Setting the fluid level in front forks accurately is critical to the safe handling of your bike and this tool makes it a piece of cake.

The vast majority of workshop manuals will give you an air height for the fluid level ie the measurement from the top of the fork tube to the fluid level often with spring out and the fork at maximum compression. You simply tighten up the setting screw on the aluminium ring at the correct air height, fill the fork tube to approximately the correct height, by eye and then a little bit more. Push the metal tube into the fork leg and suck the excess fluid out using the syringe; when the fluid is at the correct height the syringe will start to suck air instead of suspension fluid. You then move to the next leg safe in the knowledge that both legs will contain exactly the same height of fluid.

This tool is of better quality than the above but not up to the professional workshop version below. As with all tools from Laser Tools it is well made.
