Query: Simple and works

The description of the item is a bit inaccurate. It looks like on the photo, not like described. I bought mine yesterday at local R.E.I. store, and it worked great. It was simple to use and I was done with adjusting the pressure in few minutes. On my bike, I had to remove the wheel first due to the position of the valve on the shock (Cannondale's Headshock, with valve which is likely impossible to access with any pump without taking the wheel off). If I had "classic" type of suspension fork with more accessible valve location (i.e. not needing to remove the wheel first), it would take only few seconds. Read the instructions so that you disconnect the valve correctly, to avoid loosing the pressure in the shock.
