One of my new 20's has a leaky spoke
Got the tyre off it today and it has been damaged by whoever put the tyres on. If you pump it up (40psi) its flat within the hour.
anyway heres a pic of the damage, its the rubber inner spoke seal luckily not the hard outer spoke seal.

So what do you reckon i should fix it with?
I was thinking of some kind of silicon with a car punture type patch over the top
