In the Secret Squirrel club, we are currently debating whether the use of C02 cartridges has a chemical reaction with Stan's jizz thereby preventing effective sealing of holes. Thorns seem to be ok but when a bigger cut appears (within the quoted parameters) it seems not to work.
Two of us use hand pumps while another of our number uses cartridges to inflate tyres after trail side blow outs. He seems to be the only one who has real issues and more often than not, has to resort to a tube.
I always carry a 100ml bottle of jizz along with me so it is seldom a case of the goo having dried up or him having too little in his tyre.
Is this a common occurrence or is it just him? Evidence seems to suggest C02 is the culprit but might there be some other reason lurking?
