Apologies all for the bump on this, but I've started to get worried that the rigid version of this tyre has bitten the dust.
In times past I got them from Evans, AW in Reading, Pedal On in Tadley, et al.
The only ones I can find now are folding versions, and they don't fit the rims on my singlespeed bike at all.
I also struggle with Gators, and Vittoria Rubino Pro folding are a non-starter.
Have considererd Schwalbe Duranos, but must admit being able to fit Hardcases with no more than a Crank Bros speed lever is very satisfying and I'd rather not give it up!
