The forks double brace or arch, named the ‘Double Arch Design’ or DAD is a really unique feature. It adds a lot of stiffness to the fork, which makes the fork steer better, and help alleviate fork leg flex, something that 32mm stanchions are prone to do.
This Thor comes with a 7 inch PM disc brake mounts, so it is a direct mount for a 180mm/185mm rotor, 160mm will not work. Most people, myself included, are going to be running at least a 180mm rotor in front, so it is one less adapter to not have to use. I tested the fork with a 180mm and a 203mm, but for my weight of 155 lbs. the 203mm was overkill, so I stuck with the 180mm which seemed the most ideal.
I really liked this simple brake guide. No need to use any quick ties or screw in brake guide, just simply push the brake cable into the guide, and presto all done.
