Description

Grip extension

This creation mainly discloses a grip extension device, especially a grip extension device for a bicycle grip.

In an environment where bicycle sports are so popular, the athletes are more particular about the bicycle body. The size of each part of the vehicle must be set according to the external conditions of the rider's body. Even the vehicle must be provided with an adjustment function for the rider to respond differently. Adjust by riding environment.

As far as the handlebars of bicycles are concerned, the long handlebars have a large range of hands when they are held, which can achieve high operational stability and accuracy, and a short length of the handlebars. Small, with the body movement can reduce the wind resistance, but also can reduce the width of the body, each has its own advantages and disadvantages.

However, since the handlebars are made of integrally formed tubular members, the conventional bicycle needs to change the length of the handlebars by directly replacing another handle of a different length, which is very troublesome in operation.
