Rock Shox 00.4315.023.010 High-Pressure Fork Pump, Black, 300 psi

Product Information

If you have an RCT3 model fork, the low-speed compression is adjusted using the smaller-diameter knob on the top of the right leg. 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.”

A larger volume is easier to bottom-out, a smaller volume will ramp up more towards the end of the stroke. On the downside the pump isn’t very comfortable to use since you have to grip around the gauge and the handle has quite a blunt shape. With that, see our next point. 4. Gauge accuracy doesn’t matter so much, but repeatability (precision) certainly does 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. Poertner agreed, analogising the relationship between accuracy, precision, and cost to throwing darts: accuracy being how close you are to the bullseye (for a gauge, how close is 100psi to 100psi?) while precision is how repeatable your darts are.To test these pumps properly, we recruited Kappius Components to custom-build an inline digital gauge. This one reads 0-200psi with a +/- 1% accuracy. David Rome/Immediate Media Bleed valve

Bleeding pressure was also the best, with a knob that can be opened exactly how you wish. The whole pump is fairly compact, although it’s not light to ride with. This pump also has the ability to switch between high-volume and high-pressure modes, and the head is compatible with both Presta and Schrader valves. 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.PSI is a unit of pressureexpressed in pounds of force per square inch of area. It stands for Pounds per Square Inch. 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.
