LEZYNE PRESSURE OVERDRIVE

£150

SPECIFICATION Height: 110cm • Hose length: 120cm • Contact: upgradebikes.co.uk

The Lezyne Pressure Overdrive is designed for seating tubeless tyres. It comes with a secondary air chamber that you charge to around 120psi and then you activate the lever on the base to blow all the air into the tyre.

At £150, the Lezyne Pressure Overdrive is expensive, but the construction is superb. It has an old-school wooden handle that’s comfortable and doesn’t flex. It has an accurate digital gauge, which is top mounted, so is easy to access the different modes.

What’s less convincing is the ABS2 head. It has a reversible chuck that fits either way for the different valve types, but rather than pushing on at the Presta side it actually threads onto the valve stem. This means if the valve is slightly bent it can leak air as you’re taking it on and off. Thankfully Lezyne does include a tool on the end of this chuck, so you can at least tighten it easily.

Compared to the Lifeline Airblast tubeless pump tested here, it took more strokes to charge the Pressure Overdrive, but the latter did provide a bigger boost of air for consistent bead seating.

If you use it like a regular pump it’ll inflate road tyres easily, but with an mtb tyre 30 strokes only gets you to 24psi. It’s also not as quick to charge and when you add in the fiddly head and extra cost, it’s hard to recommend this over the Lifeline Airblast. We’re also not fans of the release lever – it really looks out of place on a Lezyne product costing £150.
