road, gravel, MTB, plus spare wheelsets

SET YOUR ROUTINE ONCE • Pick a top-up interval that suits your climate and how often you ride • Schedule a full refresh every few top-ups so old sealant gets cleaned out • Choose morning or evening reminders, at a time that works for you

KNOW WHAT YOU USED • Record the sealant brand and how much you added, in ml or oz • Note front, rear, or both tyres • A full sealant service history for every bike, no guessing, no cross-contamination

SIMPLE BY DESIGN • A clean garage view shows every bike's status at a glance • No accounts, no clutter — just the reminders you need • Your data stays on your device

Whether you run one gravel bike or a garage full of wheelsets, Sealr keeps your tubeless tyres ready to ride.
