| firstly, why do you think a heavier chain combined to the same size diameter sprockets be any different to the smaller gauge chain with matching sprockets. all outside diameters are the same from thin to larger chain / sprockets set ups, the only difference is the spacings of the teeth and chain links. example; a thin chain set with 6-68 is the same as a thick chain with 6 -68. this is why you can,t use either a thin chain on a thick chain sprocket and vise versa. its like trying a motor cyle chain on a push bike. won,t work. |
