Having the correct tire pressure is an important factor for good grip and long tire life. My friend Casey brought this top quality tire gauge from the US. He almost always have nice gadget for me in his bag when we meet on business meetings. Cold you ask more from a colleague?
Intercomp is supposed to be the best gauge you can get and when I compared to my cheap old gauge to the right the Intercomp showed 1.9 bar and the cheap yellow gauge indicated 2.0. Quite a difference!
Glows in the dark too for night use.
