I'm looking to adapt my 160mm post mount front fork to accept a 180mm rotor.
As I'm looking between adapters, I find them falling into two very distinct categories, and I'm wondering if there are any trade offs or reasons for preferring one style over the other.
The first style bolts to the 160mm post mounts with separate standard length bolts, then juts out farther and drops down to accept the brake with standard length bolts.
The second looks smaller and lighter, and comes with longer bolts and rounded washers that go through both the brakes and the adapter and into the 160mm post mount.
Here is the difference when mounted:
Would there be any particular advantages of one way or another?
