Hi David, went through every tyre rack on the Newcastle bike strip today.
No luck for me :'(
But I found a 16 x 60/100(16 x 2.55, He told me? looks good) Kenda K760 Track master front knobbly 38M (medium compound).
I forgot my phone so I couldn't get a picture
But it looks a lot like this one except without the little holes in the knob centers (it had plain knobs)
I thought having the new metric coding that it would be a current Kenda line, but It seems to be discontinued on the Kenda web now?

$55. No prob to pick it up tomorrow and post it tomorrow if you want it. I am giving a driving lesson, if you want it we will be driving the bike shop
Regular registered post will cost you some where between $11 to $17 depending on your location.
Of course if you are after "original" concourse? read the other guys posts.
Pm me if you want it David, Cheers.
