Birzman Maha Grand Push & Twist III
Birzman’s Maha Grand Push & Twist III is a fair all-rounder track pump with a good build quality and feel in use, but air loss can be an issue.
The main body is constructed with CNC’d aluminium, and there are two feet that are reasonably long, adding stability, while the handle is a classy-looking wooden unit.
The barrel is tilted by 5 degrees towards your body for a more ergonomic feel, which is most noticeable when pushing higher pressures. It’s fairly tall, too, which is handy for taller riders.
It doesn’t have a huge volume, making each stroke of the pump fairly easy to push, even at higher pressures, but mountain bikers will find it takes more strokes than many other track pumps to get a tyre up to pressure.

I found that I could seat mountain bike tyres fairly easy with the Maha Grand, but due to that lower pressure I had to pump fairly swiftly to get fast enough air flow into my tyres.
The hose is long, which is always handy. For example, it’s possible to comfortably attach the head to tyre valves when the bike is in a workstand.
The Push & Twist head can be difficult to screw onto Schraeder valves, though, which led to a fair bit of air loss. Also, if you have short valves, or a lot of your valve is hidden within a deep-section rim, you might struggle to get the head to grip easily. That said, once on, the bleed valve at the head means easy pressure regulation.
The gauge is located by the feet of the pump and it’s fairly large. However, with closely spaced psi and bar indicators, it’s a cluttered looking gauge – especially because it shows up to 220psi.
I also didn’t find it the most accurate at mountain bike pressures, making it better suited to road cyclists.
