Reasons to buy: Presta adapter means this pump works on tyres and suspension, high pressure and high volume modes, neat design, frame clip included, compact size A bleed valve is important for fine-tuning your suspension if there’s too much air. Most pumps here feature a basic button that lets you release bursts of air, while the Syncros takes a different approach. With such a high maximum pressure, we found it surprisingly good at lower pressures too; although double the numbers in the same gauge space does inevitably mean a loss of accuracy. So be warned that the gauge is tough to read at lower pressures. While researching, I could not find many technical specifications for this pump. However, technical details are often unnecessary when the pump functions well, which is the case with this one. If you’re always hitting the 20 but you can tightly cluster your darts you’re inaccurate, but precise. Similarly, if you hit left of bullseye, bullseye and right of bullseye, your average accuracy would be good, but your precision would be bad,” he said. “For pressure gauges, accuracy is a combination of design and manufacturing of the internals, followed by a careful calibration to make sure that 100 = 100.”

Each pump was assessed on its general usability, comfort and build quality. Additionally, we recruited Brady Kappius to custom-build a high-accuracy inline gauge to ensure repeatable results in our testing. With this, our benchmark digital gauge offers 1 per cent verified accuracy. A larger volume is easier to bottom-out, a smaller volume will ramp up more towards the end of the stroke.

There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different. The build quality is similar to that of generic pumps supplied with suspension products. It’s perhaps not at a level you’d expect for the price, but the metal pump body is likely to outlast the gauge’s service life as oil, vibration and general age can all degrade accuracy. Ok I figured out the issue for real this time. I wasn't screwing in the hose hard enough. I had twisted the hose on all the way on with medium pressure but apparently, at least in my particular scenario, I needed to twist the hose on more forcefully. To learn more about the issues with gauge accuracy and precision, we consulted Josh Poertner, the CEO of pump manufacturer Silca.

Precision is how repeatable your darts are. If you aren’t always hitting the 20 but you can tightly cluster your darts, you are inaccurate but precise. Similarly, if you hit left of bullseye, bullseye and right of bullseye, your average accuracy would be good, but your precision would be bad.”
