While it may not be a significant factor for all bikers, consider hose length. The longer the hose, the easier it is to use. Type of Gauge & the Maximum Pressure 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. 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. I genuinely enjoy reviewing and comparing products and helping people orient themselves in cycling. Road cycling is closest to me, but I also have a good grasp of other disciplines, such as mountain and gravel biking or commuting.It’s here that small gauges fall short, because they can be hard to read and the general size of the needle and print can cause an error in desired pressure. There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different. Because it’s still quite compact, we found that it does take a while to inflate a tyre but is great for suspension setup since you can use the high-volume setting to initially boost a load of air into your fork, then the high-pressure setting to fine-tune it. We managed to get about 70psi in 20 strokes.

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 sizePrecision 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.” RCT3 models offer low-speed compression adjustment, but only in the open setting 3. Low speed compression 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.” To counter such issues, Poertner suggests that whatever you choose to buy, you should treat it as a reference.
