yes, came stock in tubless on the cannondale. imho, good rear, not a good front. if your a pythons, geax mezcal kind of person youl love them. if your a larsen, square block tread kind of person, youl find them twitchy.

they are quite fast rolling though. problem is when you ocme to a corner. they are goodish through sand as well if i recall correctly.

i swapped my front out for a larsen and was much happier.
