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

Product Information

A larger volume is easier to bottom-out, a smaller volume will ramp up more towards the end of the stroke. 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.

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.The minimal 1in gauge is surprisingly accurate, and the countersunk bleed button behind it is a nice addition for such a compact pump. There is a very non-linear relationship between accuracy, precision and cost,” he explains. “Accuracy and precision are different. 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. When installing the tokens, ensure you thread them securely into the top-cap and the adjacent token. Were they to come loose, they could jam inside the fork. 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.

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.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.” You do have to hold the dial at the front but rubber coating makes that comfortable, though it is possible to get your fingers trapped under the handle – hold the handle to the side, and it’s fine. While it may not be a significant factor for all bikers, consider hose length. The longer the hose, the easier it is to use.
