Rode out with mates today..and blimey had 6 yes 6 punctures on a 40 mile loop.
New tubes each time, correct tube size
Pressures - 110 - 110
5 to rear 1 to front
No thorns/ flints found each time
Most of the holes appear to be more of a slit rather than a puncture, and I'd say 4 out of the 6 are all on the inside of the tube.
Bad luck ??
I doubt it but really cannot find a cause.
