There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different. If you’ve ever used a low-quality pump, you know how unpleasant the experience can be. You may feel like the pump could break at any moment. To learn more about the issues with gauge accuracy and precision, we consulted Josh Poertner, the CEO of pump manufacturer Silca.

For more aggressive riders, I recommend one or two tokens at 160mm”, explains Cancellier. “For each 10mm decrease in travel, I add one token. For example, 150mm would be two or three tokens, 140mm three or four tokens etc.”

To counter such issues, Poertner suggests that whatever you choose to buy, you should treat it as a reference. However, it requires fewer strokes to inflate the pressure you need, making it ideal for mechanics in a workshop. Finance is subject to application, financial circumstances and borrowing history.

Thus, heavier riders running higher air pressures will likely require more rebound damping than lighter riders.The pump itself is solid, with a bleed valve, extra-long hose and comfy handle, though it has quite a small volume so 100 strokes equates to about 81psi. 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.” If you want both pumps in one, this is simply your one and only good choice. It’s also the only pump on test to include an under bottle-cage mount – in case you’re keen to get it covered in mud.

But Poertner pointed out that there are numerous moving parts that must also be very carefully constructed to produce precision – and that fixing these issues requires design and manufacturing processes with nonlinear cost/benefit relationships. With such high pressures, you’ll want a comfortable handle. Some pumps feature a fold-out handle, others offer little to grasp onto. Hose Some pumps claim to have special valve heads that isolate attachment and the valve pin engagement; others don’t say much about the fact. I analogise it to throwing darts: accuracy is how close you are to the bullseye, so for a gauge, how close is 100psi to 100psi?

Also, some riders prefer a slightly faster fork while others a slower one. Whichever you prefer, you should aim to have the fork returning in a controlled manner that isn’t so fast as to return violently, or excessively slow.” 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.”
