Yep
I've had four or five over the years, and they were all the same!! Funny thing about the Zefal rating on their website is that the last HPX I bought had "160psi" written on the box!! In fact, I cut it out and kept it coz i've encountered skeptics before
I started a thread about this a while ago, and some 'expert' said that max psi out of a pump is more about strength, rather that the structure of the pump....RAH ME!!!
