자전거 바퀴크기와 기어비로 케이던스 와 속도 계산해보기

1인용 생활 자전거를 탔을 때에는 자전거 속도가 잘 나와서 변속과 피로도에 대하여 신경쓰지 않고 만족하며 라이딩을 하고 있습니다. 그러나, 2인용 자전거를 구매하고 라이딩하고나니 자전거 속도가 느렸을 때 오는 여러가지 단점들이 크게 다가오게 되었고, 속도 향상을 위해서 체인링, 드레일러, 변속레버, 체인, 크랭크 등 어떤것을 교체할지 고민하게되었습니다. 

 

우선, 속도 향상을 위해서, 자전거의 부품을 교체하기 전에,

자전거의 속도를 계산하는 필수적인 공식을 공부하게 되었습니다. 

 

 

자전거에는 동력계가 있으며, 동력계는 바퀴, 체인링, 스프라켓, 크랭크, 체인, 드레일러 등이 있습니다. 

이중에서 변속기가 고정되었을때, 페달을 밟았을 때 바퀴를 움직하게 하는 요소는,

페달, 크랭크, 체인, 스프라켓, 바퀴의 순서로 힘이 전달되어 자전거의 속도가 됩니다. 

특히 크랭크와 스프라켓의 톱니바퀴의 수의 비율과 바퀴의 크기는, 페달을 밟았을때 어느정도로 바퀴가 회전하는지를 결정하며, 이것은 한번의 페달링으로 영향을 받아서 직접적으로 관계있는 자전거의 속도 또는 이동거리 또는 다리에 가해지는 힘을 계산하는 요소들 입니다. 

 

1 기어비

기어비는 체인링의 톱니바퀴 갯수에서 스프라켓 톱니바퀴 갯수를 나눈 값 입니다.  

예를 들어, 체인링 톱니 갯수가 52개이고, 스프라켓 톱니 갯수가 26개이면, 기어비는 2 가 됩니다. 

체인링은 페달 크랭크암에 연결되어 있으며,

스프라켓은 뒷바퀴에 연결되어있습니다. 

페달을 1바퀴 굴렸을때 체인링이 한바퀴 돌아가고,

스프라켓이 1바퀴 돌아가면 뒷바퀴도 한바퀴 돌아가며,

체인링과 스프라켓은 체인으로 연결되어 있어서 맞물려 돌아가므로,

페달을 한바퀴 돌리면 뒷바퀴가 몇바퀴 돌아가는지를 의미합니다. 

 

 

2. 이동거리

이동거리는 페달을 한바퀴 돌리면 자전거가 몇미터를 이동하는지를 의미합니다. 

즉, 이동거리는 기어비에 바퀴 크기를 곱한 값이 됩니다. 

예를 들어, 체인링 톱니 갯수가 52개이고, 스프라켓 톱니 갯수가 26이면, 기어비는 2이고, 

바퀴 크기가 20인치이고 타이어 두께가 1.5인치이면, 둘레는 파이 x 지름 이며,

이동거리는 기어비 2 x 바퀴 둘레 1555.72 = 3111mm = 3.11미터가 됩니다. 

바퀴의 둘레 값은 아래의 표준 값을 참고하여 계산하였습니다. 

 

 

3. 케이던스 

케이던스는 분당 페달링 횟수입니다.

자전거의 속도를 표준화하기 위하여 케이던스라는 용어를 사용하였습니다.

즉, 라이더의 근력 또는 체력 또는 능력을 배제한 값입니다.  

자전거 학계에서는 케이던스 표준값을 90으로 하며, 이 값은 라이딩할때 근육 운동을 무리하지 않는 상태에서 페달링을 가볍게 하기위해 변속 기어를 설정했을 때 케이던스가 90 이라는 의미라고 합니다. 

즉, 평지에서는 케이던스를 90으로 유지하려고 할때 변속기를 7단에 가깝게 고단으로 했다면, 경사진 오르막 길에서는 변속기를 1단에 가깝게 저단으로 해야 케이던스를 90으로 유지할수 있다는 의미가 됩니다.

 

 

4. 자전거 속도

케이던스가 분당 페달링 횟수이고, 표준을 90으로 한다면,

케이던스에 이동거리를 곱하면

표준적인 분당 자전거 속도가 계산될 수 있습니다. 

 

즉,  체인링 톱니 갯수가 52개이고, 스프라켓 톱니 갯수가 26이고, 바퀴 크기가 20인치 타이어 두께가 1.5인치였을 때,

권장되는 자전거 속도는 3.11미터에 케이던스 90을 곱하면 279.9 미터/분이되며, 약 300m/m 이 됩니다. 

시속으로 변환하면 18km/h가 됩니다.  

 

 

대략 체인링과 스프라켓과 바퀴 크기와 자전거 속도의 관계를 어떻게 계산하는 방법을 알아봤습니다.

맞게 정확하게 공부하였는지는 모르겠습니다. 

그러나, 대략은 알거 같습니다.
