車架的後輪鈎原本是不適用內變倒煞的，除了現在必需配合Chain Tensioner 使用，
本來內變倒煞的零件 Washer
不能使用在車架上，倒煞時所產生的扭力會令後輪軸移位。
所以還得自己制作小零件使用。
你可以看到我在後輪軸與後貨架孔之間有一片鐵片。
用了兩點鎖緊，這便防止了後輪軸移位的現像。
我己經嘗試過在高速大落斜時，使用倒煞至响胎。
後輪軸分毫沒有移動過。

I have to tell "coaster brake + chain tensioner with spring" not just trouble. It is dangerous! Chain loose is possible and will lose the brake. May be some chain tensioner without spring is more suitable. I'm use the 52T chainrings + 16T cog + 98 links chain without any chain tensioner and pull the rear wheel to the most end with the parts my own made. It should have tension enough on my frame to keep the chain doesn't walk off. Does it work??? I'll tell if I'm alive.
