I try to fit an I.S mount for a 140mm Disc rotor on seat stay , but no standard library for 140mm (only for 160 and 180mm).
I can see that the dimentions (G and E) are not changeing when toggling between 160 and 180mm rotor disc.
Will this also be the case with a 140mm rotor? The I.S mount is the same , but you change the IS to post adaptor?
My problem is that I have made a frame with the I.S mount for 160mm rotor , useing a 140mm disk and Shimano IS to Post adaptor for 140mm rotor , the brake pads "just" bide on the rotor. If it was "biding" 2mm lower if would be perfect . The only way to do this , as I see it , is either move the I.S mount , or modify the IS to post adapter.
