Abstract:
A grip for a handlebar of bicycles includes an operation layer which includes a porous PU layer and a non-woven layer which is securely attached to an underside of the porous PU layer. The operation layer is securely mounted to a sleeve and the handlebar is inserted into the sleeve. The operation layer provides shock-absorbing, non-slip and comfortable grasp to the handlebar.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    (1) Field of the Invention 
         [0002]    The present invention relates to a grip for bicycle handlebars and the grip provides shock-absorbing, non-slip and comfortable grasp. 
         [0003]    (2) Description of the Prior Art 
         [0004]    A conventional grip  2  mounted on a bicycle or motorbike handlebar is shown in  FIG. 1  and generally includes a closed end and an open end into which the handlebar  1  is inserted. The grip  2  is made by plastic material and the user&#39;s hand might slip because of sweat. In order to provide comfortable and reliable grasp to the grip  2 , bosses or raised patterns are made on the outer surface of the grip  2  so as to increase the friction between the grip  2  and the user&#39;s hand. However, the user need more comfortable and non-slip grip during severe operation of the bicycle. 
         [0005]    The present invention intends to provide a grip for the bicycle or motorbike handlebar and includes a porous PU layer and a non-woven layer and the user&#39;s hand holds on the PU layer to obtain better grasp to the handlebar. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention relates to a combination of a grip and a handlebar of bicycles, wherein the grip includes a porous PU layer and a non-woven layer which is securely attached to an underside of the porous PU layer so as to form an operation layer. The operation layer is securely mounted to a sleeve and the handlebar is inserted into the sleeve. 
         [0007]    The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
