I have a k7 that i have swapped some 78f comstars onto, along with the swingarm and forks from the 78f.
anyways I have spent some time searching for a good replacement tire as I noticed a GIANT nail through my tire.
I had just gotten the wheels balanced and fitted with new tubes after i got them powdercoated which makes me a bit upset the new rear tube has <50miles on it.
The tire is overdue for a change and just looking to see what size and make/model of tire people like to put on.
I included the pic of the nail for fun.
and bike for even more fun
