Hi all,
I just picked up a pair of Saint 810 disk brakes for my DH bike. I haven't gotten adapters yet, as I was wondering whether I can use any 74mm to Boxxer 203mm adapter, or if I need to specifically buy the shimano part.

For reference, the shimano piece of metal comes in at $38, everybody elses' comes in at around $10. Unless there's something I'm missing, they should do the same thing and hold the caliper in the same place.
