CYCLING WEEKLY9 OUT OF 10
There's plenty to praise the new Blackburn Piston 4 for - starting with a large, easy to read gauge at the top of the barrel that's clearly marked in both psi and bar.
The Piston 4 stands at just under 68cm tall, so its steel barrel is long and there's plenty of length to the pump stroke, making for easy inflation to high pressure.
The barrel is securely bolted to a large steel baseplate so the pump is stable even on rough ground. You get a wide cylindrical plastic handlem which also makes for comfortable, easy pumping. Blackburn quotes a maximum pressure of 220psi/15 bar.
Blackburn's pump head has a robust metal locking lever, works with both presta and schrader valves and includes a release button.
The Blackburn Piston 4 feels like a pump that will last forever - indeed, Blackburn offer a lifetime warranty.
