I'm in a bit of a pickle. I ordered ST150 spec brake discs and calipers, but the disc doesn't fit within the caliper bracket. Are the standard st150 discs also 25mm thick? I can't find any carriers at all, and the calipers look exactly the same as the puma ones, so I don't see how they should fit over these bigger discs. Is there a flaw in my thinking here?
