I'm planning to replace the 160mm front disc on my 2009 BMC Team Elite 02 MTB by a 180mm rotor, but I'm quite puzzled by the number of possible adapters.
The calipers are part of a combined brake/shifter Shimano M 765 and a rough measurement of the space between the bolts is 70mm
The fork is a Manitou Black Comp 125mm
Unfortunately, I can't add a picture on this forum yet.
Could anyone let me know the model of adapter I need, for example on AE pages such as 4000389793602 or 1005003707892599 or 1005004369743094 ?

Thanks
