Thanks Ron H, looking at pictures online left the mistaken impression that the 140 and 150 versions are different visa a visa the centre rib, I appreciate your effort in getting to bottom of this issue.
I from Ontario Canada and some buddies and I are planning a Continental Divide Ride next June, and we're looking to swap out to some aggressive tires, perhaps in Alberquerque. I am currently running E07s but they will pretty much done by the time we get down there. I am trying to decide if a fresh set of E07s will do the Divide nicely or if I would be better off with E10s.
