The present invention relates to a bicycle wheel, which comprises: a ring-shaped first rim portion; a hub portion placed in the center at an internal side of the first rim portion, and coupled to a rotating shaft; a plurality of connecting portions connecting an internal side surface of the first rim portion to an external side surface of the hub portion; a second rim portion coupled to an external side of the first rim portion for a brake pad to be in contact therewith; and a tire coupled to an outer circumference of the second rim portion, wherein the first rim portion includes a carbon composite material and the second rim portion includes an aluminum material. According to the present invention, the bicycle wheel is lightweight and strong, and has high elasticity and excellent heat resistance in case of braking to prevent damage. Moreover, when vibration is generated in the bicycle wheel, the vibration is absorbed in the bicycle wheel.

    본 발명은 자전거 바퀴에 관한 것으로, 본 발명은 링 형상의 제1 림부; 상기 제1 림부의 내측 가운데에 위치하며 회전축이 결합되는 허브부; 상기 제1 림부의 내측면과 허브부의 외측면을 연결하는 복수 개의 연결부들; 상기 제1 림부의 외측에 결합되어 브레이크 패드가 접촉되는 제2 림부; 상기 제2 림부의 외주에 결합되는 타이어;를 포함하며, 상기 제1 림부는 탄소복합소재를 포함하고, 상기 제2 림부는 알루미늄소재를 포함한다. 본 발명에 따르면, 가볍고 견고하면서도 고탄력이며 제동시 내열성이 우수하여 파손이 방지되며, 자전거 바퀴에 진동이 발생할 경우 자전거 바퀴에서 진동을 흡수한다.
