Rockshox SID shock - potentially stupid question

Yeah, I know, no such thing as stupid questions, only stupid people. Anyway, the year-old NRS I bought in February came with no shock manual (RS SID XC). No problem, downloaded it, and I think I understand how to make adjustments.

However, the air pressures are beyond what your standard tire guage can measure. Might be able to rig up an engine compression tester and at least be able to measure the existing pressures. But then there's the problem of actually pressurizing the shock if I want to make a change. My air compressor can put out around 100 psi. The manual says the starting point is psi equal to your weight. No way I can get 165 psi from my compressor.

What gives?

you should purchase a shock pump. many have a gauge that goes up to 300psi, and they all have a leak-proof valve system so it's accurate when using such a small chamber (like an air shock).

You have to use a shock pump. Regular pumps can't reach the high pressures required by air shocks. Also - regular pumps will leak too much air when removing the valve - you will never get the air to stay in the shock.

I have the 02 SID as well. Be sure to upend your bike and let it sit for a few minutes before pressurizing the lower valve. I managed to gunk my pump the first time out.

DO NOT USE A STANDARD PUMP

Standard pumps are low pressure/high volume and shock pumps are High pressure/low volume. You can risk damaging your shock if you use a standard pump.

Get a shock pump.
