FWIW, my 85 ST400 had a 116mm spindle with the original iwo ring crankset. A triple I purchsed for possible hill/mountain use(SOTR?) is speced for118mm spindle. Do you have the spec for your crankset? 127mm seems quite wide! For me a 118 mm spindle tried on my double provided noticeable knee displacement to the right and eventually knee discomfort. Thead carefully!
