I have an old Orange P7 frame which has a disc mount. I'm looking to put an Avid BB7 on it. The info I'm getting seems to suggest that the caliper mount should be 74mm.
On my frame it measures roughly 55mm drill hole to hole. Does anyone know if the measurement changed in the past? Am I even measuring the right points?
Thanks.
