What do you call the little rubber plug some bikes have in the stem cap bolt? Mine had one which finished it off nicely, but I've now managed to lose it.
Anyone know where to get one? I can't even find a picture to show what I'm talking about!
Headset cap will have great effect on waterproof and dustproof,which can make your headset not easy to get rust and dirty. Suitable for M6 inside hexagonal screw,easy to install. Well,bicycle handlebar stem is easy to get dirty,and therefore,we should require a cap to protect it.
