Directions for use - 140ML
Shake pouch vigorously before use.
Put your bike in a work stand if possible.
Remove the core of your Presta valve with the tool provided (if you have non-removable valve cores, simply pour or use the scoop to apply directly into your unseated tyre and remount).
With the valve at the 12 o’clock position, and using the non-drive side of the bike, push the pouch over the valve and rotate the valve to the 6 o’clock position.
Squeeze in the desired amount and fold the pouch to the desired fill line, re-insert the valve core and inflate the tyre in accordance with your manufacturer’s recommendations.
Repeatedly spin the wheel, shake it from side to side and hey presto, you’re now ready to rock ‘n’ roll! After use, the valve core removal tool can be added to your valve so it’s always there when you need it!
Regularly check the amount in each tyre and simply top up as needed. Keep out of reach of children. Dispose of contents/ container in accordance with local regulations.
Avoid contact with eyes. Do not drink.
