According to the website:

Its single tread that can do it all - urban/transportation, adventure riding/touring and even cyclo-cross racing - thanks to its smooth-running center section and minimal, hard-biting shoulder knobs.
Features:
Casing: 60 TPI
Bead: Wire
Compound: 70a
PSI: 75
Urban/transportation, adventure riding/touring, and even cyclo-cross racing users."
I couldn't take advantage of the New Users get $10 off or FREE shipping because you need to spend $50 and the tubes I needed are all out of stock.
I've never used these tyres but they're cheap (same price as K-mart cheapies) and anything's faster than what I'm using now. RRP is listed as $49.95 and Google cache shows cellbikes.com.au normally sell them for $19.95 or more (so 50% off is still good :)).
Oh yeah, and apparently you can pick up from their Leichardt warehouse if you order by phone
EDIT: Someone pointed out it cost more than $4.95 delivery after 2 tyres
it wants $13.95 for deliver of 4 tyres
