If I lose a good amount of pressure before the sealant works, is it a good idea to use CO2 to inflate the tire up to pressure? Rumor has it, the CO2 is so cold it could freeze the sealant and render it ineffective. “Wise”-tale or fiction? Time to buy a new emergency pump for the road bike and would like compact pump to fit under the saddle with the saddle bag and have seen these combo-pumps and just don’t know it the CO2 part would be counter-productive.
