Reviews over the

Park Tool GG-1

Bought to lubricate my speedplays with. That would not have worked at all without this device. It can be said that it is a technically reliable device. However, I do find the ergonomics questionable. It is not so easy to grip this thing in such a way that you can press the grease nipple firmly against something and operate the plunger at the same time. When greasing speedplays, this is pretty essential anyway because you really need to push the new grease through.
