Dura Ace triple- different chain-rings
The Japanese one size fits all model is too restrictive for me.
I wish to replace the small and middle chain-ring with , say, a 34 and a 44 tooth ring. Or a 36 and and 46.
The gap from middle to big chain-ring is is too big for me, and this change would give me small jumps at the 20 to 22 mph range for me.
Shimano only has one size for the small and middle chain-ring on the Dura Ace triple. Does anyone know of someone who makes chain-rings that would fit?
