Lezyne'sTech Drive HV's design let's you pump upTo your desired pressure with 30% fewer strokesThen comparable mini pumps.The handle barrel and shaft are made of cnc'd aluminum whileThe ends are constructed of a composite matrix material. Comes equipped withThe abs flex holes and frame mounting hardware. 90 psi max 216mm length
Strengths: Sexy packaging and presentation. Shiny beautiful finish. The overall concept and quality of the hose assembly is superb.
Weaknesses: The aluminum barrel was warped when I took it out of its logo bearing plastic bag and unscrewed its mount from the fancy plastic logo laden marketing piece of thick plastic it was attached to. First test stroke confirmed shoddy manufacturing and non uniform internal surface of supposedly high quality barrel. There was also an important rubber plug missing from one end that's supposed to be there to keep dirt out.
So just for a laugh I did a head to head comparison with a 22 yr old Blackburn Kamikaze plastic pump that refuses to die and guess which one kicks serious *ss? So I mounted the Blackburn onto its 11th bike and sent this overpriced Lezyne back for a refund. A total piece of junk in my experience.
