Lezyne Pen Gauge Hose

Lezyne’s pen gauge is a replacement specific hose for the brand’s M(edium) and L(arge) HP series mini pumps complete with integral pressure gauge, precision machined Presta/Schrader ends and durable hose.

While there’s no denying the aesthetic beauty and clever detailing, the gauge is tricky to read-especially in low light and 15 quid while not unreasonable for the quality of construction is halfway to a new pump, let alone a replacement attachment. That said, consumables are readily available from dealers meaning it should last a good while.

Measuring 19.5cm, the hose is longer than most thanks in part to the integral pressure gauge that gives readings to a 120psi (8 bar) maximum-greater than even the strongest will achieve from a frame fit, let alone pocket inflator and the red marker provides a useful in-a-glance reference, although this is something of a moot point should you be unfortunate enough to flat along a dark lane without portable illumination. In many respects it’s a double-edged sword- very user friendly and much kinder to valve ends on the one hand but less efficient than some high-pressure press-fits. Measured alongside a high quality digital model, the readings I got were very accurate and within the quoted 5psi deviation. However, regularly inspect this connection to ensure the cylinder hasn’t slackened as this not only reduces accuracy but also permits condensation inside.

Enclosure within the pump barrel provides excellent protection from damage caused by dirt, water, spills and road/trail shock. Attempts to pair it to frame fit and other mini pumps have proved a little hit and miss, limiting the appeal slightly and in this context a digital pressure gauge with backlight might be more prudent.

Verdict

Well crafted and clever hose kit but incompatibility with other brands limits appeal.
