Yes, this was my first port of call! But when I look up for example what you suggested they all seem to say 160 front or, for example. 180 rear. I haven’t come across ones that say 160 front or 160 rear. Is it that you use the same mount front and rear but it gives you 160 spacing or 180 spacing rear?
That's right. The mounts used are the same, but the one on the rear needs 20mm more height.
So a 160mm rotor on the back would need the same adapter as a 180mm rotor on the front.
