The Specialized Windpipe that I use is underated I think. With 2 stage pumping, it can be attached to a tyre that already has 120psi in it, and can be effortlessly increased to 140psi. should one need/wish to do so. Max 220psi.
Also, the guage is very accurate, and certainly more legible than the very nice Lezyne (with guage). 300psi.
