Re:
Every time I think of using mine I pick up punctures, 4 the last time all in one wheel.
Plus anything but bone dry tarmack or dry compact ground with short dry grass and they are deadly.
Bloody light though.
I think the new race semislick is the replacement for them. Added puncture protection to stop all the punctures.
But if they work for you where you ride, you'll be flying along. They where quick tyres until they punctured.
Not seen any pop up for a while.
[Roots, rocks, stones all fine with them, just the brambles and similar small thorns that often lay across a paths go right through them as there is not rubber to stop them].
