Every time I go out I get at least one puncture on my (new) 2.3 high roller. They are from thorns rather than being pinch flats.
Is this to be expected or have I got a duffun?
Mine are the single-ply 60a kevlar type if that makes any difference.
The Minion i've got on the front doesn't ever get punctured, and my conti gravitys were okay too.
