Set up instructions:

1. Shake pouch vigorously before use, now turn pouch over to check particles are mixed. Put your bike in a work stand if possible. Remove the core of your Presta valve (if you have non-removable valve cores, simply pour directly into your unseated tyre and remount).
2. Ensure pouch is thoroughly shaken right before filling. 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.
3. Repeatedly spin the wheel, shake it from side to side and hey presto, you’re now ready to rock ‘n’ roll! Regularly check the amount in each tyre and simply top up as needed.
4. Before adding our sealant into your tyre, make sure any other sealant has been thoroughly removed before hand. If you get sealant on your frame, parts or clothing remove as quickly as possible with clean water and a cloth. Try not to let the sealant dry before you can wash your kit properly at home!
